the role of libraian and information center in nigeria

INTRODUCTION Library is defined as an organized collection of published books and audio-visual materials with the aid of the services of staff that are able to provide and interpret such materials as required, to meet the informative research, educational and recreational needs of its users. It is an agency through which sources of information of accumulated knowledge and experience are selected, acquired, organized, preserved and disseminated. Libraries and information centres provide a much wider range of information services from local, state and federal governments; organizations/institutions within and outside the country among others for the people. With the provision of variety of information sources, users of libraries and information centres are exposed to different information with their respective values. A very important word, which is functionally synonymous with library, is “information dissemination”. The word ‘library’ can be used inter-changeably with ‘information centre’. Though an information centre is not necessarily a library, a library is by its function is an information centre. Library services are not completely divorced from information services, which are also provided by other agencies such as the mass media, and at times more effectively and competitively. This was the view of Broadbent (1982) when he stressed that the above point illustrates one significant point, namely, that as much as the library has informational role in the society, being one component of communication system, it has other vital social functions to perform. These he explained might be recreational, cultural, social or educational. Information centres are the veritable repository of knowledge that underpins socio-economic, political and cultural development of any country. They are avenues of knowledge that constitute one of the principal instruments in building a richer and better social order. In his own view, Beckman (1982) explained that information centres are viewed as being more dynamic, whereas library has historically been known as depositories for books and journals. Information centres, he said are involved in the analysis, synthesis, transmission and repackaging of data and information. But as new technologies allow libraries to become more involved indifferent types of activities performed by the so called information centres, distinction between libraries on one hand and information centres on the other hand is no longer valid he concluded. Therefore, for the purpose of this paper, the two terms “Library” and “information centre” will be used interchangeably. THE ROLE OF LIBRARIES IN POLICY IMPLEMENTATION If communication and information remains an effective ingredient in the implementation process, then, the question of how the policies will be disseminated to the intending public becomes crucial. One of the primary functions of the library is the dissemination of information. Thus, the library is assumed to play a crucial role in policy implementation. This is done by ensuring that the policies are disseminated to the public (library users). Library has a role to model the value of the information mosaic built-up over time and across cultures. Other than the library, there is no agency of government that has a wide knowledge of the social significance of the accumulated resources of knowledge in the public domain (Alan, E. S., 2002).In line with the challenges of implementing government policies in Nigeria, it has saddled Nigerian libraries and information centres with the responsibility of safe-guarding the information of today for a better tomorrow. In a bid to ensuring the effective implementation of government policies, libraries and information centres are expected to play a pivotal role in the following areas: -Creating awareness: awareness on the said policy must be created by the library to avail the public (library users) the necessary information on the policy. This can be done by making available books and information related to government policies in the library. -Ensuring feedback: the library can also help in gathering feedback on government policies from the library users. If the government can get adequate feedback on her policies, it will help her in the formulation of new policies as well as improving on the existing ones. -Aiding the development of good policies: the library provide necessary information on government policies which in turn aids the development of such policies. COMPLEMENTARY ROLE OF LIBRARIES AND INFORMATION CENTRES The functions and objectives of libraries and information centres vary according to the mandate of the parent body where the centre is situated. A library is expected to acquire resources that are meant to reflect the peculiar program of the institute which serves as its parent body. Libraries and information centres serve as store-houses of all government policies for future reference. For any current policies, it is always easy to sponsor jingles and advertisement of such in media houses, but the fact remains that “policies come and go” but their success or failure becomes a history that must be documented for reference purpose. How then will the coming generations be able to refer to such policies if not properly documented, organized and preserved for future purpose. For example, Operation Feed the nation (OFN) by Obasanjo’s regime in the year 1976, through perfect documentation will avail the present generations the opportunity of knowing it as if they were part of the implementation process. Even though some other agents can also supply required information on policies to the people, the library has the advantage of being consistent and people can visit it any time desired. Whereas, governments and policies come and go according to their own program of activities, which may not coincide with the period the people actually require the information. Libraries and Information centres play the complementary roles of transmission and dissemination of the policies to the people. No matter how well a policy may be, if not known to the people, they may not understand it. The present federal government policy on amnesty is a good example. A democratic society that believes that political power belongs to the people must open knowledge to its entire people, since equal access to knowledge is a pre-requisite to equal political power. The country is divided into Federal, State and Local Governments just to bring the government closer to the people. Therefore, the government should bring information about their policies closer to the people via these organs. This can start from the apex library in the country – National Library of Nigeria; down to the state libraries and further to the grass-root – the local government or council libraries. It is not enough to initiate policies aimed at enhancing the quality of life of the people, effort must also be made to encourage people to be actively involved in making the policy a success. This according to Aguolu (1984) can be actualized by dissemination of information on that policy,which has been shown to be a major factor because of its potentials for giving new knowledge, raising consciousness, strengthening links and understanding among the populace. This opinion also tallies with Aboyade (1984) as she affirmed that library is in a better position to ensure, among other things, that the provision of information will not just be a patchy affair dictated more by the need for propaganda, but will be an on-going business constantl opening up all the policies of the government so as to make life better for the masses. It is the responsibility of libraries and information centres to gather all the policies and create links between the various organs and agents of government. Aguolu (1984) concluded that libraries and information centres take cognizance of the entire spectrum of the government bringing their policies together by:- -Sustaining increasingly complex operations of the government, facilitating their decision-making process with economy of the country. -Providing a relationship between the people and the various component of government. -Providing a useful internal political mechanism for gaining budgetary support. -Providing means of communicating the goal and program of the government to the people. CONCLUSION If government policies will be well implemented, then the public must be well informed and familiar with these policies. Libraries and information centres as agencies for social, political, cultural, economical and educational change therefore have a big role to play in the implementation of any government policy. They are expected to acquire different sources of information to process, preserve and disseminate them to satisfy the information needs of their users. This goes beyond providing only printed sources of information but also non print information to the entire public. Libraries and information centres are expected to be platforms of communication between the government and the public, therefore various government policies implementation committees are expected to work in collaboration with libraries and information centres in discharging their duties. Libraries and information centres on their own part should brass-up to cope with the present challenges of today’s library users, especially on ICT world. Information, which is almost synonymous to the word library, has also helped in making the library relevant in the society. For example, information and communication research and data, as well as monitoring and evaluation are supportive strategies for achieving the National Gender Policy in Nigeria (Federal Ministry of Women Affairs and Social Development 2006). Therefore, the library will continue to be a relevant institution in policy implementation as long as information and communication remains vital. Hence, If the government will avail the library, the necessary support as well as adequate supply of information, implementation of policies will become effective and easier. RECOMMENDATIONS Libraries and information centres have played an important role in the implementation of government policies, by collecting, organizing, managing and disseminating information resources for both current use and for posterity. But the challenges faced by the libraries and information centres from internal and external factors have also posed a lot of set-back on the effectiveness of the role of libraries and information centres in policy implementation. The following points are hereby recommended: -Government should use the library as a major source of feedback on her policies -Government should establish special libraries in national, state and local levels on policy. Such libraries can be named ‘A library of government policy’ where any information related to any government policy will be available for the betterment of both the government and the governed. -All stakeholders in the implementation of government policies need to improve their effort in collaborating with libraries and information centres to achieve the aim of implementing those policies. -Libraries must be adequately financed by the government -Government should always include the library in her policy implementation committees. -Library should be given more concentration and importance especially by government at all level. -Library and information centres should engage themselves in informing and educating other outlets. -Library and information centres should stand out from the crowd of other information handlers particularly government agents like extension workers, private or road side information mishandles.

term paper on 1960 independence constitution

ABSTRACT The Independence Constitution of 1960 and the Republican Constitution of 1963 have provisions for the protection of fundamental human rights. The 1979 and the 1999 constitutions went further by providing a bill of right. This entrenchment of human right provisions in our constitutions was aimed at creating a society which protects political freedom as well as the social and economic well-being of Nigerians. However, despite the guarantee of fundamental rights and liberties in the Nigerian constitutions since 1960, the country has had the misfortune of military interruption in its polity. This had profound and far reaching effects on the promotion and protection of democratic values such as freedom of expression among Nigerians. This study examines the legal framework within which freedom of expression is practiced in Nigeria due to that fact that concepts such as freedom of expression are subject to various philosophical interpretations. It gives insight into the genesis of right of expression in the modern jurisprudence and provides a proper conceptual framework of human right from which freedom of expression is derivable. The study also examines the judicial attitudes in Nigeria in interpreting the subject matter. Furthermore, some limitations to right to expression which are premised in substantive and procedural laws are also considered. The practical relevance of social justice in the enforcement of this right in Nigerian also forms part of the study. INTRODUCTION Nigeria's first constitutions were enacted by order in council during the colonial era, when the country was administered as a Crown Colony. The constitutions enacted during this period were those of 1913 (which came into effect on 1 January 1914), 1922, 1946, 1951 and 1954. In 1946 a new constitution was approved by Westminster and promulgated in Nigeria. Although it reserved effective power in the hands of the Governor-General and his appointed Executive Council, the so-called Richards Constitution (after Governor-General Sir Arthur Richards, who was responsible for its formulation) provided for an expanded Legislative Council empowered to deliberate on matters affecting the whole country. Separate legislative bodies, the houses of assembly, were established in each of the three regions to consider local questions and to advise the lieutenant governors. The introduction of the federal principle, with deliberative authority devolved on the regions, signaled recognition of the country's diversity. Although realistic in its assessment of the situation in Nigeria, the Richards Constitution undoubtedly intensified regionalism as an alternative to political unification. The pace of constitutional change accelerated after the promulgation of the Richards Constitution. It was suspended in 1950 against a call for greater autonomy, which resulted in an inter-parliamentary conference at Ibadan in 1950. The conference drafted the terms of a new constitution. The so-called Macpherson Constitution, after the incumbent Governor-General, John Stuart Macpherson, went into effect the following year. The most important innovations in the new charter reinforced the dual course of constitutional evolution, allowing for both regional autonomy and federal union. By extending the elective principle and by providing for a central government with a Council of Ministers, the Macpherson Constitution gave renewed impetus to party activity and to political participation at the national level. But by providing for comparable regional governments exercising broad legislative powers, which could not be overridden by the newly established 185-seat federal House of Representatives, the Macpherson Constitution also gave a significant boost to regionalism. Subsequent revisions contained in the Lyttleton Constitution, named for Oliver Lyttelton,1st Viscount Chandos and enacted in 1954, firmly established the federal principle and paved the way for independence. PARLIAMENTARY SYSTEM “Parliamentary system of government means a prime minister is the head of government, and the president is the head of state. The PM is chosen by a party, not directly by the people. In Britain, for example, the Queen/King is the Head of State, while the PM is being chosen by the party that wins the majority of the votes, or through coalition. “Until the January 1966 coup of Nigeria, Nigeria was practicing parliamentary system of government. Nnamdi Azikiwe was the President then, while Tafawa Balewa was the first and the only Prime Minister that Nigeria has ever had. It was a coup d’etat by renegade Nigerian Military officers that jettisoned the system and subsequently lead to the changing of system of government in Nigeria from parliamentary to presidential. “Unlike presidential, parliamentary system of government is less costly, as the PM and other ministers are ‘part-time workers’. While in presidential system, there are senior and junior full-time ministers. Also, the government is answerable to the Congress, unlike in Nigeria, where resolution of the National Assembly is useless. The parliamentary system is more suitable for multi-cultured countries like Nigeria, where regions can back a party based on their tribal and regional inclination. “The procedure for removing a president is much easier in a parliamentary system. Once the PM loses a vote of confidence or his coalition partners pull off, then the government falls. But in the presidential system, there have to be a two-third majority in votes even before the trial commences. The president is called for a hearing, a committee is set by the chief justice, the report will come back to the National Assembly before the impeachment continues. This is too enormous in case of urgency. “Nigeria is a country where tribal, regional, and party sentiments surpass nationalism and patriotism. A tribal chauvinist is more honored than a nationalist. How can people of South-East continue to love Ojukwu – who intended to divide Nigeria – more than Gen T. Y Danjuma, Gowon and Buhari who fought for Nigeria’s unity? If Nigeria’s inclination is through tribal sentiments, then the parliamentary system is better for us. “If the parliamentary system is not be allowed to come back, why not consider adopting the Swiss style of government? In Switzerland, the parliament chooses people from major tribes (in the case of Nigeria), or regions. Each person will govern the country for a year, and then step down and become a minister. Thus, all hosen candidates do their single-year term before being replaced with other people. “Nigeria needs a better system of government. This federal style is not working at all, favouring the looters, undermining the will of the people. “I call on the National Assembly to bring back our parliamentary system through a referendum, or adopt the Swiss style of government in Nigeria. If either of the two is accepted and implemented well, that will help solve regional, tribal and sectarian struggles, also conflict for gaining upper hand in power in Nigeria.” The Federation of Nigeria was granted full independence on 1 October 1960 under a constitution that provided for a parliamentary government and a substantial measure of self-government for the country's three regions. From 1959 to 1960, Jaja Wachuku was the First Nigerian Speaker of the Nigerian Parliament - also called the "House of Representatives." Jaja Wachuku replaced Sir Frederick Metcalfe of Britain. Notably, as First Speaker of the House, Jaja Wachuku received Nigeria's Instrument of Independence - also known as Freedom Charter - on 1 October 1960, from Princess Alexandra of Kent, The Queen's representative at the Nigerian independence ceremonies. The Federal government was given exclusive powers in defense, foreign relations, and commercial and fiscal policy. The monarch of Nigeria was still head of state but legislative power was vested in a bicameral parliament, executive power in a prime minister and cabinet, and judicial authority in a Federal Supreme Court. Political parties, however, tended to reflect the make up of the three main ethnic groups. The Nigerian People's Congress (NPC) represented conservative, Muslim, largely Hausa and Fulani interests that dominated the Northern Region. The northern region of the country, consisting of three-quarters of the land area and more than half the population of Nigeria.[23] Thus the North dominated the federation government from the beginning of independence. In the 1959 elections held in preparation for independence, the NPC captured 134 seats in the 312-seat parliament. Capturing 89 seats in the federal parliament was the second largest party in the newly independent country the National Convention of Nigerian Citizens (NCNC). The NCNC represented the interests of the Igbo- and Christian-dominated people of the Eastern Region of Nigeria.[23] and the Action Group (AG) was a left-leaning party that represented the interests of the Yoruba people in the West. In the 1959 elections the AG obtained 73 seats. The first post-independence national government was formed by a conservative alliance of the NCNC and the NPC. Upon independence, it was widely expected that Ahmadu Bello the Sardauna of Sokoto, the undisputed strong man in Nigeria who controlled the North, would become Prime Minister of the new Federation Government. However, Bello chose to remain as premier of the North and as party boss of the NPC, selected Sir Abubakar Tafawa Balewa, a Hausa, to become Nigeria's first Prime Minister. However, in 1962, a faction arose within the AG under the leadership of Ladoke Akintola who had been selected as premier of the West. The Akintola faction argued that the Yoruba peoples were losing their pre-eminent position in business in Nigeria to people of the Igbo tribe because the Igbo-dominated NCNC was part of the governing coalition and the AG was not. The federal government Prime Minister, Balewa agreed with the Akintola faction and sought to have the AG join the government. The party leadership under Awolowo disagreed and replaced Akintola as premier of the West with one of their own supporters. However, when Western Region parliament met to approve this change, Akintola supporters in the parliament started a riot in the chambers of the parliament.[25] Fighting between the members broke out. Chairs were thrown and one member grabbed the parliamentary Mace and wielded it like a weapon to attack the Speaker and other members. Eventually, the police with tear gas were required to quell the riot. In subsequent attempts to reconvene the Western parliament, similar disturbances broke out. Unrest continued in the West and contributed to the Western Region's reputation for, violence, anarchy and rigged elections. Federal Government Prime Minister Balewa declared martial law in the Western Region and arrested Awolowo and other members of his faction charged them with treason. Akintola was appointed to head a coalition government in the Western Region. Thus, the AG was reduced to an opposition role in their own stronghold. INDEPENDENCE CONSTITUTION (1960) Nigeria's first constitution as a sovereign state was enacted by a United Kingdom|British order in council so as to come into force immediately upon independence, on 1 October 1960.

CONCLUSION The point has been made that right from the colonial period, Nigeria has had a plethora of constitutions. Starting from the 1914 initiative of Lord Lugard to the Independence constitution, the people of Nigeria were hardly involved in the drafting of their constitutions. We opined that the colonial state used constitution drafting to consolidate imperial strategies. The post-colonial period does not look promising. Post-colonial Nigeria until recently was dominated by the military who in a bid to earn legitimacy had drafted one form of constitution or the other. The current 1999 constitution is characterized by a number of deficiencies that have inevitably led to a clamour for its disuse. For one, it has all the trappings of a unitary constitution. The concept of federalism as embedded in the constitution is only a paid lip service. Nevertheless, the document may not be perfect, but it signals a starting point. In due course, it would be amended to reflect the views of Nigerians. In this process, it would fulfill one of the attributes of a constitution, which is that it should reflect the ethos of the people. REFERENCES  Adeyemi, O.

output and input devices with their functions

TEN INPUT DEVICES AND THEIR FUNCTIONS Mouse Mouse is most popular pointing device. It is a very famous cursor-control device having a small palm size box with a round ball at its base which senses the movement of mouse and sends corresponding signals to CPU when the mouse buttons are pressed. Generally it has two buttons called left and right button and a wheel is present between the buttons. Mouse can be used to control the position of cursor on screen, but it cannot be used to enter text into the computer. Keyboard Keyboard is the most common and very popular input device which helps in inputting data to the computer. The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing additional functions. A keyboard consists of a series of keys that can be pressed to input commands or letters. These are used to write documents but can be used to navigate user interfaces in lieu of a mouse. Joystick Joystick is also a pointing device which is used to move cursor position on a monitor screen. It is a stick having a spherical ball at its both lower and upper ends. The lower spherical ball moves in a socket. The joystick can be moved in all four directions. The function of joystick is similar to that of a mouse. It is mainly used in Computer Aided Designing (CAD) and playing computer games. Light Pen Light pen is a pointing device which is similar to a pen. It is used to select a displayed menu item or draw pictures on the monitor screen. It consists of a photocell and an optical system placed in a small tube. When the tip of a light pen is moved over the monitor screen and pen button is pressed, its photocell sensing element detects the screen location and sends the corresponding signal to the CPU. Scanner Scanner is an input device which works more like a photocopy machine. It is used when some information is available on a paper and it is to be transferred to the hard disc of the computer for further manipulation. Scanner captures images from the source which are then converted into the digital form that can be stored on the disc. These images can be edited before they are printed. Digitizer Digitizer is an input device which converts analog information into digital form. Digitizer can convert a signal from the television or camera into a series of numbers that could be stored in a computer. They can be used by the computer to create a picture of whatever the camera had been pointed at. Digitizer is also known as Tablet or Graphics Tablet because it converts graphics and pictorial data into binary inputs. A graphic tablet as digitizer is used for doing fine works of drawing and image manipulation application Magnetic Ink Card Reader(MICR) MICR input device is generally used in banks because of a large number of cheques to be processed every day. The bank's code number and cheque number are printed on the cheques with a special type of ink that contains particles of magnetic material that are machine readable. This reading process is called Magnetic Ink Character Recognition (MICR). The main advantages of MICR is that it is fast and less error prone. Optical Character Reader(OCR) OCR is an input device used to read a printed text. OCR scans text optically character by character, converts them into a machine readable code and stores the text on the system memory. Microphone Microphone is an input device to input sound that is then stored in digital form. The microphone is used for various applications like adding sound to a multimedia presentation or for mixing music. Track Ball Track ball is an input device that is mostly used in notebook or laptop computer, instead of a mouse. This is a ball which is half inserted and by moving fingers on ball, pointer can be moved. Since the whole device is not moved, a track ball requires less space than a mouse. A track ball comes in various shapes like a ball, a button and a square TEN OUTPUT DEVICES AND THEIR FUNCTIONS Monitors Monitors, commonly called as Visual Display Unit (VDU), are the main output device of a computer. It forms images from tiny dots, called pixels that are arranged in a rectangular form. The sharpness of the image depends upon the number of pixels. LCD / flat-panel display The flat-panel display refers to a class of video devices that have reduced volume, weight and power requirement in comparison to the CRT. Printer A printer is an external hardware device responsible for taking computer data and generating a hard copy of that data. Printers are one of the most used peripherals on computers and are commonly used to print text, images, and photos. PLOTTER A plotter is a computer hardware device much like a printer that is used for printing vector graphics. Instead of the traditional toner, plotters use a pen, pencil, marker, or other writing tool to draw a design onto paper. Though once widely used for computer-aided design, these devices have more or less been phased about by wide-format printers. Plotters are used to produce a hard copy of schematics and other similar applications. Projector Often no larger than a toaster and only weighing a few pounds, a projector is an output device that can take images generated by a computer and reproduce them on a large, flat (usually lightly colored) surface. For example, projectors are used in meetings to help ensure that all participants can view the information being presented. The picture is that of a View Sonic projector. Speaker A speaker is a term used to describe the user who is giving vocal commands to a software program. The Frequency response is the rate of measurement of the highs and lows of the sounds the speaker produces, Total Harmonic Distortion (THD) is the amount of distortion created by amplifying the signal, and the Watts is the amount of amplification available for the speakers. GPS Short for Global Positioning System, GPS is a network of satellites that helps users determine a location on Earth. Today, with the right equipment or software, anyone can establish a connection to these satellites to establish his or her location within 50 to 100 feet. Sound Card Alternatively referred to as a sound board or audio card, a sound card is an expansion card or integrated circuit that provides a computer with the ability to produce sound that can be perceived by the user through a peripheral device like speakers or headphones. Although the computer does not need a sound device to function, they are included on every machine in one form or another; either in an expansion slot (sound card) or on the motherboard (onboard). Video card Alternatively referred to as a display adapter, graphics card, video adapter, video board, or a video controller, a video card is an internal circuit board that allows a display device such as a monitor to display images from the computer. Jump drive Alternatively referred to as a USB flash drive, data stick, pen drive, memory unit, keychain drive and thumb drive, a jump drive is a portable drive that is often the size of your thumb that connects to the computer USB port. Today, flash drives are available in sizes such as 256MB, 512MB, 1GB, 5GB, and 16GB and are an easy way to transfer and store information. 7 INTERNAL COMPONENTS OF THE SYSTEM UNIT Motherboard The motherboard is the body or mainframe of the computer, through which all other components interface. It is the central circuit board making up a complex electronic system. A motherboard provides the electrical connections by which the other components of the system communicate. The mother board includes many components such as: central processing unit (CPU), random access memory (RAM), firmware, and internal and external buses. Central Processing Unit The Central Processing Unit (CPU; sometimes just called processor) is a machine that can execute computer programs. It is sometimes referred to as the brain of the computer. CPU Diagram There are four steps that nearly all CPUs use in their operation: fetch, decode, execute, and writeback. The first step, fetch, involves retrieving an instruction from program memory. In the decode step, the instruction is broken up into parts that have significance to other portions of the CPU. During the execute step various portions of the CPU, such as the arithmetic logic unit (ALU) and the floating point unit (FPU) are connected so they can perform the desired operation. The final step, writeback, simply writes back the results of the execute step to some form of memory. Random Access Memory Random access memory (RAM) is fast-access memory that is cleared when the computer is power-down. RAM attaches directly to the motherboard, and is used to store programs that are currently running. RAM is a set of integrated circuits that allow the stored data to be accessed in any order (why it is called random). There are many different types of RAM. Distinctions between these different types include: writable vs. read-only, static vs. dynamic, volatile vs. non-volatile, etc. RAM CD CDs are the most common type of removable media. They are inexpensive but also have short life-span. There are a few different kinds of CDs. CD-ROM which stands for Compact Disc read-only memory are popularly used to distribute computer software although any type of data can be stored on them. CD-R is another variation which can only be written to once but can be read many times. CD-RW (rewritable) can be written to more than once as well as read more than once. Some other types of CDs which are not as popular include Super Audio CD (SACD), Video Compact Discs (VCD), Super Video Compact Discs (SVCD), PhotoCD, PictureCD, CD-i, and Enhanced CD. CD-ROM Drive There are two types of devices in a computer that use CDs: CD-ROM drive and a CD writer. The CD-ROM drive used for reading a CD. The CD writer drive can read and write a CD. CD writers are much more popular are new computers than a CD-ROM drive. Both kinds of CD drives are called optical disc drives because the use a laser light or electromagnetic waves to read or write data to or from a CD. DVD DVDs (digital versatile discs) are another popular optical disc storage media format. The main uses for DVDs are video and data storage. Most DVDs are of the same dimensions as compact discs. Just like CDs there are many different variations. DVD-ROM has data which can only be read and not written. DVD-R and DVD+R can be written once and then function as a DVD-ROM. DVD-RAM, DVD-RW, or DVD+RW hold data that can be erased and re-written multiple times. DVD-Video and DVD-Audio discs respectively refer to properly formatted and structured video and audio content. The devices that use DVDs are very similar to the devices that use CDs. There is a DVD-ROM drive as well as a DVD writer that work the same way as a CD-ROM drive and CD writer. There is also a DVD-RAM drive that reads and writes to the DVD-RAM variation of DVD. Floppy Disk A floppy disk is a type of data storage that is composed of a disk of thin, flexible(“floppy”) magnetic storage medium encased in a square or rectangular plastic shell. Floppy disks are read and written by a floppy disk drive. Floppy disks are a dying and being replaced by the optical and flash drives. Many new computers do not come with floppy drives anymore but there are a lot of older ones with floppy drives lying around. While floppy disks are very cheap the amount of storage on them compared to the amount of storage for the price of flash drives makes floppy disks unreasonable to use. Hard Disk Drive A hard disk drive (HDD) is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Just about every new computer comes with a hard disk these days unless it comes with a new solid-state drive. Typical desktop hard disk drives store between 120 and 400GB, rotate at 7,200 rpm, and have a madia transfer rate of 1 Gbit/s or higher. Hard disk drives are accessed over one of a number of bus types, including parallel ATA(also called IDE), Serial ATA (SATA), SCSI, Serial Attached SCSI, and Fibre Channel. DISCUSS ON THE FIRST, SECOND AND THIRD GENERATION OF COMPUTER First Generation (1940-1956) Vacuum Tubes The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts. The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951. Second Generation (1956-1963) Transistors Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors. Though the transistor still generated a great deal of heat that subjected the computer to damage, it was a vast improvement over the vacuum tube. Second-generation computers still relied on punched cards for input and printouts for output. Second-generation computers moved from cryptic binary machine language to symbolic, or assembly, languages, which allowed programmers to specify instructions in words. High-level programming languages were also being developed at this time, such as early versions of COBOL and FORTRAN. These were also the first computers that stored their instructions in their memory, which moved from a magnetic drum to magnetic core technology. The first computers of this generation were developed for the atomic energy industry. Third Generation (1964-1971) Integrated Circuits The development of the integrated circuit was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers. Instead of punched cards and printouts, users interacted with third generation computers through keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. Computers for the first time became accessible to a mass audience because they were smaller and cheaper than their predecessors.
