(b) What are the classifications of computer? Explain the features of 4th generation and 5th generation of computer. 6+5=11
Ans: Computer Generations and their features
The computers have been grouped into chronological categories, called generations. Computer generation means a step of advancement in technology. It also reflects the growth of computer industry. The advancement in technology existed not only in hardware but also in software. The evolution of modern computer is divided in different generations as below:
1. First Generation: The first generation of computers was developed in late 1940s. In this generation of computers, vacuum tubes were used and these were bulky in size. These computers were very expensive to operate and in addition to using a great deal of electricity, the first computers 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. It would take operators days or even weeks to set-up a new problem. Input was based on punched cards and paper tape, and output was displayed on printouts.
2. Second Generation: In the generation of computers, solid state devices called transistors, diodes etc. were developed by William Shockley and colleagues at Bell laboratories. These solid state devices were used in place of vacuum tubes. This replacement increased the speed of computers and other drawbacks were reduced. Second generation computers were smaller in size, cheaper in manufacturing. These computers occupied lesser space and consumed lesser power.
3. Third Generation: These computers have secondary storage devices and new input and output devices like visual display terminals, magnetic ink readers and high speed printers, integrated solid state circuit (IC chips). I.C. chips increased the speed of these computers. These computers performed the arithmetic and logic operations in micro- seconds (Millionths of a second) or even in nano-second (Billionths of a second). The size and cost of these computers have decreased considerably.
4. Fourth Generation: Integrated Circuits Technology was further developed. In 1971, INTEL Corp. of USA developed the IC chips which have the entire computer circuit on a single silicon chip. These chips are called microprocessors. These microprocessors gave birth to micro-computers called micro-processors. In 1976, Steve Wozniak developed a series of micro-computers called .The Allple Series.. These computers were the most modern computers. These were much cheaper relative to performance in comparison to early computers.
5. Fifth Generation: Fifth generation computers are those computers, which not only have the advanced capabilities like speed, accuracy, storage and retrieval capabilities of other computers but have also additional ability to think and make decisions. The ability of intelligence in computers is called Artificial Intelligence (AI). Japanese have named this generation of computers as KIPS (Knowledge Information on Processing System).
5. (a) What is computer network? Explain the types of network. Explain the applications of Internet in business. 2+4+5=11
Ans: Computer Network: A collection of computers and terminal devices connected together by a communication system is called a computer network. This collection of computers may include large-scale computers, medium-scale computers mini-computers and microcomputers. The set of terminal devices may include intelligent terminals, dumb terminals, work stations and communication hardware. The interweaving of computing and communication had led to information networks of great complexity and utility. Transmission lines can be used to connect a computer to another computer or a computer terminal to a computer.
Different types of Networks
1)      Wide Area Network (WAN): Wide area network is a inter connected data communication network that covers a wide or large geographical area with various communication facilities. Such communication facilities can be long distance telephone service, satellite transmission and under-sea cables. It interconnects different sites, computer installation and user terminals spread over great distance (nationwide or even worldwide). The WAN typically involves best computers and many different types of communication hardware and software, e.g. of WAN are interstate banking network, airline reservation system etc.
2)      Local Area Network (LAN): Ans. Local area network or LAN is a network of interconnected data communication devices. LAN covers a limited geographical area; it can be within a department or division that belongs to the organization. LAN enables sharing of resources like hard disks, printers and also data created. LAN uses high-speed media and are mostly privately owned and operated.
3)      Metropolitan Area Network (MAN): MAN is a network spread over a city. It is somewhere between a LAN & a WAN. It sometimes refers to network of LAN within a metropolitan area. MANs are based on fiber optic transmission technology and provide high speed interconnection between site. Example: cable TV networks that are spread over a city can be termed as MANs.
4)      Virtual Private Network (VPN): A VPN is a private network that uses a public network (i.e. the internet) to connect remote sites or users together without paying the long-distance telecommunication charges that are levied for conventional network links. VPN provides a gateway between a corporate LAN and the internet and also allow access to a corporate network’s mail, shared files or intranet and also handles the security and privacy issues.
