TYPES OF COMPUTER

    Super Computer

Supercomputers are the fastest computer and have a large data storage capacity. A supercomputer can execute more than 100 million instruction per second.

It has multiple processors which are based on parallel processing architecture for achieving high speed. It is made for some special purpose. It can support more than 1000 users at a time. It is used for Space Research, satellite management, Wheatear forecasting Aerodynamics, and complex computation.

Ø First Indian Super Computer “PARAM2000”.

Ø The first supercomputer is CDC 6600 (designed by CDC Control Data Corporation in USA).

Ø The first five fastest supercomputer of the world are

1.      Summit (US)

2.    Sierra (US) ...

3.    Sunway TaihuLight (China) ...

4.    Tianhe-2 (China) ...

5.     Frontera (US)

Ø Speed of Supercomputer is measured in FLOPS.

Ø FLOPS (Floating Point Operation per Second).

MAINFRAME COMPUTER

A mainframe is a very large in size computer which is capable of supporting hundreds or even thousands of user simultaneously. It is designed for specific purpose.

Mainframe systems are used in Banks, hospitals, railways, educational institutions etc.

Examples: - IBM 4381, CDC cyber series, etc.

MINI COMPUTER

A minicomputer supports the working of several user at a time. It has a larger memory, high storage capacity & larger computing power than a microcomputer.

It has multiprocessing system and is capable of supporting upto 200 users simultaneously.

Example: HCL Magnum, VAX7500 etc.

It is used in big Organization for Computer Aided Design, industrial application, etc.

MICROCOMPUTER

A microcomputer is meant for a personal computer. It is a small size computer that has microprocessor chip as CPU. It is also called Desktop computer, PC, computer etc.

It was first developed by IBM (International Business Machines)

These are common, economical and easy to use. Examples IBMPC100,200  Apple Macintosh.

Personal Computers which are used at home, School and offices including desktops, laptops and tablet PC.

It is used for study, Entertainment, office works.

MOBILE

A mobile is a hand held, portable & wireless telecom device. The prime functionality of a mobile phone is to make Voice call, SMS and MMS.

With the advancement of computing technology, such phones are called smartphone.

Console Game

Console Game is a device that is primarily designed to play games with the help of keyboard & joystick that is displayed on a TV or Monitor.

Ex- Xbox, PlayStation series.

Embedded Computer

An embedded computer is a combination of computer & other device that is designed or made to serve a predefined or specific works.

Ex- ATM, Washing machine, Microwave Oven etc.        

BASED ON WORKING:-

ANALOG COMPUTER

Analogue computers are designed to process analogue data. Analogue data is continuous data that changes continuously and cannot have discrete values. We can say that analogue computers are used where we don't need exact values always such as speed, temperature, pressure and current.

DIGITAL COMPUTER

Digital computer is designed to perform calculations and logical operations at high speed. It accepts the raw data as input in the form of digits or binary numbers (0 and 1) and processes it with programs stored in its memory to produce the output. All modern computers like laptops, desktops including smartphones that we use at home or office are digital computers.

 HYBRID COMPUTER

Hybrid computer has features of both analogue and digital computer. It is fast like an analogue computer and has memory and accuracy like digital computers. It can process both continuous and discrete data. It accepts analogue signals and convert them into digital form before processing. So, it is widely used in specialized applications where both analogue and digital data is processed. For example, a processor is used in petrol pumps that converts the measurements of fuel flow into quantity and price.

BASIC STRUCTURE OF A COMPUTER SYSTEM

Computer Function A computer performs action and accomplishes its task in three basic stages namely:- INPUT – Input is the data that is fed into the computer by the user. PROCESS – Processing refers to the series of action by which the computer converts raw data into information. OUTPUT – Output is the result which is termed as information. Input Unit Data and instructions enter a computer through an input unit in a form that depends upon the input device used. Ex- Keyboard, Mouse, Joystick, Scanner etc. CENTRAL PROCESSING UNIT (C.P.U) CPU is also known as the brain of the “Brain of Computer”. As it appears as a hardware component, but it is also a functional component of a computer system. Functional Elements of a CPU        1.        Arithmetic Logic Unit(ALU)        2.        Control Unit(C.U)        3.    ...

DEVICES USED IN NETWORK

  1. MODEM: It stands for Modulator- Demodulator. A   modem is a peripheral device which modulates ( convert   digital signals to analog signals) and demodulates( convert   analog signals into digital signals) at the local workstation.   The sending and receiving ends of the communication must   have a modem. Now a days mobile phones have inbuilt   modem devices that help to browse internet.      2. Switch: A network switch is a small hardware device that is used to amplify data signals & create smaller network segment or several subnets of bigger network. It is used to prevent overloading of data in the traffic of a network. It is also responsible for forwarding and transforming data packets between the sub networks.    3. HUB:   A hub is a hardware device which provides common connection point to connect several devices together in a network. It contains multiple ports on which wo...

Application OF Computer

Communication : - In the past, people used to communication through letters, telephones etc. The advent of computers has made it possible to share or exchange information in real time (instant). Information can be textual, graphics or visual from any corner of the world in different ways. Like – Email, Online chatting, Video conferencing, FTP (File Transfer Protocol), Telnet, Social Networking. News & Broadcasting : The delivery and reception of news has changed dramatically with the advent of computers. Earlier, Journalists used snail mail, reel-to-reel recorders, dark-room processing for photos and typewriters for composing contents. But now computers have facilitated in Instant Broadcast, Online Newspapers, Online News Channels, etc. Social Networking: Before the advent of computer, people used to interact with friends and relatives in closed groups and meet them during family functions, religious ceremonies and gatherings at local temples, gurudwaras, mosques or church...
