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.

Computer Generations

 Computer Generations   Computers have evolved over time through different generations, each marked by significant technological advancements and changes in design and architecture. These generations are often categorized based on the underlying hardware and the key developments that distinguish one Generation from another. Let's explore the main computer generations: First Generation Computers    The First Generation of computers refers to the initial period of electronic computing, characterized by the use of vacuum tubes as the primary electronic component. This Generation spans the 1940s and 1950s and is marked by groundbreaking developments in computer technology.  Examples of First-Generation Computers:  o ENIAC (Electronic Numerical Integrator and Computer): Completed in 1945, ENIAC was one of the first electronic general-purpose computers. It was designed to calculate artillery firing tables for the United States Army during World War ...

Computer Basic

  The word “computer” comes from the word “compute”, which means to calculate”. Charles Babbage is known as the ' Father of computer' .  A computer often referred to as a “data processor” because it can store, process, and retrieve data whenever desired.  The activity of processing data using a computer is called data processing.    Data processing consists of three sub activities:- (1)          Capturing input data (2)          Manipulating the data and (3)          Managing output results. Data : - Data is raw material used as input to data processing. Data can be anything like numerical, non-numerical or a mixture of both. Information : - Information is processed data obtained as output of data processing. Computer: - A computer is an electronic device which performs numerical calculation and logical calculation at hig...

Office Package and Features of Office Package

Most of the official jobs today are dependent on computers. Computer helps in accomplishing different types of official tasks with the help of 'Office Package'. With the help of 'Office Package ' to accomplish basic tasks like typing and composing letters, doing calculations and comparisons, manipulation data and generating multiple types of reports, making presentation for demonstration, seminars etc.   For example: MS Office, OpenOffice, etc. Office package includes the following applications: 1. Word Processor:  A word processor is a type of application software that enables to create a documents by enabling to type text, insert page number, header, footer, edit, modify , and to take print or save documents in soft copy for future use.   2. Spreadsheet:   A spreadsheet package is an application software that stores data in an organized way and help to  analyse, calculate, compare the data or values. It also enables to present information in graphs, pie c...
