Introduction of Computer

Introduction of Computer

A computer is an Electronic device that reads data and processes to perform tasks. It’s made up of physical parts e.g. a CPU, monitor, keyboard, memory, storage, etc. There is much software also installed in it to provide instructions to the computer hardware.
Computers are basic devices for modern life and are also necessary for a wide range of industries.

Types of computer

There are two bases on which we can define the types of computers. We will discuss the type of computers on the basis of size and data handling capabilities 

Computers are mainly categorized into three types

  1. Analog Computers
  2. Digital Computers
  3. Hybrid Computers

1. Analog Computer

Analog computers calculate continuous data using physical qualities such as voltage and current, making them perfect for analytical-based exercises, engineering, and control systems.
Here are some of the examples –

 

2. Digital Computer

 

A digital computer processes separate information by calculating with binary digits (0s and 1s) and is commonly utilized in modern computing for a wide range of activities requiring accuracy and flexibility.

  1. The Microcomputer
  2. Mini Computer
  3. mainframe computer
  4. The Supercomputer

2.1 The Micro Computer

A microcomputer is a complete computer of a small size, designed to be used by one person at a time. A microcomputer is generally known as a personal computer (PC), It is based on a single-chip microprocessor. 
Examples of Microcomputer –

2.2 Mini Computer

A Mini computer is a multi-user computer smaller in size than a mainframe, designed to be used by many people at the same time. Usually, it’s used in small offices and computer labs where all the terminals are connected to a single CPU.
Examples of Minicomputers are – CII Mitra 15, IBM midrange computers, Hewlett-Packard HP 3000 series and HP 2100 series etc.
 
 
 
 

2.3 Mainframe Computer

Mainframe computers are high-performance computers that can process billions of transactions at a time, A lot of devices can connect with these types of computers for tasks that require reliability, speed, and security. Mainly used for bulk data processing, Large-scale transaction processing, and managing large organizations.
Examples of Mainframe computers are – IBM z16, IBM System z9, HITAC S-3800

2.4 Super Computer

The Supercomputer is exceptional in terms of performance. Supercomputers operate at extremely high speeds relative to all other computers. They are the most advanced & fastest computers for handling large databases and performing resource-intensive calculations, that general-purpose computers can’t handle. usually, they are used for Nuclear fusion, Weather forecasting, Space programs, etc.
Note – India’s first supercomputer is PARAM 8000.
Examples of Supercomputers – Frontier, PARAM 8000, CDC 6600, IBM 7030, etc.
 
 
 
 

3. Hybrid Computer

A hybrid computer combines analog and digital computer abilities collecting continuous data through analog components and performing complicated calculations through digital components, making it suitable for specific scientific and commercial uses.
Here are some of the examples of Hybrid Computers –
