Computer: A Computer is a General purpose machine, commonly consisting of digital circuitry, that accepts (inputs), stores, manipulates, and generates (outputs) data as numbers, text, graphics, voice, video files, or electrical signals, in accordance with instructions called a program.

• Father of the computer – Charles Babbage.
• Father of the modern computer – Alan Turing.
• Basic Architecture of Computer: John Von Neumann (1947-49).
• First Programmer: Lady Ada Lovelace (1880).
• First Electronic Computer: ENIAC (1946) – J.P. Eckert & J.W. Mauchly.
• The first computer for the home user introduced – IBM in 1981.

Computer – An Introduction
• A computer is a device that can receive process and store data.
• However, all computers have several parts in common:
• Input devices allow data and commands to the computer (Mouse, Keyboard etc.)
• Memory for storing commands and data.
• Central Processing Unit which controls the processing.
• Monitor Process the information in the form of output.

Types of computers

Computers range in size and capability. There are supercomputers, very large computers with thousands of microprocessors that perform extremely complex calculations.
There are tiny computers embedded in cars, TVs, stereo systems, calculators, and appliances. These computers are built to perform a few number of tasks.
Desktop computers
1. Desktop computers design is made for use at a desk or table.
2. They are typically larger and more powerful than other types of personal computers.

Peripheral Devices

1. The peripheral device connects to a computer system to add functionality. Examples are a mouse, keyboard, monitor, printer and scanner.
2. A computer peripheral is a device that connects to a computer but is not part of the core computer architecture.
3. The core elements of a computer are the central processing unit, power supply, motherboard and the computer case that contains those three components.

Types of Peripheral Devices

• There are many peripheral devices, but they fall into three general categories:
• Input devices, such as a mouse and a keyboard
• Output devices, such as a monitor and a printer
• Storage devices, such as a hard drive or flash drive

Computer Knowledge – Main Parts of Computer

Hardware
• Computer hardware is what you can physically touch includes the computer case, monitor, keyboard, and mouse.
• It also includes all the parts inside the computer case, such as the hard disk drive, mo
• there-board, video card, and many others.
Input Devices
• In computing, an input device is a peripheral (piece of computer hardware equipment) used to 
• e data and control signals to an information processing system.
• It will control devices such as a computer or information appliance.
Examples: keyboards, mice, scanners, digital cameras and joysticks.
