Charles Babbage is known as “The Father of Computer”. The first use of the word "computer" was recorded in 1613 referring to a person who carried out calculations, or computations, and the word continued with the same meaning until the middle of the 20th century. ENIAC was the 1st computer of world.

HISTORY OF COMPUTER

DATA AND INFORMATION

Data is a collection of raw facts, figures and symbols such as numbers, words, images, video which is given to the computer as the input. Computers manipulate data to create information.

Information is data that is organized, meaningful, and useful. The information can also be put in computer storage for future use.

Software Software is a set of programs,

procedures, algorithms and its documentation concerned with the operation of a data processing system.

TYPES OF SOFTWARE

System software System software is designed to operate computer hardware to provide basic functionality and to provide a platform for running application software.

Application software Application Software is developed to perform in any task that benefits from computation. It is a set of programs that allows the computer to perform a specific data processing job for the user.

HARDWAREThe term hardware covers all

of those parts of a computerthat are tangible objects. 

TYPES OF HARDWAREINPUT DEVICES

The devices which takes input are called Input Device.

Example : Keyboard, Mouse, Joystick etc.

OUTPUT DEVICESThe devices which gives output

are called Output Devices.Example : Printer, Speaker,

Headphone etc.

TYPES OF HARDWARE

Processing DevicesThe devices used for processing are called

Processing Devices.Example : C.P.U

Storage DevicesThe devices used to store information are called Storage Devices.Example : Pan drive, Floppy etc.

CENTRAL PROCESSING UNITThe central processing unit (CPU) contains electronic circuits that cause processing to occur. The CPU interprets instructions to the computer, performs the logical and arithmetic processing operations, and causes the input and output operations to occur. It is considered the “brain” of the computer.
