COMPUTER BASIC KNOWLEDGE



What is Computer : Computer is an electronic device that is designed to work 

with Information. The term computer is derived from the Latin term ‘computare’, this means

 to calculate or programmable machine. Computer can not do anything without a

 Program. It represents the decimal numbers through a string of binary digits. The Word

 ‘Computer’ usually refers to the Center Processor Unit plus Internal memory.


Charles Babbage is called the “Grand Father” of the computer. The First mechanical computer designed by Charles Babbage was called Analytical Engine. It uses read-only memory in the form of punch cards.


Computer is an advanced electronic device that takes raw data as input from the user and processes these data under the control of set of instructions (called program) and gives the result (output) and saves output for the future use. It can process both numerical and non-numerical (arithmetic and logical) calculations.



Digital Computer Definition

The basic components of a modern digital computer are: Input Device, Output Device, Central Processor Unit (CPU), mass storage device and memory. A Typical modern computer uses LSI Chips.  Four Functions about computer are:



 Accepts data  Input
 Processes data  Processing
 Produces output
  Output
 Stores results  Storage

Computer once meant a person who did computations, but now the term almost universally refers to automated electronic machinery. The first section of this article focuses on modern digital electronic computers and their design, constituent parts, and applications. The second section covers the history of computing.

 Computer all parts details Here are the  components  and peripherals necessary to assemble a basic modern  PC  system: Motherboard. Processor. Memory (RAM) Case/chassis. Power supply. Floppy drive. Hard disk. CD-ROM, CD-RW, or DVD-ROM drive. Computer - Definition, parts, functions and its advantages                                            An electronic data processing device, which requires input raw data for processing and generates the output in desired form. It stores the data in its memory which can be accessed any number of times for reference from its memory. It is made up of a lot of electronics, software and mechanical parts. A computer is divided into three basic units namely: Input Unit Central Processing Unit Output Unit These units are defined as below: 1) Input Unit As the name suggests, this unit contains devices with the help of which the data is entered into the computer. This unit is a basic requirement for computer system. The input devices are of many types such

                                Computer Hardware Physical structure that houses a computer's processor, memory, storage, communication ports and peripheral devices. Each of these components (called devices) have a different purpose, which may be either accepting inputs, storing data or sending outputs. For example, a mouse and a microphone are input devices used to record user activities and transform them into data that is transmitted to the system unit. A hard disk is a storage unit where data is stored and accessed by other devices. A monitor or a speaker are output devices that transform processed data into (respectively) video and audio signals. Usually, the core components that represent the bare minimum that allow a computer to function are: Processor (CPU) The component that processes and executes inputs received from hardware and software. Motherboard A mainboard that provides basic connection between all the other hardware components and devices (internal and external).
