INTRODUCTION TO COMPUTER
INTRODUCTION TO COMPUTER
Computer:
computer is an electronic device which process input data according to the instructions given by the programmer and produces the desired information as output and store the information.
Data:
Data represents the raw factors of observation.
Eg: Numbers, alphabets & images
Information:
Information is processing of data i.e. the data that deal to transform that is useful & meaningful from is known as information.
Input:
Sending the data & command through the computer is known as input.
Output:
The result displayed by the computer is known as output.
Processing:
A work done by computer to give the result is known as processing.
Storage:
The place where result is stored or saved is known as storage.
Basic components of computer:
Basically computer has two components:-
1) Hardware component
2) Software component
Hardware component:
Hardware refers to physical components of computer.
Eg: keyboard, monitor, hardisk, microprocessor etc.
Software component:
Software reffers to set of instructions return to a computer to perform particular task.
Eg: C, C++, JAVA, ASSEMBLES.
Software is again divided in to two types:
1) System Software
2) Application Software
Sytem software:
System software reffers to collection of programs which provides suitable servers to users and makes computer uses friendly.
Eg: Compilers, Interpritor, Assemblers, Operating system etc.
Copilers:
Compilers translates high level language to machine level language. It translates all programs at a time.
Eg: Pascal, Cobalt, ‘C’ Compilers.
Interpritor:
It translates high level language to machine level language but it translates statement by statement one after the other.
If there is any error in any statement it shows the error message after reverification of error only it will continue to meet statement.
Operating software:
Operating software is a set of pragrams which acts as interface between user and computer.
Eg: WindowsXP, WindowsSP, linox etc.
Application software:
It reffers to program written by programmers to perform their tasks.
Application software is divided in to several types:
programming language:
A communication between users & system is known as computer language.
Eg: C, C++, JAVA, COBALT, PASCAL.
Packages:
Packages cannot be modified by the users.
Eg: MSOFFICE, ORACLE, DBMS.
Presentation software:
It is used for presenting colourful presentations.
Eg: Paintbrush, Powerpoint.
Assemblers:
Assemblers are used to convert the assemble level language to machine level language.
