What is Computer?
We can describe computer definition in this way .
A type
of machine that manage ,controls and
show different kinds of programs to for useful tasks to the users. Computer gives
proper response to the users through the set of instructions likes
(applications) arranged in proper order
on device . It has capacity of storage along with execution benefits. Computers can
work on both complex and simple
operations. Based on types of actions,
·
Wires transistors
·
Circuits
·
hardware parts
Computer designs with both software and hardware.
Software is a process which preparing and
perform program through instructions and
data.
General computers performed following types of components in hardware.
1.
CPU
2.
Memory
3.
I/P Devices

O/P Devices
CPU:
CPU means (Central
Processing Unit ) it maintains
three kinds of activities with several kinds of operations like store the data and processing the data. PU is a major part of central processing unit computer
that tells about to the computer to
perform work in every time.
Memory:
Memory is most essential part of computer that
use to store data, run programs and etc. It categorized into some
types those can work at special purpose.
I/P devices:
In this
devices computer takes data that which is
useful to the computer that processed data and provide output from other devices.
O/P devices:
Input devices take data from users and process
then give input to the computers. After
process the data of input is made proper
output will release to the users from output devices.
Computer Types:
1.
Personal Computer
2.
Mini Computer
3.
Main Frame Computer
4.
Super Computer
5.
Workstation
Personal computer:
PC
computer is called personal computer .It maintain the work of hardware and software components. It can be
defined like as a small in which range
up to the limited pounds. It appeared in world in the year of 1970’s that work with small CPU
for programs .It use RAM and memory
chips. It is useful for word processing,
accounting, desktop, database management applications and etc. Number of
home users use this software for entertainment like play games and learn
anything from internet easily.
Personal computer have several kinds of computers such as following.
- Notebook
- Tower computer
- Laptop
- Subnotebook
- Handhel
- Plamtop
- PDA
Mini Computer:
Mini
Computer is a type of computer .It is a midsize of computer useful in work stations that can
cover 200 users simultaneously in time duration .
Workstation:
It designs for engineering applications like (SDLC and various kinds of applications
with moderate power and graphic technologies). It generally maintains high
storage media capacity along with large RAM. Workstation only work by the UNIX and Linux operating systems. It
has several types of storage media that maintain both disk drive workstations and diskless.
Supercomputer and Mainframe:
Supercomputer is best and fastest computer in world that is very expensive become . It work based on mathematical calculations very fast so, everything work well with simple procedure. Supercomputers deals with.
- scientific simulations
- animated graphic
- electrical designeperform dynamic calculations .
