• A computer is on electronic device that
helps people perform different tasks.
The four types of computers include:
1) Microcomputers or Personal Computers
2) Mini Computers or Portable Computers
3) Mainframe Computers
is generally a synonym for the more common term
personal computer or PC, a computer designed for an
individual. It uses microprocessor technology to input,
manipulate, store and output data,
Businesses use personal computers for word processing,
accounting and desktop publishing and for running
spreadsheet and database management applications. At
home, the most popular use for personal computers is for
Two Classifications of
1. Personal Computer or PC
2. Portable Computer
It have become widely popular with
people of all lifestyles because they are
powerful, affordable and easy to use.
Personal 'computers are of various
sizes and design.
These include laptop or sub-notebook, tablet
computer and personal digital assistants.
They are small enough 10 move easily from
one place to another and they can operate on
batteries. They are popular with people who
travel and need computing power on the go.
Laptop / Notebook Computer
A small, portable computer - small enough that it
can sit on your lap. Nowadays, laptop computers
are more frequently called notebook computers.
Aside from size, the principal difference between
a notebook and a personal computer is the display
screen. Notebook computers use a variety of
techniques, known as flat panel technologies, to
produce a lightweight bred non-bulky display
This provides the full power and functionality of today's
notebook PCs. With a tablet PC, you can use your
computer more often and in more situations than ever
before - at your desk, in the hallway, in a meeting room,
on the manufacturing floor, in a client's office or on room,
Long battery life arid light weight make the Tablet PC
more mobile than current notebook PCs. The streamlined
designs make the tablet PC less obtrusive to use when
you are in a meeting or working away from your desk.
Microsoft's Tablet PC
is a design for a fully-equipped personal
computer that allows a user to take notes
using natural handwriting on a stylus - or
digital pen-sensitive touch screen instead of
requiring the use of a keyboard. The Tablet
PC is similar in size and thickness to a
yellow paper notepad. It will run existing
Windows-based applications and is
intended to be the user's primary personal
computer as well as a note-taking device.
A midsized computer. In size and power,
minicomputers lie between workstations and
mainframes. In general, a minicomputer is a
multi-processing system capable of supporting
from 4 to about 200 users simultaneously.
A very large and expensive computer capable of
supporting hundreds or even thousands of users
simultaneously. In the hierarchy that starts with a
simple microprocessor at the bottom and moves to
supercomputers at the top, mainframes are just
below supercomputers. In some ways, mainframes
are more powerful than supercomputers because
they support more simultaneous programs.
This is the fastest type of computer.
are very expensive and are employed for
specialized applications that require immense
amounts of mathematical calculations, For
example, weather forecasting requires a
supercomputer. Other uses of supercomputers
include animated graphics, fluid dynamic
calculations, nuclear energy research and
