Microcomputers

They are the smallest and least expensive

general purpose computers. They have
comparatively small memory and less
processing power. Physically smaller and
fewer peripherals can be attached to

them. These are commonly known as PC
or Personal Computers . They became
popular in 1970s and 80s with the

invention of the micro-processor chip.
These personal computers were cheaper

computer alternatives to more expensive
and centralised minicomputers. Thus, Microcomputer
PC’s were now affordable for offices and other smaller networking environments. By

mid 1990s PC’s were very common in offices and homes.
Innovations in last decade of 20th century and first decade of 21st century led to the

development of even smaller computers. With the advent of the technology, the size of
computer is getting even smaller.

Personal computers are of following types:

Desktop Computers

A desktop computer is a personal computer
designed for regular use at a single location on or
near a desk or table due to its size and power
requirements.

Desktop
Mobile Computers

These are exactly what they sound like–computers that are super small and mobile. A
desktop computer is mobile if you need it to be, but mobile computers usually

describe computers that are meant to be carried around and taken from place to
place. If a desktop computer is a microcomputer, then a laptop is a mobile computer.
