Computer categories describe the
relevant computing power of different
makes of computer systems.
However, this division is not hard and
fast. Rather many categories overlap
others in many regards
Micro Computer Systems
Also known as Personal computers or PCs.
These are the smallest computer systems.
Microcomputers could be use in networking due
to their more processing powers.
Mostly single owner entity therefore could be use
for variety of personal and business tasks.
Desktop computers could be placed on top of a
table (desk), as they are reduced in size.
Portable computers that includes
Laptops, Notebook etc. can be taken anywhere with
a person while traveling.
Mini Computer Systems
Also known as Midrange Computer Systems.
Larger than Microcomputers.
More powerful than micro computers.
Cost Less to Buy and Maintain than Mainframe
Less powerful and costly than mainframe computers.
Need No Air-conditioning.
Many Applications like scientific, engineering, industrial
Popular Network Servers i.e. we may use them as
servers in networks.
Mainframe Computer Systems
Large, powerful Computers.
Larger than Micro and Mini Computers.
More Expensive than micro and mini computers.
Large Memory Storage.
Accommodate Many Users (Hundreds or Thousands
same time (simultaneously).
Large Organizations use Mainframes.
Popular Network Servers
Excellent Database Servers.
The Most Powerful Computers.
Can process Thousands of MIPS
