CLASSIFICATION  OF DIGITAL COMPUTER

Computer are classified under a number of factors.Some people classify them according to their processing speed.main memory,technology used in production,axuillary storage capacity and cost.

The major classification are:

b)   Mainframe Computer,

c)   mini computers

d)   Micro computers

Super Computers: They are the most powerful  and expensive computers. They can execute about sten million instructions within a second and support a very large number of applications or users at  a time.

Mainframes : they are large scale computers  often located in business. Financial and research institutions. They process and store a very large amount  of data an dinformation. 

They can also play host to a large number of say 1000 workstations

Mini frames : they lie between micro and main frame computers in terms of cos, processing speed and the volume of applicatins. They are very powerful in operation

They can perform  many tasks which formely could be performed by the main frame only.

The mini frame computer is not very portable but can be moved more easily than the mainframe.
