Comparison of Different Computer Systems
The speed
and the storage capacity of computers are always increasing. Students should
concentrate on the comparison rather than the actual figures. For example, the
difference of hard disk storage capacity of the four types of computer systems
is not clearly cut nowadays.
| Types | Speed | Hard Disk Storage Capacity |
| Microcomputer | Below 3 GHz | Below 60 GB |
| Minicomputer | 3 – 10 GHz | Below 100 GB |
| Mainframe Computer | 10 – 100 GHZ | Around 100 GB |
| Supercomputer | Over 100 GHz | More than 100 GB |
