digits is called a bit. The information is represented in digital computer in
groups of bits.
Hybrid Computers
It is a combination of analog computers used in
continuous system also, non-linear discrete
features of a digital computer such as storing values
logical operations and switching. These computers
are mostly used with process control equipment in
continuous production plants like all refineries etc.
and used at places where signals as well as data are to be entered into
computer. Areas of application–nuclear power plants, mines etc.
Classification Based on Size and Processing Power
The following are the classification of computer based on size and processing
power:
Super Computers
These are very large and powerful computers
that are roomed to all sizes. This type of
computer is typically used for scientific and
enginering applications to design weapons,
weather forecasting, biomedical analysis,
research and aircraft design.
Mainframe Computers
Mainframe computers are capable of processing
data at very high speeds – hundreds of million
instructions per second. They are large in size.
These are used to process large amount of data
quickly. Some of the obvious sector in which
mainframe computers are used– banks, airlines
and railway reservation systems, etc.
