Chapter Profile
Hybrid Computer refers to a computer that provides the
functionality of both an analog and a digital computers while
processing and displaying data. It uses the speed of analog
computer and accuracy from digital computer. Heart beat
measuring machine used in hospital is the common example of
the hybrid computer.
Hybrid Computer
Size, Speed, Processing Power and Cost
Computers differ in their size, processing power, speed and cost. On the basis of these factors,
computers can be categorised as follows:
Microcomputer
A microcomputer is a type of computer that has one microprocessor as its processing unit. It is a
small and less expensive digital computer. This type of computers are made to be used by single
user at a time. Some examples of microcomputer are:
Desktop: It is a personal computer developed for regular use and
generally placed at a single place on a desk or table. All its components
such as keyboard, mouse and storage devices are connected through
wire or wireless. Due to its size and power requirements, we cannot
carry this type of computers. Desktop
Laptop: It is a portable and small digital personal computer that is
suitable for use while travelling. We can use a laptop computer by
keeping it on our lap. A laptop computer has a built-in mouse, monitor
and a keyboard. It also has a rechargeable battery.
Laptop
Tablet: It is a portable digital computer smaller than the laptop
computer. It has a touchscreen as its primary input device instead of
mouse.
Tablet
Minicomputer
A minicomputer is type of computer that is bigger, more expensive,
and more powerful than a microcomputer. It can contain one or more
microprocessors as its processing unit. A minicomputer has the capability
to serve a number of users simultaneously.
It is also known as small or midsize server computer. Some common
examples of minicomputers are PDP-11, PDP-8, and HP-3000.
