Hybrid: A hybrid computer is a special type of computer that combines
features of both digital and analog computers. It uses the speed of
an analog computer and the accuracy of a digital computer. These
computers are generally used in scientific research and specialised
applications. The heartbeat measuring machine used in hospitals is the
most common example of a hybrid computer.
A Hybrid Computer
Purpose
On the basis of their purpose, computers can be of two types:
General Purpose Computer: A general-purpose computer is a type of computer that can
perform many different tasks equally well. This includes personal computers like desktops,
laptops, smartphones, and tablets. They are designed to handle a wide range of jobs efficiently.
Special Purpose Computer: A special-purpose computer is designed to do a specific job very
quickly and efficiently. It can't do other tasks. These computers are used for specific functions,
like controlling machines in factories or predicting the weather.
Size, Speed, Processing Power and Cost
Computers differ in size, processing power, speed, and cost. On the basis of these factors,
computers can be categorised as follows:
Microcomputer
A microcomputer is a small type of computer that uses one microprocessor as its main 'brain' for
processing information. It is a small and less expensive digital computer. This type of computer
is made for one person to use at a time. A microcomputer is also called a Personal Computer
(PC). Some examples of microcomputers are:
Desktop: It is a personal computer developed for regular use and
generally placed in a single location on a desk or a table. All its
components, such as a keyboard, mouse, and storage devices, are
connected through wire or without wire. Due to its size and power
requirements, we cannot carry this type of computer. Desktop
computers are generally used in schools, colleges, offices, etc. Desktop
Laptop: A laptop is a small and portable personal computer that
you can use while traveling. It's designed to fit on your lap, and it
has a built-in screen, keyboard, and mouse. You can use a laptop
anywhere because it has a rechargeable battery that allows it to
work without being plugged into power for 4 hours or more. People
like marketing executives who travel a lot often use laptops.
Laptop
Tablet: A tablet is a small and portable digital computer that is smaller
than a laptop. Instead of a mouse, it has a touchscreen as its input
device. Like a laptop, it has a rechargeable battery. Tablets usually have
fewer features than laptops. They are often used by professionals in
different organisations.
