` These vary in their computation power, speed,
memory and size.
` The smallest ones can be held in palm.
` These are known as Personal Digital Assistants(PDAs)
` When equipped with Cell phones, PDAs can
connect to Wireless Computer networks to
exchange information

` Generally used in Business and at home for word
processing, entertainment, communication and
other applications.
` Have a large amount of storage so as to storethousands of programs and documents
` Consists of Desktops and Laptops.
` Laptops are more compact in size and have less
weight.

` Same as Personal computer but have large
memory and more mathematical abilities.
` Specially found in scientific, industrial fields which
require high levels of computational power.` Often have very high resolution and accelerated
graphics handling capabilities which make them
suitable for advanced architectural design work.

` Very powerful computers.
` Number of personal computers and terminals can
be connected to the server.
` Have a very large disk storage and RAM` Can have more than one processor
` Computers connected to the server are called
clients.
` This is known as client-server architecture.

` Were used to control machines in manufacturing
units.
` Defined as small general purpose computer that has
computing power larger than that of microcomputers.` Can support simultaneous working of up to 100 users
and is usually maintained in business organizations
for the maintenance of accounts and finances.

` Computers used by large organizations involved inmeteorological surveys and statisticalmathematics.
` They are designed for handling huge amount ofdata and information.
` Have great processing power and very largestorage capacity as compared to mini computers
` Core computers which are used for desktop
functions of over 100 hundred userssimultaneously.

` Somewhat similar to mainframe computers and
are used in economic forecasts and engineering
designs.
` These are the largest and fastest computers.` Consists of several processors running together
there by making them immensely faster and
powerful.

` Almost an extinct type of computer. It is different
from digital computers in respect that it can
perform numerous mathematical operations
simultaneously.` Utilizes mechanical, hydraulic or electrical energy
in operation

` These type of computers are, as the name
suggests, a combination of best features of analog
and digital computers.
` They have the speed of analog computers andaccuracy of digital computers.
