Abstract

Computer classified based on there purpose with clear examples for the special purpose

computers there are seven examples and three examples for special purpose computer

each example have been explained clearly what it does and its already classified whether

is a general purpose of specific purpose it hardware and software part have been

discussed briefly with the. Help of diagram of each example; also be for the existence of

that particular computer what was used.

INT!"#CTI!N

Nowadays, most people knows what is computer. Computer available everywhere, everyone

uses it at home, work, university. In future, computer will be using for everything. Individual

computers means PC, they can watch movies, play games, connect to the internet to sit in

Facebook or ou!ube. "ut this is #ust one face of computer. It is much more than PC. $

computer can be defined as a machine that take s instructions and operations them.

Commanded instruction is known as programs to do operation. $t a time, user can give a few

instruction to a computer to complete %uite a lot of operations. !his is a point of difference

for the computer.

C$A%%I&ICATI!N !& C!'(#T)

&tarting with the first computer, there are different types of computer. &ome of them for

specific task and some for general users. !here are three types to classification computer

based on application, such as $nalog, 'igital and (ybrid. $nalog computer is uses the

continuously of physical phenomena like electrical, mechanical. )ostly, this computer uses

in (ospitals and $ir*crafts. 'igital is common classes of computer. It can be distinct as acomputer for calculation and logical operations. (ybrid computer is mi+ing of $nalog and

'igital computers. Computers also can be classified based on sie like )ainframe, )ini and

)acro Computers. )ainframe computer is very powerful with large memory and processing.

-ne of this computer will take many places but it can support hundreds of users at a time.

)ini is medium sied computer. It support less than )ainframe and power is also less. )icro

is computer that uses everyday by everyone. Classification can be based on brand, but

everyone knows what of brand most popular now and they are choosing between some of

them.

&pecial purpose computers are created to complete only one specific task. !hey are called

dedicated computers, because are perform one task again and again. !hese computer mostly

uses for playing graphic intensive /ideo 0ames, traffic lights control system, navigational

system in an aircraft, weather forecasting, oil e+ploration, and in automotive industries, and

obot helicopter.

!o create specific purpose computer does not need a lot of memories because they are using

to a specific issue its design as opposed. !hey are %uick in progressing than general computer

by they have only one functions. "ut weakness of this computer, they are not fle+ibility,

because cannot utilied to perform different tasks.

%mart Traffic $ight

In an era, where everyone has a car smart traffic lights is very important. It combines e+iting

technology with the artificial intelligence to create lights that can do own decision to control

traffic. !his completely differs than the normal traffic lights systems which their signalling

devices located at pedestrian crossings, road intersections and other places to control course

of traffic, they have basically signal that operate a covered induction coil to intellect the

presence of signal that regulate to information from the central computer about the position,

speed and direction of cars. 34mad I $bdul 5areem, 6117

&everal decades ago, police officer stayed on the road for driving the machine. -ver time, the

number of owners of cars increased that forcing to create traffic technology to invent road

accidents. Introduction of the system of red, yellow, and green signal was very helpful in this.

-f course there were cons of first traffic but in time all the shortcomings were removed. Now,

there is a new intelligent traffic system.

35oopman, 6687

'ain part of the smart light control system are traffic light control centre this where all

information are processed and stored sensors to send the signals and send to the control

centres and $)" light is for indication to the road users.

-eather &orecasting Computer

9eather forecasting is one of the best inventions, a breakthrough in the field of science and

technology with it can accurately determine the state of the atmosphere for a given locality.

!he computer that generates a weather forecast with the help of the meat computing and

large*scale factors such as air pressure, rotation of the 4arth, the solar radiation and the water

cycle. Forecasters can determine prognosis from all directions and not #ust at one point.

why are they used and there main part where cleared elaborated computer and e+plain how

the computer is used why is used and before there where created what was used instead.
