Classification of computers on the basis of work
Computers can be classified into various categories depending on the work tend to perform and they are as follows:
Analog Computers: Analog computer is one that measures physical values, such as temperature or pressure. We have seen different devices used as analog device. Speedometer, Milometer, Millimeter etc are some of the analog devices. Analog computers are mostly used by the government or big institutions so as to facilitate their member with all the possibilities they can. Analog computers are used for process control in industries also.
Digital Computers: A digital computers performs its functions on the basis of counting of numbers or digits. Digital computer does not measure the analog tasks. It does not show the pressure also. Digital computers function by counting the digits (0 and 1). The general concept of computers is related to digital computer.
Hybrid Computers: Hybrid computers are capable of performing both analog and hybrid tasks. It has the good quality of analog computers including hybrid computers. The analog signal may be transferred in digital which is shown on the monitor attached with the computer. Such computers are used in hospitals, jet engines, etc. the hybrid computers attached to the jet planes does the automatic tasks i.e. it helps the pilots to fly aero planes at any time without any coincidence.
Classification of computers on the basis of size: Computers can be classified into various sizes depending on its look or appearance and they are as follows:
Super computer: Super computer possesses all the computer capabilities. Such computers are used in research institutes, scientific researches, etc. These computers are massive and have huge processing speed as well as control capabilities. Till now it is the most powerful, efficient, reliable computers ever invented.
Mainframe computer: Like super computers mainframe computers also consist of huge storage unit and processing capabilities. These computers consists central processing unit (C.P.U), tape units, hard disks, card readers, many visual display units, etc. These computers are mostly owned by the government, agencies, universities, research centers, etc to carry out their various tasks or researches. These computers also consist of various work stations.
Mini computers: Mini computers are medium in size. Mini computers may have many terminals or work stations. In LAN mini computers are widely used. Mini computers typically serve many users. Mini computers are much faster than micro computers but the processing capabilities of newer micros surpass the capability of early minis.
Micro computers: Micro computers are the most common computers today and these computers are based on microprocessors. Latest micro computers are very fast indeed. The size of the micro computer may vary from small desktop size to a laptop size. In spite of being small they are capable of performing heavy task and this characteristic has made these computers very popular. These computers are user friendly than any other computers because being small in size it can be carried to the desired places easily where the people demand. Laptop and palmtop computers can be taken as an example which most of the people prefer. In the future there is a high probability that micro computer will surpass all the computers and will be able to perform each and every tasks.
