CLASSIFICATION OF COMPUTERS
Computers in general can be classified into two major categories based upon the following criteria.
a). According to the logic used by the computer
b). According to the size of the computer.
LOGIC USED BY COMPUTER :
Computers can classify into three categories based upon logic used. They are:
a). ANALOG COMPUTERS: These are the computers, which operate on the principle of creating a physical analog of mathematical problems. These computers continuously measure physical variables. These computers used signals as input, which can come from devices like thermometers, speedometers, barometers etc. These signals are continuous flow of physical quantities.
Ex: Temperature, speed, pressure etc.
Which vary continuously. The result given by these computers usually is not very precise, accurate and consistent.
b). DIGITAL COMPUTERS: These are the computers which accepts digits and alphabets as input, which are used for solving, controlling any problem which can be expressed mathematically. These computers take data inform of zero's and one's.
c). HYBRID COMPUTERS: As any hybrid is combination of best qualities of the available types, so that it becomes the best by adopting best qualities of given variety of objects. The hybrid computers are those computers which adopt the best qualities of digital and analog computers. Thus becoming capable to work on analog or digital data. These computers are mostly used for automation of various complicated physical processes and machines.
