What is a elements of Computers system ?
Computers can be classified into two categories.
(a) Classification according to the Logic units.
(b) Classification according to Size.
Classification according to the Logic Units.
Analog Computeres
These computers recognize data as a continuous measurement of a Physical property. Their output is usually in the form of reading on dials or graphs. Voltage, P[ressure, speed and temperature are some physical properties that can be measured in this way.
Example
(a) A services Station gasonline pump contain an analog processor that connects fuel flow measurement into quality and price values.
(b) Automobile speed meter, etc.
DigitaL Computers
These are high speed programmable electronic device that perform Mathematical calculation compare value and store the results. They recognize data by counting discrete signals representimg either a high { on } or low { Off } voltage state of state of electronic. Numbers, alphabets and special sysbols can all be reduced to representation by 1s and 0s.
example
(a) Personal Computers
(b) Score board that directly counts discrete value such as the time left to play and the score of each team.
Hybrid computers
Hybrid Computers combine the beast features of analog and Digital computers. They have the speed of analog computers and the accuracy of the digital computers. They are usually used for special problems in which input data derived from measurements are converted into digits and processed by computers.
