Analog computers measures and answers thequestions by the method of “HOW MUCH “.•Signals are continuous of (0 to 10V)•Accuracy 1% approximately•High speed•Output is continuous.•Time is wasted in transmission time
Digital computersDigital computers counts and answers the questions by the method of HOW MANY. The input data is represented by a number. These are used for logical and arithmetic operations. Signals are of two levels (0V or 5v) Accuracy unlimited Low speed sequential as well as parallel processing Output is continuous but obtain when computation is completed
•Micro computers are the smallest computersystem.•There size range is from calculator todesktop size.•It is also known as Grand child Computer.•Applications- Personal computer, Multiuser system, offices.
•These are small general purpose system .•They are generally more powerful and mostuseful as compared to micro computers.•They are known as Child computer.•Applications- Departmental system, Networkserver, Work group system.
•Main frame computers are those computersthat offer faster processing and greaterstorage area.•The word main frame comes from metalframes.•It is also known as Father Computer.•Applications-Host computers, Centraldata Base server.
•Super computers are those computers which aredesigned for scientific job like weather forecasting andartificial intelligence etc.•They are fastest and expensive.•It contains a number of CPU which operate in parallelto make it faster.•Application-Weather forecasting, Weapon researchand development.
•The combination of features of analog anddigital computers is called hybrid computer.•The main example are Central Defense andpassenger flight radar system.•They are also used to control the robots.
