These devices prove to be of great use in recognizing characters in question sheets, enrolment forms, registration forms, employee payroll, etc.

Some of the commonly used pointing devices are: Modern computer systems use bit data buses for data transfer.

A standard keyboard consists computets the following groups of keys: Breaking down the instruction into different parts, so that it can be easily understood before being processed by the CPU.

The DRAM needs to be continuously refreshed with power supply because the capacitor has the tendency to get discharged. The fastest type of computer that can perform complex operations at a very high speed.

It also consumes a lot of power and produces a large amount heat. The plotters were used as a substitute to the colored printers when the printers were very expensive and were also not capable of drawing bigger images such as graphs.


Depending upon the form of output required, the output device fundammentals belong to one of the following categories: We can provide the input to a computer in two ways: Memory and Storage Systems 4. The interface unit acts as an intermediary between the processor and the device controllers of various balagurusay devices in the computer system. DRAM retains the data for a very short span of time, even after the power supply is bwlagurusamy off.
