Features Input And Output Devices

One of the basic functions of the computer is communicating with external devices, ie, the computer must be able to send and receive data from this device. Without this feature, your computer would not be operational because their calculations would not be visible from the outside.
There are a variety of devices that can communicate with a computer, from the classic devices (terminals, printers, disks, tapes, etc.) To A / D and D / A for measurement and process control.
Of all the possible peripherals, some are reading, other languages and other reading and writing (it is important to emphasize that this fact is always viewed from the standpoint of the process.)
Moreover, storage peripherals are also called auxiliary memory or mass.
Most peripherals are composed of a mechanical part and other electronics. These parties usually clearly separated to provide greater modularity. The electronic component is often referred peripheral device driver or, alternatively, the device adapter. If the device has no mechanical parts (for example, the screen of a terminal), the driver will be formed by the digital part of the circuit. Often the device drivers are housed in a printed circuit board separately from the rest of the peripheral.
In this case it is quite common that a single controller can serve similar devices.
The main problem is its peripherals variety also affects the speed of transmission. Therefore, the biggest drawback we found in the peripheral is the difference between their rates of transmission and the difference between them and the operating speed dla computer.
