Sisendväljundit

Sisendväljundit, often abbreviated as I/O, refers to the communication between an information processing system, such as a computer, and the outside world. This outside world can be a human operator, another computer system, or a peripheral device. The process involves the transfer of data, either into the system (input) or out of the system (output).

Input devices are used to send data to the processing system. Examples include keyboards, mice, scanners, and microphones. These devices convert physical actions or analog signals into digital data that the computer can understand and process.

Output devices are used to present the results of the processing system to the outside world. Common output devices are monitors, printers, speakers, and projectors. They translate digital data from the computer into a format that humans or other systems can perceive, such as visual images, sounds, or printed documents.

The management and control of these input and output operations are crucial for the efficient functioning of any computing system. Operating systems play a significant role in handling I/O requests, managing device drivers, and ensuring that data is transferred correctly and efficiently between the central processing unit, memory, and the various peripheral devices. Sophisticated techniques are employed to optimize I/O performance, as it can often be a bottleneck in overall system speed.
