Sisendiväljund

Sisendiväljund, often abbreviated as I/O, refers to the communication between a computer system and the outside world. This includes both sending data out from the system (väljund) and receiving data into the system (sisend). The "outside world" can encompass a variety of devices and entities.

Input devices are the tools through which data is entered into a computer. Common examples include keyboards, mice, microphones, scanners, and touchscreens. These devices translate physical actions or analog signals into digital information that the computer can process.

Output devices, conversely, are used to present the results of a computer's processing to the user or another system. Displays (monitors), printers, speakers, and projectors are typical output devices. They convert digital data into a format that humans or other machines can perceive, such as visual images, sound, or printed text.

The process of sisendiväljund is fundamental to the operation of any computing device. Without it, computers would be isolated systems unable to interact with users or other technologies. The efficiency and speed of I/O operations can significantly impact overall system performance. Modern computing relies on a vast array of interfaces and protocols to manage the constant flow of sisendiväljund.
