Syöttötulostusliitännät, often abbreviated as I/O (Input/Output) interfaces, are the hardware and software mechanisms that allow a computer system to communicate with the outside world. These interfaces enable data to be transferred into the system (input) and out of the system (output). They are fundamental to the operation of any computing device, as they connect the central processing unit (CPU) and memory to peripherals such as keyboards, mice, displays, printers, and storage devices.

Input interfaces capture data from external sources. For example, a keyboard sends character data to the computer through an input interface, while a mouse transmits cursor position data. Output interfaces, on the other hand, transmit data from the computer to external devices. A display receives image data through an output interface, and a printer receives document data for printing. Many interfaces function as both input and output, allowing for two-way communication.

The design and functionality of I/O interfaces vary widely depending on the type of peripheral and the desired performance. Common examples include USB (Universal Serial Bus), which is a versatile interface for a wide range of devices; HDMI (High-Definition Multimedia Interface), used for audio and video transmission; and Ethernet, used for network communication. Each interface has specific protocols and physical connectors to ensure proper data exchange. Software drivers play a crucial role in translating data between the operating system and the hardware interface, making the communication process seamless for the user. Efficient I/O interface design is critical for system performance, as slow or inefficient interfaces can create bottlenecks that limit the overall speed of the computer.
