sarjaviestintäprotokolla

Sarjaviestintäprotokolla, also known as serial communication protocol in English, refers to a method of transmitting data between two or more devices in a sequential manner, one bit at a time, over a single communication line. This is in contrast to parallel communication, where multiple bits are transmitted simultaneously over separate lines.

The primary function of a serial communication protocol is to define the rules and conventions that govern how data is exchanged. This includes aspects like the order of bits, the timing of transmission, the use of start and stop bits to frame each data unit, and error checking mechanisms. Common examples of serial communication protocols include RS-232, USB (Universal Serial Bus), and SPI (Serial Peripheral Interface).

RS-232 is a widely used standard for serial communication, particularly in older computing systems and industrial equipment. USB has become the dominant standard for connecting peripherals to computers and other devices, offering higher speeds and plug-and-play capabilities. SPI is a synchronous serial communication interface commonly used for short-distance communication, often within embedded systems.

Serial communication protocols are essential for a vast range of applications, from connecting keyboards and mice to computers to enabling communication between microcontrollers and sensors in embedded systems. Their simplicity and efficiency make them a fundamental technology in modern electronics and computing.
