Sarjaviestintäprotokollien
Sarjaviestintä, also known as serial communication, is a method of transmitting data between devices one bit at a time, sequentially over a single communication line. This contrasts with parallel communication, where multiple bits are sent simultaneously over multiple lines. Sarjaviestintä is commonly used for long-distance communication due to its simpler wiring and lower cost compared to parallel communication.
The two most common forms of sarjaviestintä are asynchronous and synchronous. Asynchronous communication does not require
Popular serial communication protocols include RS-232, USB (Universal Serial Bus), and Ethernet. RS-232 is a standard
