sarjaliikenneyhteyksiä

Sarjaliikenneyhteyksiä refers to serial communication connections used in data transmission. These connections transmit data one bit at a time over a single communication line or a shared pathway. Unlike parallel communication, which sends multiple bits simultaneously, serial connections are simpler and require fewer wires, making them advantageous for longer distances and cost-effective designs. Common examples of serial communication protocols include RS-232, USB (Universal Serial Bus), and Ethernet. RS-232 was historically prevalent in computer peripherals and industrial equipment. USB has become the ubiquitous standard for connecting a vast array of devices to computers, from keyboards and mice to external storage and printers, offering both data transfer and power. Ethernet is the dominant wired networking technology for local area networks (LANs), enabling communication between computers and other network devices. The choice of serial connection type depends on factors such as required data transfer speed, distance, and the specific application. Key characteristics of serial communication include synchronization mechanisms to ensure data integrity and often the use of start and stop bits to delineate data packets. Despite its sequential nature, modern serial technologies achieve very high speeds, making them essential for a wide range of digital applications.
