Data Communication refers to the exchange of data between two or more connected computers or devices. It involves the transfer of data from one point to another over a network, ensuring accurate and instant information dissemination.
A Local Area Network (LAN) connects individual computer terminals or nodes within a limited area using various media like coaxial cables, optical fibers, or standard telephone lines. Typically set up for businesses, schools, or within single buildings, LANs facilitate faster computing, collaboration, and communication.
Serial transmission refers to the process of sending data one bit at a time over a single wire or communication channel. It is commonly used to link computers to terminals, microcomputers to printers, and various other devices, especially those that operate at relatively slow data transfer rates.
