Basics of Computer Network

Data communication and computer networks are fundamental to modern technology, enabling seamless information exchange between devices. Essentially, a computer network connects two or more computing devices through various communication technologies. Businesses leverage these networks – whether using wired connections like cables or the internet – to access shared resources like servers, collaborate on programs, and share files and information efficiently.

Data communications (DC) is the process of transferring digital data between locations using computing and communication technologies. This includes moving electronic or digital data between two or more nodes, irrespective of their physical location, the technology used, or the data itself. At its core, data communication involves transmitting digital data between computers and within a computer network or data network. A computer network itself is a telecommunications network designed to facilitate data exchange between computers. Data communication relies on one or multiple transmission mediums to connect devices within a communication system comprised of both hardware and software.
