A computer network is a system of interconnected devices that communicate with each other to share resources, exchange data, and enable communication. These networks can be as small as a local area network (LAN) in a home or office or as large as the global Internet.
A data communication system refers to the infrastructure and protocols that facilitate the transfer of data between devices in a network. It involves various components such as transmitters, receivers, communication channels, and protocols that ensure reliable and efficient data transmission.
Modern advancements like 5G, IoT (Internet of Things), and AI-driven network management continue to enhance the efficiency and capabilities of computer networks and data communication systems.
