Computer Communication Networks refers to a system of interconnected computers and other devices that facilitate the exchange of information and resources. It is a network infrastructure that enables communication, data sharing, and collaboration between different devices located in various physical locations.
These networks utilize a variety of hardware and software components to establish reliable and efficient communication channels. They can be classified into various types, including local area networks (LANs), wide area networks (WANs), and the internet. LANs are typically used to interconnect devices in a limited geographic area, such as a home or office, while WANs connect devices over larger distances, often across cities or countries. The internet, on the other hand, is a global network that allows communication between devices worldwide.
Computer Communication Networks employ various protocols, such as Ethernet, TCP/IP, and wireless protocols, to enable data transmission and reception. They also rely on networking devices, such as routers, switches, and modems, to establish connections, direct traffic, and manage data flow.
These networks play a critical role in facilitating information sharing, enabling remote access to resources, and supporting applications and services like email, file sharing, video conferencing, and web browsing. They are essential for organizations to connect their employees, departments, and systems, as well as for individuals to access information, communicate with others, and engage in various online activities.
