How does a computer network work Specialized devices such as switches, routers, and access points form the foundation of computer networks. Switches connect and help to internally secure computers, printers, servers, and other devices to networks in homes or organizations. Access points are switches...
In computer networks, hubs serve as central connection points within a network, allowing devices to communicate and share data. Operating at the physical layer of the OSI model, hubs transmit data signals to all connected devices, regardless of the intended recipient. By exploring what is a hub...
Typically, computer networks are defined by geographical area. A local area network (LAN) connects computers in a defined physical space, while awide area network(WAN) can connect computers across continents. However, networks are also defined by the protocols they use to communicate, the physical...
A wide area network (WAN) is a large computernetworkthat connects groups of computers over large distances. WANs are often used by large businesses to connect their office networks; each office typically has its own local area network, orLAN, and these LANs connect via a WAN. These long conn...
