Networking definition

A networking definition can be defined as  follows, A network consists of multiple devices that communicate with one another. It can be as small as two computers or as large as billions of devices.

A local area network is limited to a specific area, such as a home, office, or campus. A home network may have a single router that offers both wired and wireless connections. For example, a computer may connect to the router via Ethernet, while smartphones and tablets connect to the router via Wi-Fi. All devices connected to the router share the same network and often the same Internet connection.

A larger network, such as the network of an educational institution, may be comprised of many switches, hubs, and Ethernet cables. It may also include multiple wireless access points and wireless repeaters that provide wireless access to the network. While this type of network is much more complex than a home network, it is still considered a LAN since it is limited to a specific location.

A wide area network is not limited to a single area, but spans multiple locations. WANs are often comprised of multiple LANs that are connected over the Internet. A company WAN, for example, may extend from the headquarters to other offices around the world. Access to WANs may be limited using authentication,
