A local area network (LAN) is a computer network that connects devices within a limited area, such as a home, office, or small group of buildings. A LAN may be wired, wireless, or a combination of both. The devices on a LAN can be connected using cables, such as Ethernet cables, or wirelessly through technologies such as Wi-Fi.
A wide area network (WAN) is a network that connects devices over a large geographical area, such as a city, country, or even across multiple countries. WANs can be used to connect LANs together, allowing devices on one LAN to communicate with devices on another LAN. WANs can be established using various technologies, such as leased lines, satellites, or the internet.
In general, LANs are used for connecting devices in a small area, while WANs are used for connecting devices over a larger area.
Local Area Network
A local area network (LAN) is a computer network that connects devices within a limited area, such as a home, office, or small group of buildings. Devices on a LAN can be connected using cables, such as Ethernet cables, or wirelessly through technologies such as Wi-Fi.
One of the main benefits of a LAN is that it allows devices to communicate with each other at high speeds, making it possible to share resources such as printers, file servers, and internet connections. A LAN also provides a degree of security, as it is relatively difficult for outsiders to access the network.
In a home or small office, a LAN might consist of a few computers and other devices, such as printers and routers, connected together. In a larger organization, a LAN might span multiple rooms or even multiple buildings.
There are different types of LANs, including peer-to-peer LANs, where all devices are equal and can communicate directly with each other, and client-server LANs, where one or more devices act as servers and provide resources to other devices, known as clients.
Wide Area Network
A wide area network (WAN) is a network that connects devices over a large geographical area, such as a city, country, or even across multiple countries. WANs can be used to connect local area networks (LANs) together, allowing devices on one LAN to communicate with devices on another LAN.
WANs can be established using various technologies, such as leased lines, satellite, or the internet. Leased lines are dedicated communication lines that are leased from a telecommunications provider, while satellite technology allows devices to connect to the internet through a satellite orbiting the Earth. The internet can also be used to create a WAN, by connecting devices through internet service providers (ISPs).
One of the main benefits of a WAN is that it allows devices to communicate over long distances, making it possible for people to access resources and communicate with each other no matter where they are located. WANs are often used by businesses to connect their offices in different locations, allowing employees to access company resources and communicate with each other regardless of location.
In contrast to LANs, which are usually owned and managed by a single organization, WANs can be owned and managed by multiple organizations. For example, the internet is a WAN that is owned and managed by a large number of different organizations.
