Local area networks, or LANs, were created in the 1960s for use by colleges, universities, and research institutions, largely to connect computers to one another. It allows computers to share files, print, and be viewed and controlled by one another using a single internet connection. LANs are now used in restaurants, coffee shops, and even our homes, in addition to businesses and schools. The variety of devices that can be linked to a LAN have been substantially broadened thanks to wireless communication. Smart TVs, stereos, speakers, lighting, thermostats, window shades, door locks, security cameras, and even tiny appliances like coffeemakers, refrigerators, and toys are all examples of modern technology.
A local area network (LAN) is made up of cables, access points, switches, routers, and other components that allow devices to connect to internal servers, web servers, and other LANS over a wide area network. Virtual LANs emerged as a result of the introduction of virtualization, which allows network administrators to conceptually organize network nodes and segment their networks without requiring large infrastructure changes. For example, there are two computers for a separate department, each department’s computers can be connected to the same switch, but it will function as if they are separate.
