A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, [1] [2] [3] and has its network equipment and interconnects locally managed. LANs facilitate the distribution of data and sharing network devices, such as printers.

The first standard was published on September 30, 1980, as "The Ethernet, A Local Area Network. Data Link Layer and Physical Layer Specifications". This so-called DIX standard (Digital Intel Xerox) [18] specified 10 Mbit/s Ethernet, with 48-bit destination and source addresses and a global 16-bit Ethertype-type field. [19]
A local area network (LAN) is a network that connects computers and devices in a limited geographical area such as a home, school, office building, or closely positioned group of buildings. Wired LANs are most commonly based on Ethernet technology.
Computer network engineering is a technology discipline within engineering that deals with the design, implementation, and management of computer networks. These systems contain both physical components, such as routers , switches, cables, and some logical elements, such as protocols and network services .
The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [ 3 ] [ 4 ] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.
