Detailed explanation-1: -A network that connects computers and devices within a building or small group of buildings is known as a local area network (LAN). A LAN may link the computers within a home, office, or campus, for example, allowing the individual users to share resources.
Detailed explanation-2: -A local area network connects devices within a relatively close proximity. A LAN can be deployed inside a home, office suite, building or corporate campus.
Detailed explanation-3: -A LAN is an interconnected system limited in size and geography. It typically connects computers and devices within a single office or building. It is used by small companies or as a test network for small-scale prototyping.
