Local area network.
In computer terminology, LAN stands for Local Area Network. A LAN is a network of computers and other electronic devices that covers a small area, usually within a single building or a group of nearby buildings. This could be a home, office, school, or a group of buildings situated close to each other.
The primary purpose of a LAN is to allow the sharing of resources and information in a limited geographic area. These resources may include devices like printers or scanners, files, or even an internet connection. Computers within a LAN can communicate and share data directly with each other, offering a secure and fast means of communication.
LANs use various connection methods, such as Ethernet cables or Wi-Fi signals, and often operate via a central hub or switch. Each device on a LAN is known as a node, and each node has a unique address to identify it on the network.
The design and structure of a LAN can vary significantly based on the specific requirements of the users. It can be as simple as two computers connected in a home office, or it could involve hundreds of devices spread across an entire building complex in a corporate setting.
While LANs are limited in geographic scope, they form the basic building blocks of larger networks, including metropolitan area networks (MANs) and wide area networks (WANs). LANs are crucial for seamless and efficient local data transfer in a multitude of settings.
