A Local Area Network (LAN) is a group of computers and devices connected within a limited area, such as a home, school, or office. It allows these devices to communicate and share resources, like files and printers, efficiently. LANs typically use wired connections, like Ethernet cables, or wireless connections, such as Wi-Fi. LANs are essential for enabling collaboration and resource sharing among users in close proximity. They can support various devices, including computers, smartphones, and printers. By using a LAN, users can access the internet and share data quickly and securely within their local environment.
