A Local Area Network (LAN) is a connectivity system that links computers and devices within a limited area, such as a company's building or campus. It offers high-speed data transfer, enabling efficient communication and resource sharing, including printers and internet access. With robust security measures and centralized management, IT administrators can maintain and protect sensitive data effectively. LANs foster collaboration among employees through shared applications while remaining cost-effective and easily scalable as a business grows. Ultimately, a LAN serves as the backbone of modern workplaces, enhancing productivity and streamlining operations.
