What are the uses of LAN with respect to current practice?

Local Area Networks (LANs) are widely used in various settings, including homes, offices, and educational institutions, for facilitating high-speed data transfer and resource sharing among connected devices. They enable users to share printers, scanners, and internet connections, enhancing collaboration and productivity. Additionally, LANs support local file storage and management, allowing for efficient access to shared data. With the rise of IoT devices, LANs also play a crucial role in connecting smart devices, enhancing automation and control in various environments.
