Bot GPT 3.5 A. A LAN (Local Area Network) is a computer network that covers a small geographic area, such as a single building or a campus. It allows multiple devices to connect and communicate with each other within a limited area.
B. The purpose of a LAN in an organization is to facilitate communication and resource sharing among devices within the network. This can improve efficiency, collaboration, and productivity by allowing users to access shared files, printers, and other network resources.
2. Three components of a LAN and their purposes or functions are:
a. Switches - Switches are crucial components of a LAN as they connect devices within the network and direct data traffic efficiently. They help in creating a secure and reliable network by filtering and forwarding data packets to the intended destination.
b. Routers - Routers are used in LANs to connect multiple networks together, such as connecting a LAN to the internet. They determine the best path for data packets to travel between different networks and help in managing traffic flow.
c. Network Interface Cards (NICs) - NICs are hardware components that allow devices to connect to a LAN. They provide the necessary physical connection and communication between the device and the network. NICs also help in translating and transmitting data between the device and the network.
