LANs connect workstations, peripherals, terminals, and other devices in a single building or other geographically limited area. Types of peripherals connected to a LAN.Topologies: Physical arrangement of network nodes and media within an enterprise networking structure.Network interface card. Board that provides network communication capabilities to and from a computer system. Also called an adapter.Repeater:Device that regenerates and propagates electrical signals between two network segmentsTwo common internetworking problems are too many nodes, or not enough cable. If either of these problems exist, a repeater provides a simple solution.HUB:Generally, a term used to describe a device that serves as the center of a star-topology network.Switch:1.) Network device that filters, forwards, and floods frames based on the destination address of each frame. 2.) General term applied to an electronic or mechanical device that allows a connection to be established as necessary and terminated when there is no longer a session to support.Device that uses one or more metrics to determine the optimal path along which network traffic should be forwarded. Routers forward packets from one network to another based on network layer information. Occasionally called a gateway.In order for reliable communications to take place over a network, data to be sent must be put in manageable traceable packages. This is done through the process of encapsulation. When the data is transmitted on just a local area network, we talk about the data units as frames, because the MAC address is all that is necessary to get from source to destination host. But if we need to send the data to another host over an Intranet or the Internet, packets become the data unit that is referred to. This is because the Network address in the packet contains the final destination address of the host the data (packet) is being sent to.1. Linksys 4-Port Router2.
