Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings.
Generally, some of the network devices or equipments used in a local area network (LAN) are an access point, personal computers, a switch, a router, printer, etc.

Answer:
Port number is used at the transport layer to identify the receiving application
Explanation:
Transport layer is responsible for overall “end-to-end” communication. It provides communication service to the application process which might be running on “different hosts”.
TCP (Transmission Control Protocol) or UDP (User Data Protocol) is the protocol used in the Transport layer. The port number is essential so that the transport layer can carry packets to the right destination pointing to the right application.
A port number usually contains 16 bit integer. Normally this number will send along with the header. Port number plays a major role in Transport layer.
