What type of packet delivery occurs within the same LAN?

In a Local Area Network (LAN), unicast delivery is a method of transferring packets where the data is sent from a single sender to a single receiver. This means that each packet contains the address of one specific device on the network, ensuring that only that designated device receives the transmitted information.

Unicast is the most common form of communication within a LAN as it allows devices to communicate point-to-point. For instance, when a computer sends a file to another specific computer within the same LAN, it uses unicast communication. This method is efficient for direct communication between two devices and is essential for applications like file transfers, web browsing, and other direct client-server communications.

In contrast, other delivery methods serve different communication needs. Broadcast delivery sends data to all devices in the LAN simultaneously. Multicast delivery allows data to be sent to multiple specific devices that have joined a multicast group, while anycast delivery directs data to the nearest device in a group of potential receivers. These methods have their place but do not provide the same point-to-point communication that unicast does within a LAN.
