What term describes a network transmission from a source host to a single destination host?

• A. Unicast
• B. Broadcast
• C. Multicast
• D. Anycast

Answer: (A)

Unicast describes a network transmission sent from one source to a single, specific destination. In IP networks, each unicast packet carries a distinct destination address and is delivered along a path to that one host only, so the data reaches exactly one recipient. By contrast, broadcast goes to all hosts on the local network segment, multicast targets a defined group of receivers, and anycast delivers to the nearest member of a group of potential receivers. Because the scenario specifies one sender and one receiver, unicast is the appropriate term for this type of transmission.
