Session is defined as what in networking?

• A. A time-limited password exchange
• B. A virtual connection between two hosts by which network traffic is passed
• C. A single message sent between processes
• D. A physical wire between devices

Answer: (B)

A session in networking is the ongoing, stateful interaction between two endpoints that allows data to be exchanged over a logical connection. It’s a virtual link established for communication, managed with control information and state so multiple messages can flow in an organized way during the encounter. That’s why the best description is a virtual connection between two hosts by which network traffic is passed—because it emphasizes the established, ongoing dialogue rather than a physical medium, a single message, or an authentication step. A physical wire is just a link, not an interaction with state; a single message isn’t enough to constitute a session; and a time-limited password exchange describes authentication rather than the sustained data exchange that a session enables.
