A session is a logical connection between two addressable entities in the network for the mutual exchange of information. Depending on the context, there are other functions and properties associated with a session.

  1. On the Web, a session is the time a user is actively interacting with a Web page. Each session is identified by its session ID. The session begins when the user accesses the Web page and ends when he or she leaves. All intermediate activities, such as calling up images or performing transactions, belong to a session. The temporal length of the session is the session duration. The number of user sessions on a web page is a measure of the traffic to the web page. A user session can be interrupted and, when the user logs back in, is treated as a single session via the session ID.
  2. Indata transmission, a session is understood to be the duration of the connection during which the communication partners exchange data and the transmission mechanisms run.
  3. In encryption, a session is understood to be the exchange of messages, protected by encryption techniques. For example, an SSL session uses a simple key to transmit messages on the network.
  4. For compact discs(CDs), a session is a self-contained recording session that begins with a lead-in and ends with a lead-out. A session may include only one data track, but may include multiple audio tracks.
  5. In SNA, a session is a logical connection through which two NAUs communicate with each other. A parallel session is said to exist when two or more concurrently active sessions exist between two identical Logical Units( LU) in the SNA architecture using different network addresses. Each session can have different transmission parameters.
