(1) The work period of a representative organ, international organization, scientific conference, or other body. In the USSR the session is the basic legally established work period of the soviets of people’s deputies.

Regular sessions of the Supreme Soviet of the USSR are called at least twice a year, and sessions of oblast and krai soviets at least four times a year.

1. A lasting connection between a user (or user agent) and a peer, typically a server, usually involving the exchange of many packets between the user's computer and the server. A session is typically implemented as a layer in a network protocol (e.g. telnet, FTP).

In the case of protocols where there is no concept of a session layer (e.g. UDP) or where sessions at the session layer are generally very short-lived (e.g. HTTP), virtual sessions are implemented by having each exchange between the user and the remote host include some form of cookie which stores state (e.g. a unique session ID, information about the user's preferences or authorisation level, etc.).

See also login.

2. A lasting connection using the session layer of a networking protocol.
