A panel show or panel game is a radio or television game show in which a panel of celebrities participates. Celebrity panelists may compete with each other, such as on The News Quiz; facilitate play by non-celebrity contestants, such as on Match Game and Blankety Blank; or do both, such as on Wait Wait Don't Tell Me.

One of the two techniques for communicating between parallel processes (the other being shared memory). A common use of message passing is for communication in a parallel computer. A process running on one processor may send a message to a process running on the same processor or another. The actual transmission of the message is usually handled by the run-time support of the language in which the processes are written, or by the operating system. Message passing scales better than shared memory, which is generally used in computers with relatively few processors. This is because the total communications bandwidth usually increases with the number of processors. A message passing system provides primitives for sending and receiving messages. These primitives may by either synchronous or asynchronous or both. A synchronous send will not complete (will not allow the sender to proceed) until the receiving process has received the message. This allows the sender to know whether the message was received successfully or not (like when you speak to someone on the telephone). An asynchronous send simply queues the message for transmission without waiting for it to be received (like posting a letter). A synchronous receive primitive will wait until there is a message to read whereas an asynchronous receive will return immediately, either with a message or to say that no message has arrived. Messages may be sent to a named process or to a named mailbox which may be readable by one or many processes. Transmission involves determining the location of the recipient and then choosing a route to reach that location. The message may be transmitted in one go or may be split into packets which are transmitted independently (e.g. using wormhole routing) and reassembled at the receiver. The message passing system must ensure that sufficient memory is available to buffer the message at its destination and at intermediate nodes. Messages may be typed or untyped at the programming language level. They may have a priority, allowing the receiver to read the highest priority messages first. Some message passing computers are the {MIT J-Machine (http://ai.mit.edu/projects/cva/cva_j_machine.html)}, the {Illinois Concert Project (http://www-csag.cs.uiuc.edu/projects/concert.html)} and transputer-based systems. Object-oriented programming uses message passing between objects as a metaphor for procedure call. (1994-11-11)

Panel (data) analysis is a statistical method, widely used in social science, epidemiology, and econometrics to analyze two-dimensional (typically cross sectional and longitudinal) panel data. The data are usually collected over time and over the same individuals and then a regression is run over these two dimensions.

A Popham panel, or T-signalling panel, was a means of ground-to-air communication, in Morse code, developed during the First World War, before the introduction of radio communication. They were named for Robert Brooke-Popham and were used by the British and American armed forces.

The Twelve Panel is a jewelled enameled Easter egg made under the supervision of the Russian jeweller Peter Carl Fabergé in 1899. The Fabergé egg was made for Alexander Kelch, who presented it to his wife, Barbara (Varvara) Kelch-Bazanova.

The Panel of Chairs (formerly the Chairmen's Panel) are members of the House of Commons of the United Kingdom responsible for chairing public bill committees and other General Committees, as well as debates in Westminster Hall, the parallel debating chamber. The three Deputy Speakers, who are automatically members, are responsible for chairing Committees of the Whole House.

A flat-panel display (FPD) is an electronic display used to display visual content such as text or images. It is present in consumer, medical, transportation, and industrial equipment.

In computing, a private message, personal message, or direct message (abbreviated as PM or DM) refers to a private communication sent or received by a user of a private communication channel on any given platform. Unlike public posts, PMs are only viewable by the participants.

In cryptography, a message authentication code (MAC), sometimes known as a tag, is a short piece of information used for authenticating a message. In other words, to confirm that the message came from the stated sender (its authenticity) and has not been changed.
