In telecommunication, a jam signal is a signal that carries a bit pattern sent by a data station to inform the other stations that they must not transmit.
Note 1: In carrier sense multiple access with collision detection (CSMA/CD) networks, the jam signal indicates that a collision has occurred.
Note 2: In carrier sense jam camera signal multiple access with collision avoidance (CSMA/CA) networks, the jam signal indicates that the sending station intends to transmit.
Note 3: "Jam signal" should not be confused with "electronic jamming."

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
