Line 5: Collision avoidance is used to improve the performance of '''CSMA''' by attempting to reserve the network for a single transmitter. This is the function of the "jamming signal", which is implemented as '''Request To Send''' in some versions (for example, see [[802.11 RTS/CTS]]). The performance improvement is achieved by reducing the probability of collision and retry. Extra overhead is added due to the jamming signal wait time, so other techniques give better performance. ~~See~~ [[AppleTalk]] ~~for a classic implementation of~~implemented '''CSMA/CA''' onusing a anthree-byte ~~electrical~~jamming ~~bus~~signal. Compare use of the jamming signal in [[Carrier sense multiple access with collision detection]] ('''CSMA/CD'''), which uses another technique to improve '''CSMA''' performance.
