Editing Bus contention (section)

{{Short description|Condition where multiple devices on a computer bus attempt to use it at the same time}}
{{distinguish|resource contention}}

'''Bus contention''' is an undesirable state in [[computer design]] where more than one device on a [[bus (computing)|bus]] attempts to place values on it at the same time.  

Bus contention is the kind of [[Contention (telecommunications)|telecommunication contention ]] that occurs when all communicating devices communicate directly with each other through a single shared channel, and contrasted with "network contention" that occurs when communicating devices communicate indirectly with each other, through point-to-point connections through routers or bridges.<ref>

Bus contention can lead to erroneous operation, excess power consumption, and, in unusual cases, permanent damage to the hardware—such as burning out a [[MOSFET]].<ref name="dunton">
