Deadlock refers to two or more than two processes in the implementation process, because of competitive resources or due to each other communication caused by a blocking phenomenon, without external forces, they will not be able to push down. It is said that the system is in a deadlock state or the system produces a deadlock, and these processes that are always waiting for each other are called deadlock processes.
