I quoted 3 explanation about a deadlock from 3 websites. The idea of the deadlock in golang and the explanations are the same or similar or different?
A deadlock is a situation in which two computer programs sharing the same resource are effectively preventing each other from accessing the resource, resulting in both programs ceasing to function. https://whatis.techtarget.com/definition/deadlock In general computing, a deadlock is a situation where two different programs or processes depend on one another for completion, either because both are using the same resources or because of erroneous cues or other problems.https://www.techopedia.com/definition/2766/deadlock-computers There was a time where operating systems were only able to execute a single process at a time, thus giving full system resource and attention to that one single process. Nowadays operating systems can handle multiple tasks at once, but sometimes they have to deal with a problem known as a deadlock. A deadlock occurs when there is at least one process, who is waiting for resources to be released by another process, in order to finish a task correctly. https://study.com/academy/lesson/what-is-deadlock-definition-examples-avoidance.html 2019年1月29日火曜日 17時55分17秒 UTC+9 伊藤和也: > > I know the general meaning of a deadlock, but I don't know the meaning of > a deadlock in golang.
