Threads called the "unit of dispatch" but what does that mean? I was looking over the web and two operating systems books but I can't find the answer. It seems that processes are defined by two characteristics: resource ownership and scheduling/execution. I understand that threads are within processes, and that there must be at least one thread. Can someone explain this to me please?
Threads are called the unit of dispatch because they are part of the process in almost all cases.Also they have states and priorities on the basis of which we can apply specific scheduling algorithm for process scheduling.
"Unit of dispatch" just means "the thing that gets scheduled."
