#Ai dispatcher run 8 v2 software

It may make a more clear view for you.Ī dispatcher is a special program which comes into play after the scheduler. Let’s have a look at the figure given below. This decision is handled by short term scheduler. Among all of the process, a single process is to be selected for execution. Short term (CPU) scheduler – When there are lots of processes in main memory initially all are present in the ready queue.Medium-term scheduling is a part of swapping. ALL these decisions are taken by the medium-term scheduler. When a process completes its I/O operation then it should again be shifted to ready queue. Hence during the execution of a process when a I/O operation is required then the operating system sends that process from running queue to blocked queue. Medium term scheduler – Most often, a running process needs I/O operation which doesn’t requires CPU.Hence, in simple words, long term scheduler decides the degree of multi-programming of system. This is the decision of long term scheduler that how many processes will stay in the ready queue.

When they are stored or loaded in the main memory they are called process.

Long term (job) scheduler – Due to the smaller size of main memory initially all program are stored in secondary memory.

Their main task is to select the jobs to be submitted into the system and to decide which process to run.
