WebEvery computer system has a limit to the degree of multiprogramming it will support. This limit is primarily based on the amount of main memory available to the system and the efficiency of the operating systems resource allocation algorithms.

If the degree of multiprogramming is stable, then the average rate of process creation must be equal to the average departure rate of processes leaving the system. Option(B) : Multiple process of a single program cannot exist – False. Web12 dec. 2024 · Multithreading is an execution model that allows a single process to have multiple code segments (i.e., threads) run concurrently within the “context” of that process. You can think of threads as child processes that share the parent process resources but execute independently. garlic budder humboldt seed company

WebIf the level of multiprogramming is reduced resident processes would page fault less frequently and the CPU utilization would improve. Another way to improve performance would be to get more physical memory or a faster paging drum. a. Get a faster CPU—No. b. Get a bigger paging drum—No. c. Increase the degree of multiprogramming—No. d. Webdegree of multiprogramming (no. of processes in memory at a time). If the degree of multiprogramming is to be kept stable (say 10 processes at a time), then the long-term scheduler may only need to be invoked when a process finishes execution.
