Multitasking Vs Multithreading Vs Multiprocessing

Well, I'm sure everyone here would agree that you didn't need to ask this on this forum and could have found the information yourself by easily searching Google.

Multitasking is the ability of any operating system to handle the execution of multiple tasks at a time. Microsoft DOS doesn't have this ability and therefore is a single-tasking OS while, Windows 95 on up and Unix/Linux are multi-tasking.

Now in relation to processes: The ability of your processor to handle multiple processes at a time is called multiprogramming (think of processes as the programs you see running when you do a ctrl+alt+del in Windows or a "ps" in *nix), and each individual task in a process is called a thread. Each thread's task is independent of the other. So when multiple threads execute simultaneously it is called Multithreading. So the last one would be multiprocessing, which is when multiple processors execute multiple processes or threads on the processors simultaneously.

They all speak for themselves really and it isn't really hard when you think about it. Now it isn't really true when they say two or more things are executing at the same time. The execution of these tasks are happening so fast that us humans don't even realize it and it seems as though they are executing simultaneously when in acutality they are really executed one after the other.

Oh, and the actual name for both multiprogramming and multithreading is multitasking.

I hope this clears things up for you.
