hi friends,
when we open run any application like Web Browser, MS Word, Winamp etc, then why a processes associated with that always starts as we can see this on task manager->processes.


what is the relation between an application and it's associated process?
An application is what's being run by the user and a process is the executing program for that application. The examples you give are fairly simple ones but the application and process names can be different. The Application is just a name, usually selected by the PROGRAMMER, to identify what is running.

Have a look at the top of the screen, you will find an application name (btw I'm using Firefox for this example), it should say "SYSTEM processes and system applications - MOZILLA Firefox". Now hit Alt+Ctrl+Del to open WINDOWS Task Manager and you should find the same thing in Applications. Right CLICK on it then click "Go to Process" and you should be taken to Firefox.exe in Processes.

So the Application is "system processes and ....etc" while the program being used in that application is Firefox.exe

Some applications seem to have no link whatsoever to the running process. One example is a small program named ipcountrylookup.exe while the application name is Project1.

Hope the above helps.
