I am very much confused with these questions.
On a 32 bit processor, every process has 4 GB virtual memory. But, if evey process has 4gb space than it will be every huge amount if 100 process is running - this is greater than swap area. Can someone please explain this; I am very confused.
How does the operating system allocate the memory to a process? Suppose a process has
a = malloc(2). Who will allocate this memory to the process? Will the OS give these 2 Bytes memory to the process.
(We access the a[2] it generate the segmentation error).Where do the different parts of the process remains ( Code , Data , Stack, Heap ) in Main Memory or in secondary memory.
Please give me some good link so that I can also understand the virtual memory and its whole mechanism as the links I've found are not fully explaining the virtual memory.
