Process before swapping is residing in the primary memory in its original form. The regions (text, data and stack) may not be occupied fully by the process, there may be few empty slots in any of the regions and while swapping Kernel do not bother about the empty slots while swapping the process out.

After swapping the process resides in the swap (secondary memory) device. The regions swapped out will be present but only the occupied region slots but not the empty slots that were present before assigning.

When hierarchical routing is used, the routers are divided into what we will call regions, with each router knowing all the details about how to route packets to destinations within its own region, but knowing nothing about the internal structure of other regions

The memory in the Virtual Machine is divided into a number of regions. One of these regions is PermGen. It~s an area of memory that is used to (among other things) load class files. The size of this memory region is fixed, i.e. it does not change when the VM is running. You can specify the size of this region with a commandline switch: -XX:MaxPermSize .
The default is 64 Mb on the Sun VMs.
If there~s a problem with garbage collecting classes and if you keep loading new classes, the VM will run out of space in that memory region, even if there~s plenty of memory available on the heap. Setting the -Xmx parameter will not help: this parameter only specifies the size of the total heap and does not affect the size of the PermGen region.
