Question 1

What is virtual memory?

Accepted Answer

A swap partition enables virtual memory.Virtual memory means you have what seem to be unlimited memory resources.Swap partitions accomplish this by providing swap space on a disk and treating it like an extension of memory (RAM).It is called swap space because the system can use it to swap information between disk and RAM.Setting up swap space makes your computer run faster and more efficiently.

Question 3

When configuring file permissions in UNIX-Linux systems,what is the role of the sticky bit?

Accepted Answer

On older UNIX and Linux distributions,the sticky bit has been used to cause an executable program (a file you run as a program)to stay resident in memory after it is exited.This action ensures that the program is immediately ready to use the next time around or that it stays ready for multiple users on a server.In current operating systems,the sticky bit is used instead to enable a file to be executed,but only the file's owner or root have permission to delete or rename it.The symbol for the sticky bit is t (used in place of x),such as when you view permissions using ls -l.For example,when the sticky bit is set on a file,the permissions might look like: -rwxr-xr-t.
