What part of the operating system also known as virtual memory is contained in its own partition in linux?

Your question does not make sense.

But anyway, virtual memory is basically using harddrive space as fake memory larger than ram. Linux have option to place it on separate partition for efficiency. If you let it use a file, double management of file and virtual memory must be managed.

How can you override all other system users without administrator permission?

You can't. The only way to bypass access privileges without having administrative privileges is via bugs in a program already running with administrative permissions. Since most programs aren't (or shouldn't be) run with administrative privileges, you can't rely on 1.) a program to be running with high privileges, and 2.) for it to have unpatched bugs. If such a bug was known, it would become patched fairly quickly (at least in the case of Linux).

No. Its support status in Arch Linux is currently unofficial with the official Arch kernel.

How do you prevent deadlock in Linux?

Deadlock is not really anything a user has to worry about. Deadlock is merely what happens when two objects want to make the use of each other's resource, but won't release the resource they have until they get the resource they want.

How this is usually prevented is to have an object drop ANY resource it no longer needs before trying to get a new resource. This is just one approach, as it doesn't stop deadlock if both objects need the resource they have but need a resource the other object needs.

What does the 'which' command do in Linux?

What are the major steps necessary for implementing routing on a Linux network?

Answer:

NOTE: It is suspected that this question has been reproduced from an exam, quiz or test of some sort.

Step 1

The question is vague, but if you intend to use a Linux machine as a router you'll need multiple physical interfaces connected with your cat 5 or other cabling as well as all switches etc. set up and operating.

Step 2

Configure your connected ethernet interfaces (typically with ifconfig).

Step 3

Configure your routing table (typically with the route command or it's equivalent).

Step 4

Make any necessary changes to your routing host firewall (typically iptables or other).

Step 5

Enjoy the fruit of your labors.

NOTE: Much has intentionally be omitted from this answer because the question is too vague to justify a detailed response.

Which one of the following utilities do you use on a Linux system to display the contents of a text file?

While you could use any text editor you like, the most direct way would be:

$ cat filename

Of course, if the text is large and spammy, you might wanna make it something you can handle a little better:

$ cat filename | less

I prefer less to more as more only lets you scroll down, whereas less lets you go both ways.
