Linux

Linux has a number of schedulers available in its kernel, plus at least one scheduler available as a patch. But the default schedler is the Completely Fair Scheduler. Like most modern schedulers, it is pre-emptive, meaning that instead of the process deciding when to give up the CPU, the kernel decides for it when to give up the CPU. This keeps even the most uncooperative process from starving the other processes on the computer of CPU time. From what I understand of how CFS works: It keeps an eye on how much of an assigned quantum (length of time.) is actually spent on the CPU by a process and how much of the quantum is spent blocking (Keeping off the CPU to wait for I/O requests to complete, a process can't usually proceed and keep going without requested data. During the time a process is waiting for the hardware, other processes make use of the CPU.) The less time a process actually uses the CPU on its given quantum, the higher a priority it gets so that when the data from an I/O operation is complete the process can quickly execute to the next I/O request and block again. This keeps the CPU busy, but the system responsive to just about any event.

I don't know what sort of process scheduling is used on Windows. Windows, unlike Linux, is given a pretty heavy black box treatment when it comes to its users and a great deal about its kernel is not common knowledge. Presumably it is a pre-emptive, priority-based scheduler. Doubtful it's as efficient as CFS.

There's no single file that contains the boot information. Nor is the method of booting uniform across all platforms and distributions. There are dozens of bootloaders, each of which have their own configuration files in various locations.

'dir <directory>' Read the 'dir' manual with the command 'man dir'.

NOTE: The 'ls' command is more commonly used instead of 'dir'.

Below are some examples.

$ dir

Desktop Documents Music Pictures

$ dir Documents

test.txt test.odt test.pdf

$ dir /

bin etc lib lost+found opt run srv usr

boot home lib32 media proc sbin sys var

dev initrd.img lib64 mnt root selinux tmp vmlinuz

Super block is supposed to be the first sector of any file system that can be mounted on Linux operating system.

It is supposed to contain information about the entire file system in that partition.

It has magic number to specify which file system is used in that partition and other parameters to help read/write to that file system.

One can find a Linux game server hosting from most web hosting companies. The best thing to do is to look around the different web hosting companies and choose one which offers what your looking for at the best price.

The following installation methods are available:

CD-ROM

Hard Drive

Network Install (via NFS, FTP, or HTTP)

Kickstart

PXE

Red Hat Network Provisioning

By default,there is only one account, root. However, most Linux distribution will either allow or make you set up a second administrative user account.

Linux usually uses a pre-emptive scheduler, which means a process will run until either it makes a system call, or its time slice runs out. This is as opposed to a cooperative scheduler, which allows a process to run until it deems itself ready to go from running to ready state.

Needless to say, preemption is a much better model, keeping misbehaving processes from starving other processes of CPU time.

The shell prompt is the visual aspect of the shell between running programs, th epart that shows it is waiting for you to give it a command.

The type and amount of technical support is dependent on the provider. The operating system the provider is using has little to no bearing on how much technical support they provide or what features are enabled.

There are too many to list, as the it would take many pages to just list the titles

the most common distributions are:

Centos

Redhat Enterprise

Debian

Ubuntu

Slackware

Gentoo

Yes, and is known as a dual-booting computer. Install Windows first, then your chosen distribution of Linux (Ubuntu is one example). You will be given the choice of which to use at the start of booting up the computer.

Download or buy installation CD.

Lots of time they have thing call LIVE CD where you can boot from CD without installing to HD to test it out.

It can be installed on pen drive or external harddrive too.

It is not recommended but it can be installed on top of windows drive.

Installation will take longer, but if you want thing fastest you will want to install on few separate partitions.

Typically a root user sees the '#' symbol as their prompt. If they already have a prompt via the PS1 shell variable then the # symbol is usually added at the end to indicate that they are a root user in this current context.

ext4 supports a feature called 'journalling' which prevents filesystem corruption in the event of a power failure or system crash. When you are certain you don't need it, you can choose ext2. But for the vast majority of users, ext4 is the best option.

It is the 6th partition of you primary IDE hard drive.

hd stands for hard disk ( Please note that in case of SCSI the names would be sd)

Disks are numbered as hda, hdb, hdc and so on

partitions are numbered as 1, 2, 3 and so on

So hda1 is the first partition on first hard disk and hdb2 is the second partition on second hard disk.

Assuming you are looking for a specific file in a location, it's as simple as ls <name of file.> assuming you are in the directory you expect it to be in.

"Distros", or distributions.

There's Ubuntu, Debian, Red Had, Fedora, Gentoo, Arch, Mint, SuSE, Slackware...

A good way to find out is to look into Distro Watch. The web site more or less keeps a monitor on how popular a given Linux distribution is.

mv file /path/to/directory

You cannot have RAM connected to a PC via a USB Cable. RAM is something that is connected to the PC in the inside of the computer through ports etc. There are several RAM types. If you're looking to improve performance on your PC and have Vista as well as having a flash drive, you can use a special feature which allows the PC to create more virtual memory, which results in faster speed.

The kernel is the core of the operating system.It is loaded into memory when the system is booted and communicates directly with the hardware.Users programs that need to access the hardware,use the services of kernel,which performs the job on user's behalf.
