Linux is a free open source operating system based on Unix, which runs
on varieties of hardware platforms. It is originally developed by Linus
Torvalds at the University of Helsinki in Finland. Linux source code is freely available to everyone under the GNU General Public License.
Significance of Linux
The Linux is used on cell phones, game machines, notebook computers, desktop computers, workstations, mainframes, supercomputers etc.
Most commonly Linux is being used by Government and Defense
departments, Academic institutions, Banking and financial sectors,
Biotechnology engineers, Multi-National Companies, Corporate Sectors,
Vendors and now even Hollywood film Industry.
as a Command Line Interface (CLI) Vs. Graphics User Interface (GUI)
Linux comes in two sort of forms: Command Line Interface and Graphics User
Interface. The text shell provides CLI, which supports only text but perform
high efficiency and speed while graphics shell provide GUI, which support
all sorts of graphics including text and gives tough competition to Windows
operating system duo to it's efficiency and speed.
Linux in Internet
Linux is very useful in Internet due to being cheaper, fast accessing
qualities and a very high quality security reason.
Vs. Windows (A Comparison)
Both Linux and Windows works as an operating system. Both are highly
popular and are in the great demand. The user have their specific reason to
use either Linux or Windows. A comparison gives the exact figure where these
are more suitable or superior.
The Linux distribution is the combination of an installation
program with various open source software and applications in an operating
system package. There are more than three hundreds Linux
distributions are available in the market.
Linux has an interesting advantage over Windows. Some
distributions of Linux like Knoppix, Gnoppix, SuSE (called Live-Eval), Linspire (formerly Lindows) and Slackware
can run directly from CDs without installing them on the hard disk.
Requirement for Linux
For Installing Linux Server/ Desktop Operating System, it need a specific configuration of hardware platform. The hardware also depends upon the sorts of Linux distribution. Here we are telling about
the minimum hardware requirement for installing Fedora Core 6.
Installing Linux is a very challenging job. There are
huge numbers of Linux distribution available in the market. Each
distribution has a specific criteria for installing. The installing process
also differs for different sorts of computer processor and
Linux and Windows (Dual Installation)
Installing Linux on a fresh computer differs from installing it on the
pre-existing operating system. This is called dual installation. Installing Linux
on the pre-installed system needs an additional hard disk partition.
Started in Linux (Booting.)
Booting is a built-in program that loads operating system into the memory. We
are giving the various steps of booting system by Linux for x86 system.
Problem and Troubleshooting while
As installing Linux is a tough job for the new user, he/she has to face lots of
problems for installing Linux. The common problems and their solutions are given
in this section. The act of solving the problem is called troubleshooting.
to Shut down Linux
Shutting Down Linux has a specific criteria like
windows have. We should follow the instructions, otherwise hard disk may be format
or data may be loss.
The Shell in Linux.
A shell is an advanced way for communicating to the system. The term 'shell' originates by its general term name 'shell' of the kernel. It means being an outer layer of interface between the user and the kernel (the innards of the operating system).
It allows the user to handle a system in a flexible way for conversation and taking initiative. It
also allows the user for task automation.
The Bash shell is the main port for entering into Linux. The shell interprets
everything you enter on the command line before passing it along to the
operating system for execution. Bash has its own powerful built-in programming
Linux is very relevant in terms of security. It is highly recommended to
use Linux for asking a very secure platform. Linux security system works as a
fort for different sorts of virus, worms, Trojans and data loss. It also
prevents the data hacking.
Though Linux has lots of advantages and significance, it has some
