An Overview of the Linux Operating
System

Linux is an open-source operating system.

It is Unix-Like that can run on PCs. Unix cannot because of its
complexity.

A Linux distribution is a collection of software (package) built
around the Linux Kernel.

Different distribution are available such as Ubuntu, openSUSE,
Debian, Sugar (Linux for kids), and many others.

Explore Linux distribution on:


Linux provides both graphical and command-line interfaces.

It is recommended that you create an account on the Linux
forum such as:

Operating System Virtualization

Virtualization can be defined as “installing multiple operating
systems on the top of an existing one.”

For example, you can install Linux on top of Windows. In such case,
you can work under both operating systems.

More than one operating system can be installed on top of Windows.

In order to install Linux on top of Windows, we need the following
software:
A) Windows
B) Linux
C) A software that enables us to install Linux on top of Windows

What is a Virtual Machine?

A Virtual Machine (VM) is a software program or operating
system that capable of performing tasks such as running
applications and programs like a separate computer.

Virtual machines allow you to run any operating system in a
window on your desktop.

A virtual machine, usually known as a guest is created within
another computing environment referred as a host.

Multiple virtual machines can exist within a single host at one
time.

How to create a VM

In order to create the VM, you need to:
1.
Install the free VirtualBox or VMware Player.
2.
Download an ISO file for a Linux distribution such as
Ubuntu.
3.
Install that Linux distribution inside the virtual
machine like you would install it on a standard
computer.

Step 3: Running Linux

The default username is oscreader and the password is osc as
well

There is a root user and the password is osc

Running Applications

If you click on the Activities button, a side bar will appear with a
list of useful applications
12
Running Applications (Cont.)

There are no graphical development tools built-in. Rather, you
will have to use a command line where you will find gcc, our C
compiler.
Applications -> Terminal

There is also an editor – gedit. However this is a text editor only. You
can use it to edit your C files, yet you will have to compile it using
the command line.
Applications -> gedit Text Editor
