Ubuntu 14.04.2 download install#

So the operating system needs a mechanism to install packages easily as needed. Including them all in a single operating system package would make the size of the operating system unnecessary large and harder to distribute. Now, there are so many softwares on Linux that you can’t even count. Ubuntu, Debian, CentOS, Fedora and others are Linux distributions or Linux based operating systems. This is called a Linux based operating system or a Linux distribution. So when you install it, you can start working with the program you need. So different companies and individuals packaged important tools (or softwares) on top of Linux kernel and packaged it for you. Again, installing programs on top of Linux kernel is not something ordinary people would love to do. Without useful programs, Linux kernel is of no help to ordinary users. You have to install it on top of the Linux kernel separately in order to use it. Let’s say, you want to edit a file with nano text editor. It’s a software that manages the hardware, allocates memory to programs, helps you run the program, and other basic very low level task for you. Well, Linux kernel itself can’t do very fancy things. Now you may ask, “What is a Linux distribution?” These are actually different Linux distributions. If anyone asks, “what operating system do you use?” Most of you might say, “I use Linux”. We use Ubuntu, Debian, CentOS and different operating systems.
