What is Linux distro?

Linux distro (short for Linux distributions) is a term for computer operating systems and applications, is a family of Unix that uses the Linux kernel. Linux distributions can be free software and can also be a commercial software such as Red Hat Enterprise, SuSE, and others.
There are many distributions of linux that has emerged. Some survive and great, even to produce derivative distributions, eg distributions Debian GNU / Linux. This has resulted in dozens of distros distributions of children, among others Ubuntu, Knoppix, Xandros, DSL, and so on.
To get a linux distro, you can download directly from the distributor distro site concerned, or buy from local sellers.

Linux CD (ie CD or CD distributions of Linux Operating System and Linux applications) is a term often used to refer to the CD distribution of Linux in general.
In computing, tar (derived from tape archive) is a file format (in the form of a type of archive bitstream) and the name of the program used to handle the file. This format was invented in the early days of Unix and standardized by POSIX.1-1988 and later POSIX.1-2001.
Originally developed for sequentially written directly to the I / O tape devices for backup purposes, is now often used to collect many files into one larger file for distribution or archiving, while preserving file system information such as user and group permissions, dates, and directory structure.
A software repository is a storage location of the various software packages that may be retrieved and installed on the computer. Many software publishers and other organizationsmaintain a server on the Internet for this purpose, either for free orfor a subscription fee.
The repository may only be for certain programs, like CPAN forPerl programming language, or for the entire operating system.Operators repositories usually provide a package management system, tools that are intended to find, install and otherwise manipulate software packages from the repository.
For example, many Linux distributions use the AdvancedPackaging Tool that is commonly found in the Debian-baseddistro, or yum commonly found in Red Hat-based distros. There are also some independent package management system, such as Pacman, used in Arch Linux and equo, found on SabayonLinux.
Most Linux distributions have many repositories around the world that mirrors the primary repository.
Linux distributions can be categorized based package management system, free and not, the purpose of manufacture, the basic software used, and so forth.
