Welcome to Linux world. There is a Linux OS for everyone. Most of the Linux OS does not require a heavyweight computer system. But even if your system is one of those of late 90’s or early 2000’s, there are plenty of leightweight distributions.


Linux was one of the first open-source technologies, but many programmers have contributed and added software that’s completely open-source for any user. This means that you can download the source code and change it any way you like. Some developers have restrictions on how you can distribute the code. For instance, some developers allow you to change the code, but you cannot distribute it for money.

One main advantage of open source technologies such as Linux is the wide range of options available to users and the increased security. With Linux being open-source, several distributions are available to the end-user. Debian, Fedora, Ubuntu and Mint are just a few of the distributions available to end users, and these distributions are completely free to download.

Security is the other main advantage. Several white hat hackers have contributed to the overall security of Linux, and by making the source available to anyone, security experts can help identify any main security flaws in the operating system. The advantage over operating systems such as Windows is that security flaws are caught before they become an issue for the public.
