Unlike Windows, Linux is free for public to use. So this is an additional advantage to do Linux courses. If you have to buy an original copy of Linux, you need not to pay any money like Fedora or Ubuntu which is available after paying least 100-200 US dollars.
If you get something for free, there cannot be a better thing than that. Since Linux is free of cost, you can go on exploring more opportunities and also try working on more programs. This also gives you an opportunity to enhance your system with the saved money. Contact Comat for more information on Linux operative system and its free availability.
