There are many operating systems available for desktop computers, Android and iOS are to of the most dominant mobile operating systems and Microsoft Windows and Apple Mac are two of the most commonly adopted desktop computers operating systems worldwide, the only drawback of these two operating systems is that they’re not free ( Mac OS is now free and Windows 10 will be free to upgrade to) but if you’re looking for a free and open source operating system then look no further than Linux. Linux Mint is the best Linux distro for beginners to start tinkering with Linux.
