Linux is a free Operating System and a fit replacement for systems like Windows. With Linux, if something isn’t to your liking, you’re free to change it. You can simplify the Graphic user interface or start menu to your liking.
Unlike Windows, and OSX, Linux is not created and supported by just one company. It is supported by Intel, Redhat, Linaro, Samsung, IBM, SUSE, Texas Instruments, Google, Canonical, Oracle, AMD, and Over 4,000 developers that contributed to improving it over the last 15 years.
The latest improvements from these developers, from trendy to critical, are delivered via security updates, driver updates, application updates, software upgrades, and operating system upgrades.
Despite the occasional vulnerability coming to light, Linux is regarded as much more secure than Windows. As a Unix-like operating system, the platform was designed from the ground up with different privilege levels that make it much harder for malware to get unrestricted access to a system, even if it manages to slip past the defences.
