Linux is a viable alternative to Microsoft Windows. It is open source which means that the installation, media and all of its software are free for anyone to use. There is no license fee or subscription requirement and no built in spyware. Linux is far more secure than other operating systems due to its design and does not require antivirus software.
All software comes from a software centre which is thoroughly checked for viruses. Linux supports major browsers such as Chrome, Firefox and many others.
Linux has free software for word processing, spreadsheets, accounts, video/music creation and playback, photo manipulation and a host of others for your daily needs.
Linux requires less resources than Windows or Mac and, as such, is suitable to run on older computers as well as high powered ones. It does not get slower over time as its files do not fragment and it does not build up temporary files, meaning that it always runs at the same speed as the day you install it. Linux does not need to be restarted every time it updates and never asks you to wait while it does.
Linux can run for several years without a restart and, on the seldom occasion it requires one, it restarts immediately.
Running a Linux operating system means that you choose exactly which software is on your computer; you have total control. It does not come with bloatware and annoying pop ups. You can save money by installing it on an older computer instead of buying a new one.
With Linux you are the User not the Product.
