Why operating systems need updating
The three most common operating systems for personal computers are Microsoft Windows, Mac OS X, and Linux.
Modern operating systems use a graphical user interface, or GUI (pronounced gooey).
An operating system is the most important software that runs on a computer.
It manages the computer's memory and processes, as well as all of its software and hardware.
The operating systems we've been talking about so far were designed to run on desktop and laptop computers.In the screenshot below, you can see i OS running on an i Pad.Operating systems for mobile devices generally aren't as fully featured as those made for desktop and laptop computers, and they aren't able to run all of the same software.Over the years, there have been many different versions of Windows, but the most recent ones are Windows 10 (released in 2015), Windows 8 (2012), Windows 7 (2009), and Windows Vista (2007).Windows comes pre-loaded on most new PCs, which helps to make it the most popular operating system in the world.
