An operating system is a collection of software that manages computer hardware resources and provides the service for computer programs. For example , when you turn your computer on it will normally flash up with a symbol or brand name ( windows etc.) that will represent what operating system your computer is using. The operating system manages the overall look and feel of the software on the device and how it will be displayed. It also has it's own defaults such as the search browser (Internet Explorer, MSN)
For example if you compared an operating system to a book , the pages on the inside would represent the software on the device and the cover would represent the operating system because it displays the look and feel of the book. The earliest computers didn't have operating systems and would crash regularly and all computers were the same. The first operating system to be made was the " Lyons electronic office" which was supported by the British business firm J.Lyons and co.
