An operating system is a software program that enables the computer hardware to communicate and operate with the
computer software.For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware.The dominant desktop operating system is Microsoft Windows with a market share of around 82.74%. Mac OS by Apple Inc. is in second place (13.23%), and the varieties of Linux are collectively in third place (1.57%).In the mobile sector (smartphone and tablet
combined) use in 2017 is up to 70% of Google's Android.In the 1940s, the earliest electronic digital systems had no operating systems.In the early 1950s, a computer could execute only one program at a time.Later machines came with libraries of programs, which would be linked to a user's program to assist in operations such as input and output and generating computer code from human-readable symbolic code. This was the genesis of the
modern-day operating system.An improvement was the Atlas Supervisor introduced with the Manchester Atlas commissioned in 1962, "considered by many to be the first recognizable modern operating system".Brinch Hansen described it as "the most significant breakthrough in the history of operating systems.
