MS-DOS Operating System
IBM was looking for an operating system for their new line of personal computers. Bill Gates’s mother Marry M Gates served on the national board of United Way alongside the CEO of IBM. IBM got in touch with Bill Gates through his mother when he convinced IBM that his company Microsoft could deliver the new software for IBM’s personal computer. Bill Gates then bought an existing OS called 86-DOS also known as QDOS for Quick and Dirty Operating System. He then adapted QDOS to run on the new IBM computers and called the particular product as “Microsoft Disk Operating System”.
