UNIX/Linux versus Mac versus Windows
Really, I’m not out to destroy Microsoft. That will just be a completely unintentional side effect.
-Linus Torvalds
I wish him the best, I really do. I just think he and Microsoft are a bit narrow. He’d be a broader guy if he had dropped acid once or gone off to an ashram when he was younger.
- Steve Jobs
Microsoft has had clear competitors in the past. It’s a good thing we have museums to document that.
- Bill Gates (Torvalds, Gates, & Jobs, 2013)
Operating systems were not in existence before the 1960s. The definition of operating systems is a program designed to run other programs on the computer and is the most important program. In the past, computers were built to execute a series of single task similar to a calculator. In the 1960s came the MCP (Master Control Program) for the B5000 mainframe computer created by the company Burroughs/Unisys. The MCP was the first OS written exclusively in a high-level language. As the years progressed, OS giants were starting to form such as Windows, Linux, and Mac. In, this paper, these 3 tech OS giants will be examined thoroughly while covering memory management, process management, file management, and security.
The UNIX and Linux Operating Systems (OS) are open source systems. The first version of UNIX was created in 1969 by computer scientist Kenneth Thompson at AT&T Bell Laboratories. The system was based on four parts: the shell, kernel, editor, and the assembler. Linux was created as a free software substitute to the commercial UNIX environments. The history of Linux dates back to 1983 and Linux runs a much greater range of platforms than most UNIX environments. Both OS share a common foundation because of the history and tradition.
Memory management is an important part of an operating. The UNIX/Linux OS use numerous intricate algorithms for memory management which will permit the system to
