Anoperating system (or OS) is the name for a group of computer programs, device drivers, kernel, and other things that let a user work with a computer. It can be small (like MenuetOS), or big (like Microsoft Windows). Different operating systems can be used for different purposes. Some are used for every day things like on a personal computer. Others are used for specialized work.
An operating system has many jobs. It is responsible for making sure that all the programs can use the CPU, system memory, displays, input devices, and other hardware. It also lets the user have a fast, clean, and safe interface so they can do work on the computer. It also talks to other computers or devices on a network. There are many operating systems such as macOS, Linux, and Microsoft Windows.
History[change | change source]
The first operating system was used with the ENIAC (Electronic Numerical Integrator and Computer). It was very hard to make ENIAC do work. How the operating system worked was based on how the switches and cables were put together and depending on this factor punch cards would make a result. While this was an operating system of a kind, it is not what is thought of as one in modern times.
The first operating system that looked and felt like operating systems in the modern age was UNIX, made in 1969 by Bell Labs. It had a small kernel and many tiny programs that could be put together to work with user input and data. Many of its features were taken from Multics, an older operating system made in 1964.

The Evolution Of Microsoft Operating Systems
The Microsoft operating system has seen many changes over the last twenty years. From Microsoft?s Disk Operating System (DOS) introduced in 1981 to Windows Millennium Edition, first seen on store shelves in late 2000, Microsoft?s operating system has changed completely. What began as a difficult to understand, and sometimes difficult to use, text only operating system, has evolved into a completely graphical, very user-friendly interface. As computer hardware changes, so must the software connecting it with the user. Microsoft?s operating systems have evolved and changed greatly with the evolution of computer systems.
Microsoft?s DOS 1.0 became one of the most important operating systems for personal computers when IBM chose to use DOS in many of their PCs. The only competitor for the operating system at the time for Intel?s 8088 processor was a version of CP/M (Control Program/Monitor) published by Digital Research and sold for $249. It also did not come bundled with any programming software, meaning you would have to buy UCSD (University of California at San Diego) p-system, which was based on the Pascal programming language, and sold for another $149. At the time, Microsoft had recently purchased QDOS (Quick & Dirty Operating System) from Tim Paterson of Seattle Computing. Microsoft then offered to license a customized version of QDOS bundled with BASIC (Beginner's All-Purpose Symbolic Instruction Code) to IBM. IBM accepted the offer, and later marketed the operating system as PC-DOS. Since Microsoft only licensed DOS to IBM, they retained the rights to sell it to users and other companies as they wished. PC-DOS and MS-DOS both cost $49, a considerable savings over the CP/M and UCSD p-system combination, and in most cases IBM gave PC-DOS away with their computers. Soon, 99% of all PCs were running Microsoft?s DOS.
MS-DOS was a 16-bit, single user, single tasking, text-based operating system. Now considered obsolete because of its inability to make use of many of the newer components to a PC as well as its lack of support for the latest and fastest designs, many developers still choose MS-DOS operating system or one similar to it because the user has more control over all of the system resources. It is also used at times when users are in need of a very simple yet effective means of communicating with the hardware within their computers. As DOS was made bigger and better, later versions of MS-DOS included improvements on previous versions, new software like Excel, Word, Microsoft Works and Office, and made its way through at least fifteen different versions.
Microsoft began work on Interface Manager in September of 1981, which later became known as Windows. The first prototypes used Multiplan (an early Microsoft spreadsheet program...
