The first computers lacked operating systems. Each programme that ran on these early computers had to include all of the code required to run on the computer, interface with the associated hardware, and execute the computation that the programme was designed to do. Because of this, even the simplest programmes became extremely complex.

In response to this issue, the proprietors of central computers began to design system software that facilitated the authoring and execution of the computer's programmes, giving birth to the first operating systems.

General Motors produced the first operating system in 1956 to run a single IBM central computer.

When computers could only run one programme at a time in the 1950s, the first operating systems were created. Later in the following decades, computers began to integrate an increasing number of software programmes, commonly referred to as libraries, which came together to form the foundation of today's operating systems.

The original version of the Unix operating system was created in the late 1960s. Written in the computer language C, it was initially offered for free. Unix adapted swiftly to new platforms and gained widespread appeal.

Many modern operating systems, notably Apple OS X and various variants of Linux, are based on or date from the Unix OS.

Microsoft Windows was created in response to an IBM request for an operating system to run its personal computer (PC) line.

Microsoft's first operating system, MS-DOS, was released in 1981 after the company purchased the 86-DOS operating system from Seattle Computer Products and tweaked it to suit IBM specifications.

When a graphical user interface was built and coupled or connected with MS-DOS in 1985, the moniker Windows was first used.

As previously said, Apple, OS X, Microsoft Windows, and different kinds of Linux (including Android) now control the great bulk of the current operating system market.

Operating Systems for Video

Here's a video that covers everything about operating systems in a very basic way, including which OS to use. After studying the operating system, we propose performing the following exercise in the form of a Test: Examine the operating systems.

Most software packages are designed to run with a single company's operating system, such as just Windows (Microsoft) or only macOS (Apple). A software will explicitly specify which operating systems it supports and, if necessary, will be quite detailed about which version or versions of that OS it supports.

A video production software package, for example, may state that it is compatible with Windows 10, Windows 8, and Windows 7, but not with earlier versions of Windows such as Windows Vista and XP.

Additionally, software developers generally produce alternative versions of their programme that function with different operating systems or versions. Returning to the video production programme example, the corporation could alternatively release a version of the programme with the same functionality but designed to run with macOS rather than Windows.

It is also critical to understand whether your operating system is 32-bit or 64-bit. It's a regular inquiry when you're downloading software. The steps below will show you how to determine whether your computer is 32bit or 64bit.
