• An operating system brings powerful benefits to computer software and software development. Without an operating system, every application would need to include its UI, as well as the comprehensive code needed to handle all low-level functionality of the underlying computer, such as disk storage, network interfaces, and so on.
• Operating systems were first developed in the late 1950s to manage tape storage.
• The General Motors Research Lab implemented the first OS in the early 1950s for their IBM 701.
• In the mid-1960s, operating systems started to use disks
• In the late 1960s, the first version of the Unix OS was developed.
• The first OS built by Microsoft was DOS. It was built in 1981 by purchasing the 86-DOS software from a Seattle company
• The present-day popular OS Windows first came to existence in 1985 when a GUI was created and paired with MS-DOS.
• OS Name: Windows, Android, iOS, Mac OS, Linux, Chrome OS, and Windows Phone OS. Hence, Option 3 is correct.
