Background. The earliest computers were mainframes that lacked any form of operating system. Each user had sole use of the machine for a scheduled period of time and would arrive at the computer with program and data, often on punched paper cards and magnetic or paper tape.
1. The First Generation (1940 to early 1950s) In 1940, an operating system was not included in the creation of the first electrical computer. Early computer users had complete control over the device and wrote programs in pure machine language for every task.
This guide will journey through the key milestones that allowed operating systems to transform from strictly business-oriented tools in the 1950s into the slick, touch-ready platforms powering our smartphones. Learning this history helps illustrate how small changes over time can culminate in revolutionary capabilities.
The History of Operating Systems. Early computers were impressive, but limited in how many programs they could execute. They had no traditional operating system and relied on punch cards or punched tape. That served as a form of input for early systems of the 1950s.
An operating system is difficult to define, [7] but has been called "the layer of software that manages a computer's resources for its users and their applications". [8] Operating systems include the software that is always running, called a kernel—but can include other software as well.
Develop a framework to think about system functionality and how and why it evolved. Explain how external forces (e.g., technology and human capital) shape operating system design and functionality. Speculate realistically about what changes might lie on the horizon for operating systems.
operating system (OS), program that manages a computer’s resources, especially the allocation of those resources among other programs. Typical resources include the central processing unit (CPU), computer memory , file storage, input/output (I/O) devices , and network connections.

Operating systems have been evolving through the years. In this excerpt from his book, Modern Operating Systems, Andrew Tanenbaum briefly looks at a few of the highlights.
This article presents a timeline of events in the history of computer operating systems from 1951 to the current day. For a narrative explaining the overall developments, see the History of operating systems.
