  History of operating systems - Wikipedia, the free encyclopedia
An operating system, or "monitor" as it was sometimes called, permitted jobs to become multistep with the monitor running several programs in sequence to effect the translation and subsequent run of the user's program.
Early systems had utilized Microprogramming to implement features on their systems in order to permit different underlying architecture to appear to be the same as others in a series.
The system is an example of a system which started as a database application support program, graduated to system work, and still exists across a wide variety of systems supported on most UNIX systems as an addon database system.

 Operating system - Wikipedia, the free encyclopedia
As well as the kernel, an operating system is often distributed with system software that manages a graphical user interface (although Windows and Macintosh have integrated these programs into the operating system), as well as utility programs for tasks such as managing files and configuring the operating system.
Commercially-supplied operating systems are present on virtually all modern devices described as computers, from personal computers to mainframes, as well as mobile computers such as PDAs and mobile phones.
Mainframe operating systems, such as IBM's z/OS, and embedded operating systems such as VxWorks, eCos, and Palm OS, are usually unrelated to Unix and Windows, except for Windows CE, Windows NT Embedded 4.0 and Windows XP Embedded which are descendants of Windows, and several *BSDs, and Linux distributions tailored for embedded systems.

 History of Operating Systems
Historically operating systems have been tightly related to the computer architecture, it is good idea to study the history of operating systems from the architecture of the computers on which they run.
Operating systems have evolved through a number of distinct phases or generations which corresponds roughly to the decades.
So operating systems designers developed the concept of multiprogramming in which several jobs are in main memory at once; a processor is switched from job to job as needed to keep several jobs advancing while keeping the peripheral devices in use.

 Nature and History of Operating Systems for Computers
An operating system is a program that runs on a computer to simplify the use of the computer for the user.
In order to carry out these functions the operating system has to require a systematic structure for the inputs and outputs; there is a definite structure to files and there is a systematic way in which the files are stored on the data storage devices.
Although now the concept of an operating system appears to be a natural and obvious one, operating systems evolved over a considerable period of time.

 Iterations: An interdisciplinary journal of software history
The system software itself had to be supremely reliable, and coordinate the sharing of memory, disk, and processor resources between hundreds of users while protecting itself from tampering or corruption.
Multicians complain that later and more commercially successful systems included implementations of features such as memory segmentation, dynamic linking, and security that were not merely guilty of failing to improve on their own work, but were actually designed in ignorance of their labors.
The second goal, to "record the history of the system, its builders, and its users," is the hardest to achieve—because of its breadth, and because it implies the eventual transmission of this information beyond the Multicians themselves.

Examples of operating systems that were primarily batch-oriented include: BKY, BOS/360, BPS/360, CAL, and Chios.
The first operating system to introduce system calls was University of Machester’s Atlas I Supervisor.
A few newly hired engineers were unable to get valuable mainframe computer time because of lack of seniority and resorted to writing their own operating system (UNIX) and programming language (C) to run on an unused mainframe computer still in the original box (the manufacturer had gone out of business before shipping an operating system).

 CS322: Operating Systems History
Spooling batch systems were the first and are the simplest of the multiprogramming systems.
One advantage of spooling batch systems was that the output from jobs was available as soon as the job completed, rather than only after all jobs in the current cycle were finished.
The operating system is responsible for switching between the jobs, now often called processes, in such a way that favored user interaction.

Just as this document provides a super-detailed history of Apple's operating systems, the book itself is super-detailed on the internals of modern day Mac OS X. It is not at all a book about using Mac OS X—it is about the system's design and implementation.
Therefore, I expect it to appeal to all operating system enthusiasts and students.

 Operating Systems Through Time (8-bits)
While some operating systems, like the love-hate Unix, have been around since the early days of digital computing (read 1960's), most have appeared in the late 70's to the present time, varying from powerful multiuser OS's to little OS's that ran on 8 bit computers in under 64K of memory.
Its operating system was BASIC, but had a built-in ML monitor and could generate a fl-and-white TV display with its 4K of RAM (max 8K).
OS9 was an operating system that was one of the few, if not the only, multitasking, multithreading, and, if you're lucky, multi-user operating systems extant for an 8-bit system.
