The operating system provides an interface between an application program and the computer hardware, so that an application program can interact with the hardware only by obeying rules and procedures programmed into the operating system. The operating system is also a set of services which simplify development and execution of application programs.
Banker's algorithm is a resource allocation and deadlock avoidance algorithm developed by Edsger Dijkstra that tests for safety by simulating the allocation of predetermined maximum possible amounts of all resources, and then makes an "s-state" check to test for possible deadlock conditions for all other pending activities, before deciding whether allocation should be allowed to continue.
templating: In an o/s context, templating refers to creating a single virtual machine image as a guest operating system, then saving it as a tool for multiple running virtual machines (Gagne, 2012, p. 716). The technique is used both in virtualization and cloud computing management, and is common in large server warehouses.
This category and its subcategories deal with operating systems, the system software responsible for the direct control and management of hardware and basic system operations, as well as running application software such as word processing programs and Web browsers.
The Multics operating system is probably the best known system implementing segmented memory. Multics segments are subdivisions of the computer's physical memory of up to 256 pages, each page being 1K 36-bit words in size, resulting in a maximum segment size of 1MiB (with 9-bit bytes, as used in Multics).
Operating Systems: Design and Implementation is a computer science textbook written by Andrew S. Tanenbaum, with help from Albert S. Woodhull. The book describes the principles of operating systems and demonstrates their application in the source code of Tanenbaum's MINIX , a free Unix-like operating system designed for teaching purposes.

Microsoft Windows CE was the base for Pocket PC 2000, renamed Windows Mobile in 2003, which at its peak in 2007 was the most common operating system for smartphones in the U.S. In 2007, Apple introduced the iPhone and its operating system, known as simply iPhone OS (until the release of iOS 4), which, like Mac OS X, is based on the Unix-like ...
It is now in its 5th edition, published October 2022 (ISBN 9780137618880), written together with Herbert Bos. Modern Operating Systems (mostly known as MOS) is a popular book across the globe and includes the fundamentals of an operating system with small amounts of code written in autonomous C language. MOS describes many scheduling algorithms
