About Operating System
Operating System
Operating system and software project that is a full-time open-source research project started in 2012.
The target of this project is to study and develop a full-featured operating system that can run on all alternative computing platforms, including mobile devices, such as Android and iOS devices, servers, supercomputers, and embedded systems.
An operating system (OS) is system software that manages
computer hardware, software resources, and provides common services for
computer programs and users.
Operating systems manage devices, memory, storage devices, peripherals, and services.
Operating systems provide for remote execution of applications access to an operating system's architecture for dynamically managing applications, and implement a user interface with a graphical user interface (GUI), graphical user interface wizard, or command-line interface (CLI).
Operating systems can be abstracted through the use of virtual machines and hypervisors, which make running the OS and applications more efficient by distributing computing power.
Modern operating systems have very high requirements to be considered reliable and secure.
Thus, they are usually implemented as a complex, multi-user computer network.
Not all operating systems are suitable for use in every situation, since they often use a specific processor architecture or specific capabilities of a particular computer system.
For example, a hypervisor (which, like an operating system, is only one part of a larger system) must restrict how the operating system can be used in a particular computer system.
Nevertheless, operating systems, in general, provide many services that make computing more efficient, reliable, flexible, flexible and robust.
Many modern operating systems can be run on several processors simultaneously, including thousands of processor cores.
Operating systems developed before the microcomputer era have typically used single-tasking operating systems, like DOS, and parallel operating systems that do not perform any sort of schedule prior to an interrupt, such as the Mach and Net/2 operating systems.
Modern operating systems typically offer multiple CPU or several CPU configurations, which may run concurrently on the same CPU or on different CPU architectures.
For example, Windows uses Windows NT for its "real-time" kernel, which is preemptive and has a large amount of memory for modern applications.
OS designs may share common features in common by means of portable shared libraries, allowing an application written in one programming language to operate on an object in a different programming language, and allow application developers to work with multiple programming languages at the same time.
Since computers have become more powerful over time, many operating systems are built to use a higher level of abstraction (for example, Windows Vista, Windows 7, and macOS Sierra).
Programs are typically developed in the programming languages that they will support, although some operating systems allow developers to write programs in languages other than their primary one (like Linux).
Some operating systems provide environment variables (codice_1 and codice_2 in some systems).
A typical programming language might have an operating system like Windows.
Some languages like Common Lisp have software operating system.
Operating systems were first conceptualized and developed by Elmer H. Anderson and Joseph M. Bessette at Bell Labs in 1954, shortly after the first IBM 704 computers, designed by Ed Roberts, were introduced into service at Bell Labs in 1954.
