A process is a program in execution, and an integral part of any modern-day operating system (OS). The OS must allocate resources to processes, enable processes to share and exchange information, protect the resources of each process from other processes and enable synchronization among processes.
Process isolation is a set of different hardware and software technologies [1] designed to protect each process from other processes on the operating system. It does so by preventing process A from writing to process B. Process isolation can be implemented with virtual address space, where process A's address space is different from process B's ...
The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. An example of a basic software release life cycle
Process (computing) In computing, a process is the instance of a computer program that is being executed by one or many threads. There are many different process models, some of which are light weight, but almost all processes (even entire virtual machines) are rooted in an operating system (OS) process which comprises the program code ...
Process identifier. In computing, the process identifier (a.k.a. process ID or PID) is a number used by most operating system kernels —such as those of Unix, macOS and Windows —to uniquely identify an active process. This number may be used as a parameter in various function calls, allowing processes to be manipulated, such as adjusting the ...
Robot Operating System (ROS or ros) is an open-source robotics middleware suite. Although ROS is not an operating system (OS) but a set of software frameworks for robot software development , it provides services designed for a heterogeneous computer cluster such as hardware abstraction , low-level device control , implementation of commonly ...
The specific operating system and executable format determine how the dynamic linker functions and how it is implemented. Linking is often referred to as a process that is performed when the executable is compiled , while a dynamic linker is a special part of an operating system that loads external shared libraries into a running process and ...
The main purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug or malware within a process from affecting other processes, or the operating system itself. Protection may encompass all accesses to a specified area of memory, write accesses, or attempts to execute the ...
Google's offer of several open-source operating systems, of which Android and ChromeOS are the best known, has attracted some criticism, despite the similarity between this situation and that of Apple Inc.'s two operating systems, macOS and iOS. Steve Ballmer, Microsoft CEO at the time, accused Google of not being able to make up its mind.
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, called containers (LXC, Solaris containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), or jails ...
