  2. Process management (computing) - Wikipedia

    en.wikipedia.org/wiki/Process_management_(computing)

    Execution of process creation system call by a running process. A user request to create a new process. Initiation of a batch job. When an operating system is booted, typically several processes are created. Some of these are foreground processes, that interact with a (human) user and perform work for them.

  3. Process control block - Wikipedia

    en.wikipedia.org/wiki/Process_control_block

    A process control block ( PCB ), also sometimes called a process descriptor, is a data structure used by a computer operating system to store all the information about a process . When a process is created (initialized or installed), the operating system creates a corresponding process control block, which specifies and tracks the process state ...

  4. Process (computing) - Wikipedia

    en.wikipedia.org/wiki/Process_(computing)

    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 ...

  5. Thread (computing) - Wikipedia

    en.wikipedia.org/wiki/Thread_(computing)

    A process with two threads of execution, running on one processor Program vs. Process vs. Thread Scheduling, Preemption, Context Switching. In computer science, a thread of execution is the smallest sequence of programmed instructions that can be managed independently by a scheduler, which is typically a part of the operating system.

  6. Base and bounds - Wikipedia

    en.wikipedia.org/wiki/Base_and_bounds

    In computing base and bounds refers to a simple form of virtual memory where access to computer memory is controlled by one or a small number of sets of processor registers called base and bounds registers. [1] In its simplest form each user process is assigned a single contiguous segment of main memory. The operating system loads the physical ...

  7. Process architecture - Wikipedia

    en.wikipedia.org/wiki/Process_architecture

    Process architecture. Process architecture is the structural design of general process systems. It applies to fields such as computers (software, hardware, networks, etc.), business processes ( enterprise architecture, policy and procedures, logistics, project management, etc.), and any other process system of varying degrees of complexity. [1]

  8. Exokernel - Wikipedia

    en.wikipedia.org/wiki/Exokernel

    Exokernel is an operating system kernel developed by the MIT Parallel and Distributed Operating Systems group, [1] and also a class of similar operating systems. Operating systems generally present hardware resources to applications through high-level abstractions such as (virtual) file systems. The idea behind exokernels is to force as few ...

  9. Process migration - Wikipedia

    en.wikipedia.org/wiki/Process_migration

    In computing, process migration is a specialized form of process management whereby processes are moved from one computing environment to another. This originated in distributed computing, but is now used more widely. On multicore machines (multiple cores on one processor or multiple processors) process migration happens as a standard part of ...
