Aging (scheduling)

In Operating systems, aging (US English) or ageing is a scheduling technique used to avoid starvation.

Central processing unit

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

Fair-share scheduling

Fair-share scheduling is a scheduling algorithm for computer operating systems in which the CPU usage is equally distributed among system users or groups, as opposed to equal distribution among processes.

Fernando J. Corbató

Fernando José "Corby" Corbató (born July 1, 1926) is a prominent American computer scientist, notable as a pioneer in the development of time-sharing operating systems.

FIFO (computing and electronics)

FIFO is an acronym for first in, first out, a method for organizing and manipulating a data buffer, where the oldest (first) entry, or 'head' of the queue, is processed first.

I/O bound

In computer science, I/O bound refers to a condition in which the time it takes to complete a computation is determined principally by the period spent waiting for input/output operations to be completed.

Lottery scheduling

Lottery scheduling is a probabilistic scheduling algorithm for processes in an operating system.

Multilevel queue

Multi-level queueing, used at least since the late 1950s/early 1960s, is a queue with a predefined number of levels.

Preemption (computing)

In computing, preemption is the act of temporarily interrupting a task being carried out by a computer system, without requiring its cooperation, and with the intention of resuming the task at a later time.

Queueing theory

Queueing theory is the mathematical study of waiting lines, or queues.

Round-robin scheduling

Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing.

Scheduling (computing)

In computing, scheduling is the method by which work specified by some means is assigned to resources that complete the work.

Starvation (computer science)

In computer science, starvation is a problem encountered in concurrent computing where a process is perpetually denied necessary resources to process its work.

Turing Award

The ACM A.M. Turing Award is an annual prize given by the Association for Computing Machinery (ACM) to an individual selected for contributions "of lasting and major technical importance to the computer field".
