In computer science, a queue is a collection of entities that are maintained in a sequence and can be modified by the addition of entities at one end of the sequence and the removal of entities from the other end of the sequence. By convention, the end of the sequence at which elements are added is called the back, tail, or rear of the queue ...
In a computer, an interrupt request (or IRQ) is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead. Hardware interrupts are used to handle events such as receiving data from a modem or network card, key presses, or mouse movements.
In computer science, an input queue is a collection of processes in storage that are waiting to be brought into memory to run a program. Input queues are mainly used in Operating System Scheduling which is a technique for distributing resources among processes.
Queue (abstract data type), a type of data structure in computer science Circular queue; Double-ended queue, also known as a deque; Priority queue; FIFO (computing and electronics) Load (computing) or queue, system load of a computer's operating system; Message queue; Queueing theory, the study of wait lines
Packets queuing in a FIFO (first in, first out) data structure.. A network scheduler, also called packet scheduler, queueing discipline (qdisc) or queueing algorithm, is an arbiter on a node in a packet switching communication network.
In computer science, a command queue is a queue that determines when a command is executed, usually by order of priority or on a first-in first-out basis. Instead of waiting for each command to be executed before sending the next one, a program will put all its commands in the command queue, freeing it to perform other functions while the queue is processed by the operating system.
In computer science, a pile is an abstract data type for storing data in a loosely ordered way. There are two different usages of the term; one refers to an ordered double-ended queue , the other to an improved heap .
In computer science, a circular buffer, circular queue, cyclic buffer or ring buffer is a data structure that uses a single, fixed-size buffer as if it were connected end-to-end. This structure lends itself easily to buffering data streams. [1] There were early circular buffer implementations in hardware. [2] [3]
