In mathematical queueing theory, Little's law (also result, theorem, lemma, or formula [1] [2]) is a theorem by John Little which states that the long-term average number L of customers in a stationary system is equal to the long-term average effective arrival rate λ multiplied by the average time W that a customer spends in the system.
In a binary exponential backoff algorithm (i.e. one where b = 2), after c collisions, each retransmission is delayed by a random number of slot times between 0 and 2 c − 1. After the first collision, each sender will wait 0 or 1 slot times. After the second collision, the senders will wait anywhere from 0 to 3 slot times . After the third ...
In computer architecture, a delay slot is an instruction slot being executed without the effects of a preceding instruction. [1] The most common form is a single arbitrary instruction located immediately after a branch instruction on a RISC or DSP architecture; this instruction will execute even if the preceding branch is taken.
[1] Shortest job next can be effectively used with interactive processes which generally follow a pattern of alternating between waiting for a command and executing it. If the execution burst of a process is regarded as a separate "job", the past behaviour can indicate which process to run next, based on an estimate of its running time.
The delay locked loop is a variable delay line whose delay is locked to the duration of the period of a reference clock. Depending on the signal processing element in the loop (a flat amplifier or an integrator), the DLL loop can be of 0th order type 0 or of 1st order type 1.
Since the XMODEM protocol defined a limit of ten NAK s to abort a send, and each packet might take a second to send, this meant there was a ten second delay where the sender continually sent data that was simply ignored. Some implementations had added the ability to send a CAN instead of ACK or NAK at the end of a received packet to indicate an ...
Longest-processing-time-first (LPT) is a greedy algorithm for job scheduling.The input to the algorithm is a set of jobs, each of which has a specific processing-time.There is also a number m specifying the number of machines that can process the jobs.
A Round Robin preemptive scheduling example with quantum=3. Round-robin (RR) is one of the algorithms employed by process and network schedulers in computing. [1] [2] As the term is generally used, time slices (also known as time quanta) [3] are assigned to each process in equal portions and in circular order, handling all processes without priority (also known as cyclic executive).
