  2. Futures and promises - Wikipedia

    en.wikipedia.org/wiki/Futures_and_promises

    In the Dojo Toolkit's Deferred API as of version 1.5, a consumer-only promise object represents a read-only view. [7] In Alice ML, futures provide a read-only view, whereas a promise contains both a future and the ability to resolve the future [8] [9] In .NET System.Threading.Tasks.Task<T> represents a read-only view.

  3. Exponential backoff - Wikipedia

    en.wikipedia.org/wiki/Exponential_backoff

    The throughput-delay results of the two retransmission methods were compared by extensive simulations and found to be essentially the same. [8] Lam’s model provides mathematically rigorous answers to the stability questions of slotted ALOHA, as well as an efficient algorithm for computing the throughput-delay performance for any stable system.

  4. Group delay and phase delay - Wikipedia

    en.wikipedia.org/wiki/Group_delay_and_phase_delay

    The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.

  5. Object lifetime - Wikipedia

    en.wikipedia.org/wiki/Object_lifetime

    In many contexts, including C++, C# and Java, an object is created via special syntax like new typename(). In C++, that provides manual memory management, an object is destroyed via the delete keyword. In C# and Java, with no explicit destruction syntax, the garbage collector destroys unused objects automatically and non-deterministically.

  6. Broadcast delay - Wikipedia

    en.wikipedia.org/wiki/Broadcast_delay

    Thus, a minute or so later, the broadcaster would again have full delay, often leaving the listener unaware that material had been deleted. In modern systems, a profanity delay can be a software module manually operated by a broadcast technician that puts a short delay (usually, 30 seconds) into the broadcast of live content.

  7. Quasi-delay-insensitive circuit - Wikipedia

    en.wikipedia.org/wiki/Quasi-delay-insensitive...

    A quasi-delay-insensitive circuit (QDI circuit) is an asynchronous circuit design methodology employed in digital logic design.Developed in response to the performance challenges of building sub-micron, multi-core architectures with conventional synchronous designs, QDI circuits exhibit lower power consumption, extremely fine-grain pipelining, high circuit robustness against process–voltage ...

  8. Transmission time - Wikipedia

    en.wikipedia.org/wiki/Transmission_time

    Roundtrip time = 2 × Packet delivery time + processing delay. In case of only one physical link, the above expression corresponds to: Link roundtrip time = 2 × packet transmission time + 2 × propagation delay + processing delay. If the response packet is very short, the link roundtrip time can be expressed as close to:

  9. Transmission delay - Wikipedia

    en.wikipedia.org/wiki/Transmission_delay

    In other words, this is the delay caused by the data-rate of the link. Transmission delay is a function of the packet's length and has nothing to do with the distance between the two nodes. This delay is proportional to the packet's length in bits. It is given by the following formula: = / seconds. where:
