  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. 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.

  5. 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.

  6. 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 ...

  7. Delay-insensitive minterm synthesis - Wikipedia

    en.wikipedia.org/wiki/Delay-insensitive_minterm...

    Within digital electronics, the DIMS (delay-insensitive minterm synthesis) system [1] is an asynchronous design methodology making the least possible timing assumptions. Assuming only the quasi-delay-insensitive delay model the generated designs need little if any timing hazard testing. The basis for DIMS is the use of two wires to represent ...

  8. TCP delayed acknowledgment - Wikipedia

    en.wikipedia.org/wiki/TCP_delayed_acknowledgment

    If the application is transmitting data in smaller chunks and expecting periodic acknowledgment replies, this negative interaction can occur. To prevent this delay, the application layer needs to continuously send data without waiting for acknowledgment replies. Alternatively, Nagle's algorithm may be disabled by the application on the sending ...

  9. Thunk - Wikipedia

    en.wikipedia.org/wiki/Thunk

    In computer programming, a thunk is a subroutine used to inject a calculation into another subroutine. Thunks are primarily used to delay a calculation until its result is needed, or to insert operations at the beginning or end of the other subroutine.
