  2. HTTP persistent connection - Wikipedia

    en.wikipedia.org/wiki/HTTP_persistent_connection

    Under HTTP 1.0, connections should always be closed by the server after sending the response. [1]Since at least late 1995, [2] developers of popular products (browsers, web servers, etc.) using HTTP/1.0, started to add an unofficial extension (to the protocol) named "keep-alive" in order to allow the reuse of a connection for multiple requests/responses.

  3. Protective relay - Wikipedia

    en.wikipedia.org/wiki/Protective_relay

    A definite time over-current (DTOC) relay is a relay that operates after a definite period of time once the current exceeds the pickup value. Hence, this relay has current setting range as well as time setting range. An instantaneous over-current relay is an overcurrent relay which has no intentional time delay for operation. The contacts of ...

  4. Settling time - Wikipedia

    en.wikipedia.org/wiki/Settling_time

    Tay, Mareels and Moore (1998) defined settling time as "the time required for the response curve to reach and stay within a range of certain percentage (usually 5% or 2%) of the final value." [ 2 ] Mathematical detail

For additional questions specific to the email client, check the manufacturer’s website. Manufacturers cannot answer questions about your AOL Mail settings, or your AOL username or password.

  6. Shortest remaining time - Wikipedia

    en.wikipedia.org/wiki/Shortest_remaining_time

    Shortest remaining time being executed. Shortest remaining time, also known as shortest remaining time first (SRTF), is a scheduling method that is a preemptive version of shortest job next scheduling. In this scheduling algorithm, the process with the smallest amount of time remaining until completion is selected to execute. Since the ...

  7. Discrete-event simulation - Wikipedia

    en.wikipedia.org/wiki/Discrete-event_simulation

    When events are instantaneous, activities that extend over time are modeled as sequences of events. Some simulation frameworks allow the time of an event to be specified as an interval, giving the start time and the end time of each event. [citation needed] Single-threaded simulation engines based on instantaneous events have just one current ...

  8. Launch window - Wikipedia

    en.wikipedia.org/wiki/Launch_window

    A launch window indicates the time frame on a given day within the launch period that the rocket can launch to reach its intended orbit. [8] [9] This can be as short as a second (referred to as an instantaneous window) or as long as the entire day. The launch window can straddle two calendar days (for example, starting at 11:46 p.m. and ending ...
