  2. Clock synchronization - Wikipedia

    en.wikipedia.org/wiki/Clock_synchronization

    Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates. There are several problems that occur as a result of ...

  3. Real-time clock - Wikipedia

    en.wikipedia.org/wiki/Real-time_clock

    A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in personal computers , servers and embedded systems , RTCs are present in almost any electronic device which needs to keep accurate time of day .

    Real-time clocks are electronic devices designed to provide system time, and thereby wall-clock time, to a computer system. (Contrast this with clock signals , designed to provide timing for electronics themselves.)

    The first version of Microsoft Schedule+ as bundled with version 3.0 of the Microsoft Mail email client will refuse to work [needs update] with years greater than 2020 or beyond, due to the fact that the program was designed to operate within a 100-year time window ranging from 1920 to 2019. As a result, the date can only be set as high as 31 ...

    en.wikipedia.org/wiki/Real-time_clock_alarm

    A real time clock alarm is a feature that can be used to allow a computer to 'wake up' after shut down to execute tasks every day or on a certain day. It can sometimes be found in the 'Power Management' section of a motherboard 's BIOS / UEFI setup.

  7. apk (file format) - Wikipedia

    en.wikipedia.org/wiki/Apk_(file_format)

    To make an APK file, a program for Android is first compiled using a tool such as Android Studio [3] or Visual Studio and then all of its parts are packaged into one container file. An APK file contains all of a program's code (such as .dex files), resources, assets, certificates, and manifest file. As is the case with many file formats, APK ...

  8. Clock drift - Wikipedia

    On average the faster crystal will then tick 10,000 times for each time the slower one ticks. But since clock crystals are not precise, the exact number of ticks will vary. That variation can be used to create random bits. For instance, if the number of fast ticks is even, a 0 is chosen, and if the number of ticks is odd, a 1 is chosen.

  9. Apple II system clocks - Wikipedia

    en.wikipedia.org/wiki/Apple_II_system_clocks

    The No-Slot Clock, also known as the Dallas Smartwatch (DS1216E), [1] was a 28-pin chip-like device that could be used directly in any Apple II or Apple II compatible with a 28-pin ROM. Dallas Semiconductor produced the device as an easy implementation for a real-time clock for a variety of applications.
