  2. 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 .

    en.wikipedia.org/wiki/Raspberry_Pi

    For systems that require a built-in real-time clock, a number of small, low-cost add-on boards with real-time clocks are available. [117] [118] The Raspberry Pi 5 is the first to include a real-time clock. [101]

    Real-Time Clock; RTC_A/B are 32-bit hardware counter modules that provide clock counters with a calendar, a flexible programmable alarm, and calibration. The RTC_B includes a switchable battery backup system that provides the ability for the RTC to operate when the primary supply fails. 16-bit timers

  5. Real-time clock alarm - Wikipedia

    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.

    en.wikipedia.org/wiki/Category:Computer_real...

    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.)

    RAM access tested using the mbw benchmark is 25% faster than the Raspberry Pi 3. SD card (microSD) access is about twice as fast at 37 MiB/s for buffered reads (compared to typically around 18 MiB/s for the Pi 3 [ 30 ] ) due to the Tinker Board's SDIO 3.0 interface, while cached reads can reach speeds up to 770 MiB/s.

  8. Real-time computing - Wikipedia

    en.wikipedia.org/wiki/Real-time_computing

    Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines". [2] The term "real-time" is also used in simulation to mean that the simulation's clock runs at the same speed as a real clock. Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds.

  9. Precision Time Protocol - Wikipedia

    en.wikipedia.org/wiki/Precision_Time_Protocol

    The Precision Time Protocol (PTP) is a protocol for clock synchronization throughout a computer network with relatively high precision and therefore potentially high accuracy. . In a local area network (LAN), accuracy can be sub-microsecond – making it suitable for measurement and control systems.
