In telecommunications, round-trip delay (RTD) or round-trip time (RTT) is the amount of time it takes for a signal to be sent plus the amount of time it takes for acknowledgement of that signal having been received. This time delay includes propagation times for the paths between the two communication endpoints. [1]

A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix, which manages the sharing of system resources with a scheduler, data buffers, or fixed task ...

RTLinux is a hard realtime real-time operating system (RTOS) microkernel that runs the entire Linux operating system as a fully preemptive process. The hard real-time property makes it possible to control robots, data acquisition systems, manufacturing plants, and other time-sensitive instruments and machines from RTLinux applications.
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 .
A complete rewrite occurred for RT version 2.0 when Jesse started to work on RT full-time in 2001 and founded Best Practical Solutions. RT was used by Perl's CPAN, but because of declining use, a sunset date of March 1, 2021, was announced at the Perl NOC on December 4, 2020. rt.cpan.org will sunset on March 1st, 2021. Following a pushback from ...
RTX and RTX64 real-time software extensions to Windows combine the familiar user experience of Microsoft Windows (rich GUI, available drivers and software, ...) and the direct control of embedded hardware by providing hard real-time determinism and symmetric multiprocessing (SMP) abilities.
