RDT

RDT is a term that can refer to several different concepts, often depending on the context. One common meaning is Reliable Data Transfer. This refers to protocols and mechanisms designed to ensure that data sent over a network arrives at its destination correctly and in the intended order, even in the presence of errors or disruptions. Examples of RDT protocols include those used in TCP (Transmission Control Protocol) which provides reliable, ordered, and error-checked delivery of a stream of bytes. These protocols typically employ techniques like acknowledgments, retransmissions, and sequencing to achieve reliability.

Another interpretation of RDT is "Rapid Diagnostic Test." In a medical or laboratory setting, RDTs are tests that provide quick results, often within minutes or hours, to diagnose the presence or absence of a specific condition, disease, or substance. These tests are often designed for use at the point of care, meaning they can be performed near the patient or at the site of testing without requiring specialized laboratory equipment. Examples include rapid antigen tests for infectious diseases or pregnancy tests.

In the context of software development or testing, RDT might stand for "Regression Test Development" or a similar phrase related to the process of creating and managing regression tests. Regression testing is a type of software testing that verifies that recent code changes have not adversely affected existing functionality. The "RDT" in this case would refer to the practices and tools used to build a suite of tests that can be repeatedly executed to catch unintended side effects. The specific meaning of RDT is therefore heavily reliant on the domain in which it is being used.
