What is RCD?

RCD can refer to several technologies, making it ambiguous without further context. Common possibilities include: * **Residual Current Device (RCD):** A safety device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock. It works by monitoring the current balance between the supply and return conductors of a circuit. If there is a difference, it indicates current leakage, potentially through a person, and the RCD trips, cutting off the power. * **Run-Length Encoding (RLE) Compression and Decompression.** A very simple form of data compression in which runs of data are stored as a single data value and count, rather than as the original run. This compression technique is used widely in image and video applications. * **Rapid Cycling Division Multiplying (RCD):** A division technique used in high performance CPUs. Without more information, it is impossible to determine the specific meaning of RCD.
