WebA memory buffer register (MBR) or memory data register (MDR) is the register in a computer's CPU that stores the data being transferred to and from the immediate access storage. It contains a copy of the value in the memory location specified by the memory address register.It acts as a buffer, allowing the processor and memory units to act … WebIn computing, the instruction register (IR) or current instruction register (CIR) is the part of a CPU's control unit that holds the instruction currently being executed or decoded. In simple processors, each instruction to be executed is loaded into the instruction register, which holds it while it is decoded, prepared and ultimately executed, which can take several steps.
WebConclusion. There are several types of computer registers, such as accumulator, MDR, MAR, and more. All of these registers serve a specific purpose during the execution of an instruction, such as data-related processes, data retrieval or storage, and a variety of other tasks.
