Random Access
actually register holds the data..there are 6 register which are temporary registers..program counter holds the address of next instruction to be fetched..instruction register holds the currently executed data...
Yes
Random Access Memory
During the fetch-decode-execute cycle, the Memory Address Register (MAR) holds the address of the memory location from which data is to be fetched or to which data is to be written. In the fetch phase, the MAR is loaded with the address of the next instruction to be executed. The Memory Data Register (MDR) then temporarily holds the data fetched from memory or the data to be written to memory. As the cycle progresses, the contents of the MAR and MDR are updated based on the memory operations required for executing the instruction.
The Ram - Random Access Memory temporarily holds programs and data while the computer is on and allows the computer to access that information randomly.
Fetch cycle is defined as a part of instruction cycle in which data is fetched from the memory pointed by Holds the address of a memory block to be read from or written to) and stores the data in MDR( a two-way register that holds data fetched from memory (and ready for the CPU to process) or data waiting to be stored in memory) for further processing. Instruction cycle= Fetch cycle+ Execute cycle
RAM or the processor cacheWhen the data and instructions reach the RAM they are operated on immediately.For data and instructions that the CPU is working on right at that time, these memory locations are called Registers. Many systems have dedicated registers just for EITHER data or instructions, while others have a set of registers which can be used for either, and still other CPUs have all three (data, instruction, and general-use registers).
MAIN MEMORY
memory
No,it does not because it is volatile memory.
A buffer is useful for temporarily storing data while it is being transferred between devices or processes. It helps to smooth out variations in data flow rates and prevent data loss by absorbing brief fluctuations. Buffers also help improve performance by allowing processes to operate independently at their own speeds.
MAR (Memory Address Register) holds the address of the memory location to be accessed or written to in the memory unit, whereas MDR (Memory Data Register) holds the actual data that is to be written to a memory location or data read from a memory location. MAR is used to specify the address, while MDR is used to temporarily store the data during memory operations.
