Registers and RAMs

Registers are the smallest data-holding elements built into the processor itself. Registers are the memory locations that are directly accessible by the processor. The registers hold the instruction or operands currently accessed by the CPU.

Registers are the high-speed accessible storage elements. The processor accesses the registers within one CPU clock cycle. The processor can decode the instructions and perform operations on the register contents at more than one operation per CPU clock cycle.

Memory is a hardware device that stores computer programs, instructions, and data. The memory that is internal to the processor is primary memory (RAM), and the memory that is external to the processor is secondary (Hard Drive).
