The stack in digital computers is essentially a memory unit with an address register that can count. • The register that holds the address for the stack is
(Core Course Computer System Architecture unit-2) the content of the data register is stored at the current memory pointed by the stack pointer.

•Registers are faster than memory •Registers compiler technology has evolved to efficiently generate code for register files-E g (A*B) – (C*D) – (E*F) can do multiplies in any order vs stack •Registers can hold variables-Memory traffic is reduced so program is sped up (since registers are faster than memory)
