Which of the following is the most quickly accessible storage?
The correct option is B Registers
Registers is the most
quickly accessible storage.
A processor register (CPU
register) is one of a small set of data holding places that are part of the
computer processor. A register may hold an instruction, a storage address, or
any kind of data (such as a bit sequence or individual characters). Some
instructions specify registers as part of the instruction.
Almost all computers,
whether load/store architecture or not, load data from a larger memory into
registers where it is used for arithmetic operations and is manipulated or
tested by machine instructions. Manipulated data is then often stored back to
main memory, either by the same instruction or by a subsequent one.
Saying "a (some)
processor has 32 registers that are 32 bits in size" won't get you
anywhere, there are countless numbers of processors. The 8086 had eight (more
or less general) 16-bit registers including the stack pointer, but excluding
the instruction pointer, flag register and segment registers.
