A processor register is a quickly accessible location available to a computer's processor. [1] Registers usually consist of a small amount of fast storage, although some registers have specific hardware functions, and may be read-only or write-only.

En arquitectura de ordenadores, un registro es una memoria de alta velocidad y poca capacidad, integrada en el microprocesador, que permite guardar transitoriamente y acceder a valores muy usados, generalmente en operaciones matemáticas.
A control register is a processor register that changes or controls the general behavior of a CPU or other digital device. Common tasks performed by control registers include interrupt control, switching the addressing mode, paging control, and coprocessor control.
A register file is an array of processor registers in a central processing unit (CPU). The instruction set architecture of a CPU will almost always define a set of registers which are used to stage data between memory and the functional units on the chip.
The program counter (PC), commonly called the instruction pointer (IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register (IAR), the instruction counter, or just part of the instruction sequencer, is a processor register that indicates where a computer is in its program sequence.
An index register in a computer's CPU is a processor register (or an assigned memory location) [1] used for pointing to operand addresses during the run of a program. It is useful for stepping through strings and arrays. It can also be used for holding loop iterations and counters. In some architectures it is used for read/writing blocks of memory.
