A central processing unit (CPU), also called a central processor, main processor, or just processor, is the primary processor in a given computer. Its...

A zero register is a processor register that always returns the value zero and has no effect when it is written to. It is found in instruction set architectures...

computing, a quantum register is a system comprising multiple qubits. It is the quantum analogue of the classical processor register. Quantum computers...

An index register in a computer's CPU is a processor register (or an assigned memory location) used for pointing to operand addresses during the run of...

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...

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...
