Register (computing)
In computing, a memory location that can be accessed rapidly; it is often built into the computer's central processing unit.
Some registers are reserved for special tasks – for example, an instruction register is used to hold the machine-code command that the computer is currently executing, while a sequence-control register keeps track of the next command to be executed. Other registers are used for holding frequently used data and for storing intermediate results.
