Register is a ___________________.
Register is a Temporary storage unit within the CPU having dedicated or general purpose use.
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.
The x86-64 bit processor has the following registers: 16 general purpose registers each of 64 bit (including 2 Index registers and 2 Stack registers). 16 128-bit SSE registers. 6 16-bit segment registers.
General purpose registers in 8086 microprocessor. General purpose registers are used to store temporary data within the microprocessor. There are 8 general purpose registers in 8086 microprocessor. AX – This is the accumulator.
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.
There are various types of Registers those are used for various purpose. Some Mostly used Registers are Accumulator(AC), Data Register(DR), Address Register(AR), Program Counter(PC), Memory Data Register (MDR), Index Register(IR), Memory Buffer Register(MBR). Registers are used for performing the various operations.
