Acumulator: -This is an 8-bit register that is used to perform airthematic and logic operation. It stores the output of any operation. It also functions as registers for I / O access.

Temporary Register: -This is an 8-bit register that is used to store the data on which the Accumulator is working. It is also called Operator Registry as it provides operands to ALU.

Registers: - These records are general purposes. The microprocessor consists of 6 general-purpose 8-bit registers, each named B, C, D, E, H, and L. Generally, these registers are not used to store data. given permanently. It carries 8-bit data. These are used only during the execution of the instructions.

These registers can also be used to carry 16-bit data by pairing 2 registers. The valid register pairs available are BC, DE HL. We can not use other pairs except BC, DE and HL. These registers are programmed by the user.
