Detailed explanation-1: -Option 2 is the correct answer: Accumulator (ACC) stores the results of arithmetic and logical operations.
Detailed explanation-2: -The data to be processed by arithmetic and logic unit is stored in accumulator. It also stores the result of the operation carried out by the Arithmetic and Logic unit. The accumulator is also called an 8-bit register.
Detailed explanation-3: -Accumulator: It is a register used for storing intermediate results of larger computation. It keeps track of result of any arithmetic or logic operation.
Detailed explanation-4: -An arithmetic-logic unit is the part of a central processing unit that carries out arithmetic and logic operations on the operands in computer instruction words. In some processors, the ALU is divided into two units: an arithmetic unit (AU) and a logic unit (LU).
Detailed explanation-5: -In a computer’s central processing unit (CPU), the accumulator is a register in which intermediate arithmetic and logic results are stored.
