It doesn't. Usually, the CPU general purpose registers provide input to the ALU, and the Accumulator receives the answer temporarily until it can be placed back into one of those registers.
Exactly how this is wired up varies widely with different CPU architectures, but in the theoretical model of an ALU, you specify which function you want, and the answer appears at the output as fast as the gates can operate. It is up to the CPU to store it somewhere.

What part of the processor is responsible for carrying out calculations?
The Arithmetic Logic Unit (ALU) is responsible for carrying out calculations in a processor. It performs arithmetic and logical operations on the data that is being processed.
What hold counters data instructions and addresses that the ALU is currently processing?
Registers
What are essential elements of CPU and their functions?
The essential elements of a CPU include the Arithmetic Logic Unit (ALU), Control Unit (CU), and registers. The ALU performs all arithmetic and logical operations, while the Control Unit directs the operation of the processor and coordinates the execution of instructions. Registers are small, high-speed storage locations that temporarily hold data and instructions being processed, enabling quick access and execution. Together, these components facilitate the CPU's primary role in executing instructions and processing data.
ARE the two smaller units of the processor are CU and ALU?
Yes, the two smaller units of a processor are the Control Unit (CU) and the Arithmetic Logic Unit (ALU). The CU manages and coordinates the activities of the processor, directing data flow and instruction execution. The ALU performs arithmetic and logical operations on the data processed by the CPU. Together, they enable the processor to execute instructions and carry out tasks.
Which component of the CPU is responsible for comparing the contents of two pieces of data?
ALU ( Arithmetic Logic Unit )
Which unit of computer performs arithmetic and logical functions?
The ALU (arithmetic logic unit) An ALU loads data from input registres, an external Control Unit then tells the ALU what operation to perform on that data, and then the ALU stores its result into an output register. Other mechanisms move data between these registers and memory.
Is the ALU a input device?
No, the Arithmetic Logic Unit (ALU) is not an input device. It is a digital circuit within a computer's CPU that performs arithmetic and logical operations on data. Input devices, such as keyboards and mice, are used to provide data to the computer, while the ALU processes that data.
How does ALU and CU work together?
The Arithmetic Logic Unit (ALU) performs arithmetic and logic operations on data, while the Control Unit (CU) manages the flow of data within the CPU. The CU directs the ALU on which operations to perform and coordinates the fetching, decoding, and executing of instructions in a program. Together, the ALU and CU work in harmony to process data and execute instructions in a CPU.
Does the control unit send data from the memory to the ALU for processing?
Yes, the control unit manages the flow of data within the CPU, including sending data from memory to the Arithmetic Logic Unit (ALU) for processing. It retrieves instructions from memory and orchestrates the movement of data, ensuring that the ALU receives the necessary operands for computation. The control unit plays a crucial role in coordinating these operations to execute programs effectively.
What is the function of alu?
ALUShort for Arithmetic Logic Unit, ALU is one of the many components within a computer processor. The ALU performs mathematical, logical, and decision operations in a computer and is the final processing performed by the processor. After the information has been processed by the ALU, it is sent to the computer memory.In some computer processors, the ALU is divided into two distinct parts, the AU and the LU. The AU performs the arithmetic operations and the LU performs the logical operations.

What is the role of the ALU in data processing?
The brain of any computer is its CPU. However, the brain of any CPU is the ALU. ALU short for Arithmetic And Logical Unit is the component that resides inside the CPU which processes data according to the given instructions && commands.
