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 hold counters data instructions and addresses that the ALU is currently processing?
Registers
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.
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.
What 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 it called on the computer when the electronic components of the computer used to process data?
The CPU is in charge of processing the data. In more detail, the ALU (Arithmetic Logic Unit) is in charge of executing logical and arithmetic operations. The ALU is a component of the CPU.
IS Two important components of the system unit are the microprocessor and the hard disk?
The CPU comprised of three main parts: AlU(ARITHMETIC LOGIC UNIT):- Does the actual Logic comparisons that need to be processed. Control Unit:-Can execute and store the results coming out of ALU. Registers:- store the data that is to be executed next.
What makes up a CPU?
"The CPU is basically just the processing chip, but I could be wrong." You're partially right. Yes the CPU is a processing chip but they asked what is made up of. Physically: Cpu's are made from a silicon crystal which they essentially burn pathways and interconnections into and then fill those paths with copper. etc. Mathematically: CPU's consist of logical gates that turn on and off based on the data that they are fed from either the user or the software and then the user. And if you want even more detail a CPU contains whats called an ALU (arithmetic logic unit) which is fed data by the registers in which the ALU adds subtracts or shifts 0's in data (multiplication, division, etc) which is then stored in memory where it can be fetched and fed into it again by the registers. After the data has been essentially processed its fed onto a screen or some form of output. A cluster of these ALU's and corresponding registers form a core. A CPU i designed myself has 4 ALU's which can process 4 bits or 4 zeros at a time per ALU essentially and each of these ALU's communicate with each other thus forming a 4bit CPU core.
What is the full meaning ALU in computer?
Arithmetic Logic Unit - the place where all operations happen in a computer.Other units are:Memory - data and instructions kept here.Control - coordinates all units according to instructions.Input/Output - moves data and instructions in and out of the computer.
What is combinational alu?
combinational ALU
What is the difference between combinational alu and sequential alu?
There is one main difference between combinational ALU and sequential ALU. Combinational ALU depends only on present circuits, and sequential ALU depends on both the present and the past.
