On a technical level, what are the three components of a processor/CPU?
On a technical level the top three components of a CPU are: 1. Arithmetic Logic Unit (ALU) The ALU is the part of a CPU that performs all arithmetic computations including addition, subtraction, multiplication, and division. The Arithmetic Logic Unit also performs all logical operations. The ALU is a literally the fundamental building block of the CPU, and even the simplest processors contain an ALU. Today’s modern CPUs and graphics processing units (GPUs) in graphic cards have very complex ALUs, and some contain a number of ALUs. In some CPUs an individual ALU is further divided into two units called an arithmetic unit (AU) and a logic unit (LU). Some processors even contain more than one AU. Normally the ALU has direct input and output access to the processor controller, main system memory (RAM), and input/output devices. In a nutshell an ALU works by loading data from what is called input registers, then an external Control Unit tells the ALU what operation to perform on that data,
