Detailed explanation-1: -The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it. Without a CPU, we could not run programs on a computer.
Detailed explanation-2: -A CPU executes code through a sequence known as the fetch, decode, execute cycle. Once a piece of code is loaded into RAM, the CPU will fetch its contents one by one, decode the contents into binary through the assembler, and then execute the code.
Detailed explanation-3: -The ALU has two main functions: It performs arithmetic and logical operations (decisions). The ALU is where calculations are done and where decisions are made.
