We learn about hardware today. The motherboard is the main circuit board of the system unit. Expansion cards are for graphic, audio. The ports points out which peripheral attaches to the system unit so it can send or receive data.
Central Processing Unit also known as CPU interprets and carries out the basic instruction that operates a computer. It impacts the overall computing power and manages the computer's operation. There are two subcomponents of the CPU. a) Control Unit (CU) - extracts instruction from the memory and decodes and executes them. b) Arithmetic Logic Unit (ALU) - perform all arithmetic (mathematical calculations) and logical calculations (Boolean result-AND, OR, NOT, NAND, NOR, XOR, equivalence).
