Input Unit Accepts data and instructions from external sources (e.g., keyboard, mouse, scanner). Converts input into a form understandable by the computer. 2. Central Processing Unit (CPU) Also called the “brain” of the computer, it controls all operations. It includes: Arithmetic Logic Unit (ALU): Performs all arithmetic and logical operations.
