To build a functional computer, a system must remember its state. This requires , where the output depends not only on current inputs but also on the history of past inputs.
Modern computers rely on billions of microscopic electronic components called . A transistor acts as an electronic switch. When voltage is applied to the control gate, current flows through the switch, completing a circuit. Basic Logic Gates This requires , where the output depends not
The Arithmetic Logic Unit (ALU) is born here—a chaotic city of gates wired together to perform addition, subtraction, and comparison. When you add 2 + 2 on a computer, you are not triggering a mathematical calculation in the abstract sense; you are sending voltage through a specific maze of transistors designed to toggle output wires in a pattern that corresponds to the number 4.
The OS is the master software that manages hardware resources. It schedules tasks for the CPU, allocates memory, and handles file storage.
