A general-reason computer has four primary components: the arithmetic logic device (ALU), the Command unit, the memory, and also the enter and output devices (collectively termed I/O). These elements are interconnected by buses, typically crafted from groups of wires. Inside of Each and every of these components are 1000's to trillions of compact electrical circuits which can be turned off or on through an Digital switch.
