The physical parts of a computer that you can touch. Like the engine, wheels, and body of a car - the actual components that make it work.
Your computer's screen, keyboard, memory chips, and processor are all hardware components.
Hardware is not a cloud service; it refers to the physical components (servers, storage devices, networking gear) that cloud providers own and operate in their data centers. Cloud services abstract this hardware so customers consume compute, storage, and networking without managing the physical equipment.
