Fundamentals of hardware concepts

A computer system is made of a combination of hardware and software. The software consists of a set of instructions that instruct the computer to perform a task. It can be system software or application software. Whereas, hardware is the part of a computer that can be touched. In other words, computer hardware consists of the physical components of a computer. The internal parts of a computer are called components and the external hardware components are called peripherals.
