Hardware is the equipments involved in the function of a computer. Computer hardware consists of the components that can physically handle. The function s in these categories of these components is typically divided into three main categories; input, output and storage. Components in these categories connect to central processing unit (CPU), the electronic circuitry that provides the computational ability and control of the computer, via wires or circuitry called a bus. The main difference between software and hardware can be assumed of their physical appearance as hardware are tangible whereas software are intangible.
