What is Computer Hardware ?  Computer hardware refers to the physical parts or components of a computer such as the monitor, mouse, keyboard, computer data storage, hard drive disk (HDD), system unit (graphic cards, sound cards, memory, motherboard and chips), etc. all of which are physical objects that can be touched.

Hardware Component The three major parts of a computer -- CPU, RAM, and Persistent Storage. These three are found in a laptop, or a smart phone, or a tablet.
