Collectively this list of materials are known as the Computer Hardware. They interact with each other to produce the computers that we use today. Every computer system in the industry, is fundamentally exactly the same, and has the computer components inside. Similarly for troubleshooting other components a computer technician must have the knowledge of using different electronics gadgets.
