Another name also referred to while discussing computer parts hardware is the computer hardware components. Computer hardware components are the single hardware parts that make up the whole computer system, such as the motherboard, processor or hard drive.
We also have peripherals hardware, which is similar to the hardware device with the exception that the peripherals hardware is an addition or an extension of the computer system, such as the printer, speakers or a digital camera. The word hardware originated from the construction industry years ago referring to the nuts and bolts used to increase the strength of the building materials being used and the term was coined for the computer systems describing the physical make up of the entire computer system.
Remember, Peripherals Hardware is just an expansion or extension of your computer system, hardware devices are designed to perform simple tasks, hardware components are the individual parts of your computer that make up t
