"Hardware" generally refers to the physical components of a computer or electronic system, as opposed to software, which consists of programs and data. Hardware includes a wide range of devices.Hardware can be classified into two main categories: input devices (which allow data to be entered into a computer) and output devices (which provide the results of the computer's processes). Additionally, there are internal components (housed within the computer case) and external components (connected externally, like printers or external hard drives). Advances in hardware technology play a significant role in the development and performance of computer systems. https://g.co/kgs/EWruJK
