There are several types of hardware components that make up a computer system. This includes desktop computers, laptops, tablets, and mainframe/server computers. Desktops fit on a desk while laptops are portable with integrated screens and batteries. Tablets have touchscreens and can access the internet via SIM cards. Mainframes are large, expensive systems that support many users simultaneously. Computers also have various input devices like keyboards, mice, scanners, and joysticks to enter data. Output devices display and present the processed data, such as monitors, printers, speakers and projectors.
