What are the two types of computer system units?

The two main types of computer system units are the desktop unit and the laptop unit. The desktop unit typically consists of separate components, including a monitor, keyboard, and a central processing unit (CPU) housed in a case, offering greater power and upgradeability. In contrast, the laptop unit is a compact, all-in-one device that integrates the display, keyboard, and hardware into a portable format, making it suitable for mobile use. Each type serves different user needs based on factors like space, performance, and portability.
