What type of a computer can be assembled using a monitor, a keyboard, a CPU, speakers, a printer and a mouse?

The description of a computer that includes a monitor, keyboard, CPU, speakers, printer, and mouse aligns perfectly with the characteristics of a desktop computer. Desktop computers are designed to be used in a stationary location and typically consist of separate components such as a CPU (the central processing unit), monitor, keyboard, and mouse, which are all connected together.

In contrast, a laptop computer integrates all these components into a single portable unit, which doesn't fit the description provided. A tablet computer, while also portable, primarily relies on a touchscreen for input and does not typically require a separate keyboard or mouse for basic functions. Smartphones are even more compact and designed for mobile communication, primarily functioning as communication devices with limited computing capabilities compared to the other types mentioned.

Thus, the correct answer reflects the standard configuration of a desktop computer, which allows for the assembly and use of the listed components.
