Explanation
### Why this is right
A motherboard is the main circuit board, so it houses and connects the computer’s central components. A bus is a communication route that carries data or signals between components, rather than a board or a processor. A Graphics Processing Unit (GPU), a processor designed for visual work, handles graphics-related tasks such as producing images and video.
### The concept
A **motherboard** is the large circuit board inside a computer; components connect to it directly or through connectors, allowing them to work together. A **bus** is a pathway within the computer that carries data or signals between parts, such as the processor and memory. A bus is not a physical board that houses components; it describes the route the signals travel. A **processor** carries out operations on data, and the GPU is specialized for the calculations needed to create or update visual output. The main processor can also handle general computing tasks, while the GPU is designed to work efficiently on graphics tasks.
### The pairs
| Item | Matches | Why |
|---|---|---|
| Motherboard | Main circuit board connecting system components | It provides the board and connections that let the computer’s central components communicate and work together. |
| Bus | Pathway carrying data or signals between components | It is the route signals travel inside the computer, not the board or the component doing the processing. |
| Graphics Processing Unit (GPU) | Component that processes graphics-related work | It is a specialized processor that performs calculations to render images, video, and other visual output. |
### Terms
