Answer 1

A peripheral is a device that connects to a computer and enhances its functionality but is not essential for the basic operation of the computer. Among the options provided, the following are considered peripherals:

- **Sound card**: While it can be integral to some systems for audio functions, it’s considered a peripheral since many computers have built-in sound capabilities.
- **Keyboard**: This is a classic example of a peripheral, as it is an external device used for input.
- **Graphics card**: This is often considered a core component as it handles graphical output, but it can also be seen as a peripheral in some contexts.

The CPU (Central Processing Unit) is not a peripheral; it is a fundamental component of the computer itself.

Thus, the best examples of peripherals in this context are **sound card, keyboard**, and **graphics card**. If you are to select only one, then the **keyboard** is the clearest example of a peripheral device.
