What is the purpose of expansion slots?

The purpose of expansion slots is primarily to allow for the installation of various cards that can expand the functionality of a computer system. These slots enable the user to add components such as graphics cards, sound cards, network interface cards, and other peripheral devices, thus enhancing the capabilities of the computer. This modular approach allows for upgrades and customization to meet specific user needs or performance requirements.

Expansion slots provide flexibility in designing and upgrading computer systems, as different users have different needs, whether for gaming, professional applications, or additional connectivity options. This ability to add cards means that a basic system can evolve into a more powerful and feature-rich machine without the need for replacing the entire motherboard or system.
