The term "swappable" refers to something that can be replaced or interchanged with another item. This often applies to components in a device, such as a computer or phone, where certain parts like batteries, memory cards, or even entire modules are able to be removed and replaced by the user without needing any special tools or knowledge beyond basic disassembly skills. Swappable also refers to items that can be traded, bartered, or exchanged for something else of equal value, as in a swap meet or trade show where people bring their own goods to sell, buy, or exchange with others. In essence, the term "swappable" means capable of being replaced or interchanged, and is often used to describe items that are modular, replaceable, or customizable.
