CRUD is an acronym that stands for Create, Read, Update, and Delete. It's a common term in computer programming and database management, referring to the four fundamental operations for managing data in persistent storage. CRUD operations are the basis for most applications that interact with databases, allowing users to add, retrieve, modify, and remove data.

Here's a more detailed breakdown:

• Create: Adding new data to a database or storage system.
• Read: Retrieving existing data from a database or storage system.
• Update: Modifying existing data within a database or storage system.
• Delete: Removing data from a database or storage system.
