DSA stands for Data Structures and Algorithms. It is an essential computer science concept that involves organizing and manipulating data using different types of structures such as arrays, stacks, queues, linked lists, trees, and graphs.

These structures are used to solve different types of problems ranging from simple to complex such as sorting, searching, and graph traversal. DSA is a crucial part of any computer science curriculum and is used in a wide range of programming languages and applications.

Understanding DSA is critical for a computer scientist or data analyst to perform effectively in their role.
