What is the primary purpose of data structures?

To store data in any format

To organize data in a specialized format for quick and effective processing (correct)

To slow down the retrieval of information

To limit the amount of data stored

In the context of data structures, what does the term 'static' refer to?

Data that is not stored in computer memory

Data that is only accessible by one user

Data that has a fixed format and size with specific memory locations (correct)

Data that is constantly changing

What is the significance of time complexity in data structures?

It increases the memory usage of data structures

It limits the running time or execution time of a program (correct)

It lowers the correctness of data

It ensures data is stored sequentially
