Questions and Answers

What is a data structure in computer science?

  • A data organization, management, and storage format chosen for efficient data access (correct)
  • A set of operations that can be applied to data without any specific format
  • An arbitrary arrangement of data with no defined relationships
  • A collection of random data values without any specific organization

    • What do data structures serve as the basis for?

  • Algebraic structures
  • Logical form of the data type
  • Abstract data types (ADT) (correct)
  • Physical form of the data type

    • Why are different types of data structures suited to different kinds of applications?

  • They have no specific purpose and can be used interchangeably
  • They are all equally efficient for any application
  • They are highly specialized to specific tasks (correct)
  • They are all designed for general-purpose use
