Understanding Data Structures

Which of these defines data structure?

• A way of organizing data items

• A type of algorithm

• A programming language

• A hardware component

What are the two broad categories of data structures?

• Primitive and Non-Primitive

• Linear and Non-Linear

• Static and Dynamic

• Simple and Complex

Which of these defines an array?

• A collection of heterogeneous elements

• A collection of homogeneous elements

• A type of linked list

• A type of tree structure

Which of these is the index of the first element in an array?

• 0

• 1

• 2

• It depends on the programming language

Which of these defines a stack?

• A collection of elements with LIFO order

• A collection of elements with FIFO order

• A type of array

• A type of tree

Which of these defines a queue?

• A collection of elements with LIFO order

• A collection of elements with FIFO order

• A type of stack

• A type of graph

Which of these defines tree in data structures?

• A linear data structure

• A non-linear data structure

• A type of array

• A type of stack

Which of these defines graph?

• A linear data structure

• A non-linear data structure

• A type of tree

• A type of stack

Which of these defines queue?

• A linear data structure

• A non-linear data structure

• A type of tree

• A type of stack

Which of these is NOT a definition of Primitive Data Structure?

• Structuring of a group

  of homogeneous data items.

• Basic structures and directly operated upon by the machine

  instructions.

• Integer, Floating-point number, Character constants, string constants,

  pointers etc, fall in this category.

• In general, there are different representation on different computers.
