Data Structure | MCQs

Explanation

The set of all possible values of data items is called domain.

A relational table's column structure is defined by a domain.

In a domain, there exist values.

They belong to a database domain, which is a column.

Explanation

Arrays store elements in a sequential (linear) order, where each item has a fixed position (index).

They allow efficient access to elements using their index, making them a linear data structure.

Explanation

The Push function is used to insert (add) an element onto the top of a stack.

In stack operations, Push = Insert, while Pop = Remove.

Explanation

The Entity Relationship (ER) Model visually represents entities, their attributes, and relationships in a database.

It is widely used in database design to define the logical structure before actual implementation.

Explanation

An element of an array is identified using its subscript (also called an index).

The subscript indicates the position of the element within the array, with most programming languages starting the index at 0.

Explanation

We cannot apply binary search algorithm to a sorted linked list, since there is no way of indexing the middle element in the list.
