Frequently Asked Questions

Q1: How to define data?

A1: Data can be defined with the characteristics like – data should be traceable, atomic, clear, concise and accurate.

Q2: What are the types of data?

A2: Data type is a procedure to classify various types of data. This determines the values that can be used with the corresponding type of operations and data. Mainly, data types are of two types – Derived data type and built in data type

Q3: What are the basic operations of data?

A3: Basic operations of data include

  • Sorting
  • Deletion
  • Merging
  • Insertion
  • Searching
  • Transverse

Q4: What is the difference between build in and derived data type?


Built In data type Derived data type
A language has built in support Data types which can be independently implemented in one or the other way.
Example – Boolean, Character, Strings, Integers and Floating Build by the combination of built in data types and associated operations on them
Example – Array, Queue, List, Stack
