What Is Datum in Data Structure?

Data structures are an integral part of computer science and programming. They provide a way to organize and store data efficiently, enabling faster access and manipulation. One important concept in data structures is the notion of a datum.


A datum, in the context of data structures, refers to a single piece of information or a value. It could be a number, a string, a character, or any other atomic unit of data that can be stored and processed by a computer program. In simpler terms, it is the basic building block of data.


To understand what a datum is, let’s consider some examples:

  • An integer such as 42
  • A string like “Hello World”
  • A character such as ‘a’
  • A boolean value – true or false

Each of these examples represents a single datum. In more complex scenarios, data structures can contain multiple datums organized in various ways for efficient manipulation.


The concept of datum is fundamental in data structures because it helps us understand how individual pieces of data fit together to form larger structures. By manipulating datums within these structures, we can perform operations on the entire collection efficiently.

Data structures like arrays, linked lists, stacks, queues, trees, and graphs all rely on the concept of datums to store and manipulate information effectively. Understanding how datums interact within these structures allows programmers to design optimal algorithms and solve complex problems.


In summary, a datum is a single piece of information or value used in data structures. It serves as the basic unit of data, allowing us to organize and manipulate information efficiently. By grasping the concept of datums, programmers can build powerful algorithms and solve real-world problems effectively.

So next time you work with data structures, remember that every piece of information you encounter is a datum!
