Data Structure: What Is It?

A data structure is a logical or mathematical representation of how data organised. A data structure is, in essence, a means to arrange data so that computers can access it. It enables the processing of a significant volume of data in a comparatively quick length of time. Data structures are primarily used to lessen temporal and spatial complexity. An effective data structure uses the least amount of memory and executes in the fastest amount of time.

The following subjects, which often utilized in computer science, must cover if we assume that learning data structures should come first.

kinds of data structures

Arrays: An array is a group of identically typed items stored in a row or column of memory.
Connected Lists: It is a linear data structure in which the components linked to one another rather than being stored in consecutive memory regions.
Stacks: Adhere to the Last In First Out (LIFO) concept. The final piece in the stack eliminated first in this case.
Queues: The first thing stored eliminated first according to the FIFO principle (First In First Out).
Hash Tables: This kind of data structure contains values that each have a key associated with them. Data linked together and arranged hierarchically in a data structure called a tree.

The AVL Tree, Binary Search tree,  Splay tree, Binary tree, etc. are a few examples.

Heaps: Storage stored in heaps, a particular tree-based data structure also known as a binary heap.

Graphs: It’s made up of a collection of nodes and edges that link them.
