What is DSA?
DSA(Data Structures and Algorithms) is defined as a combination of two separate yet interrelated topics – Data Structure and Algorithms. DSA is one of the most important skills that every computer science student must have. It is often seen that people with good knowledge of these technologies are better programmers than others and thus, crack the interviews of almost every tech giant.
Data Structures : Ways to store data for different purposes. The choice of a data structure depends on the nature of operations and performance requirements. For example, there are different data structures using which we can store data in different ways for different operations like linear traversal, sorted traversal, quick search, insert and delete operations.
Algorithms : Steps that can be converted into programs to perform a specific task. Different algorithms serve different purposes like sorting, searching, etc. These algorithms use data structures to efficiently store and perform steps.

The term DSA stands for Data Structures and Algorithms, in the context of Computer Science.
What is Data Structure?
A data structure is defined as a particular way of storing and organizing data in our devices to use the data efficiently and effectively. The main idea behind using data structures is to minimize the time and space complexities. An efficient data structure takes minimum memory space and requires minimum time to execute the data. Please refer Data Structures for detailed learning of this topic.
What is Algorithm?
Algorithm is defined as a process or set of well-defined instructions that are typically used to solve a particular group of problems or perform a specific type of calculation. To explain it in simpler terms, it is a set of operations performed in a step-by-step manner to execute a task. Please refer Algorithms for detailed learning of this topic.
How to start learning DSA?
The first and foremost thing is dividing the total procedure into little pieces which need to be done sequentially.
The complete process to learn DSA from scratch can be broken into 4 parts:
- Learn about Time and Space complexities
- Learn the basics of individual Data Structures
- Learn the basics of Algorithms
- Practice Problems on DSA
