What is Data Structure & Algorithms?

Data structure and algorithms are closely related concepts in computer science that deal with the organization and manipulation of data.

A data structure is a method for arranging and keeping track of data in a computer so it can be efficiently accessed and changed. Common data structures include queues, stacks, linked lists, and arrays.

An algorithm collects all instructions to complete a task or solve a problem. Algorithms are frequently used when processing or manipulating data using a particular data structure.

Data structures and algorithms are essential concepts in computer science because they form the basis for many vital operations that computers perform. Understanding and effectively using different data structures and algorithms is necessary for anyone in computer science or related fields.

Data structures are pre-programmed structures that store ordered data to make various actions on it simple. It stands for the knowledge of how data should be stored in memory. It should be created and used to make things small and more effective.

Applications today frequently encounter three issues as they get more complicated and data-rich.

Consider a store with a 1 million item (106 items) inventory. Every time the application needs to search for something, it must do so across 1 million (106) things, which slows down the search. In addition, the search will become slower as data volume increases.

Despite being extremely fast, processor speed decreases once the data expands to billion records.

Multiple queries Even the fastest web server can fail when searching the data because thousands of users can do it at once.
