The Complete Guide to Technology Acronyms

In the fast-paced world of technology, acronyms serve as shorthand for complex concepts and systems. Whether you're a seasoned developer or just getting started in IT, understanding these abbreviated terms is essential for effective communication and technical literacy. This comprehensive guide breaks down the most important acronyms across databases, networking, and programming domains.

Database Acronyms

SQL (Structured Query Language)

What it means: Structured Query Language What it's used for: SQL is a database query language specifically designed for getting data into and out of a relational database. It allows users to create, read, update, and delete database records through commands like SELECT, INSERT, UPDATE, and DELETE.

DBMS (Database Management System)
