TeX is a typesetting system created by Donald Knuth in the late 1970s to facilitate the production of high-quality technical and scientific documents. Designed to address the limitations of traditional publishing methods, TeX allows precise control over layout, mathematical notation, and typography, making it particularly popular among mathematicians, engineers, and scientists.

The system operates through plain text files combined with markup commands that specify formatting instructions. It processes these files to generate complex and professional-looking output in formats such as DVI (DeVice Independent) or PDF. TeX’s ability to accurately render mathematical expressions and symbols has made it the standard for scientific publishing, especially in disciplines that rely heavily on complex formulas.

TeX is open-source software and has inspired numerous extensions and macro packages, the most notable being LaTeX, which provides higher-level, user-friendly commands for document structuring and formatting. LaTeX simplifies document creation by offering predefined styles and templates, making it accessible to users without extensive typesetting knowledge.

The system's design emphasizes programmability and flexibility, allowing users to customize document layouts and automate formatting tasks. Its precise control and stability have contributed to its enduring popularity despite the emergence of newer typesetting tools.

Overall, TeX remains a foundational tool in academic publishing, digital typesetting, and document creation, valued for its accuracy, customizability, and ability to handle complex content. Its influence extends across various fields requiring meticulous presentation of technical material.
