1. What is Tex?
TeX is a powerful automated typesetting system designed to allow anybody to produce high standard documents using minimal effort, and to provide a system that would give exactly the same results on all computers, at any point in time. It produces formatted output in a PDF file as well as in other formats.
TeX is a free software, and is available for all the operating systems. It is well documented as well as supported (visit http://tug.org and https://ctan.org).
TeX is a popular means of typesetting complex formulae, symbols, etc. It is popular in academia, especially in mathematics, computer science, linguistics, engineering, physics, chemistry, etc.
TeX is considered fairly difficult to learn on its own, and deals more with appearance than structure. In order to make it user friendly, there are several distributions (often known as macro packages or programs or engines) like LaTex, XeTeX, XeLaTeX, etc.
