[1] Custom footer
Many themes have only limited space ( In this example - Boadilla) limited space for displaying the title, author, institute information... in the footer. So when they are displayed, the footer section cant hold whole information.
\documentclass{beamer}
\usetheme{Boadilla}
\title{Beamer - Introduction to \LaTeX presentation making}
\author{Jestin Joy}
\institute{College of Engineering Chengannur}
\begin{document}
\begin{frame}
\titlepage
\end{frame}
\begin{frame}{Introduction}
Hello World.

Beamer provides an option tag to replace with our own version of author, institute information so that it did not result in overlapping display
\documentclass{beamer}

\title[Latex Intro]{Beamer - Introduction to \LaTeX presentation making}
\author{Jestin Joy}

\end{frame}
\begin{frame}{Introduction}
Hello World.
\end{frame}
\end{document}
