\begin{frame}{What is Linux?}
47+
\begin{minipage}[t]{0.6\textwidth}
48+
Linux is a generic name for a family of open-source Unix-like operating systems based on the Linux kernel. \\
49+
Linux operating system is widely used in servers, personal computers, embedded systems, and other devices. It is built on the Linux kernel, which is the core of the operating system that manages communication between hardware and software.

\section{History}
91+
92+
\begin{frame}{UNIX}
93+
\begin{itemize}
94+
\item Developed in AT\&T's Bell Labs in late 60s
95+
\item Designed as a multiuser, multitasking system
96+
\item Influenced many subsequent operating systems
97+
\end{itemize}

\begin{frame}{UNIX history}
102+
\begin{itemize}
103+
\item Origins at Bell Labs (1969-1970)
104+
\item UNIX Expansion (1970s)
105+
\begin{itemize}
106+
\footnotesize
107+
\item Version 1 (1971): The first official version was released
108+
\item Academic Adoption: By 1973, UNIX had been rewritten in C, making it more portable
109+
\item Influence on Academia: UNIX became a popular teaching and research tool in academic circles, and many computer science students learned programming in this environment
110+
\end{itemize}
111+
\item Commercialization and Fragmentation (1980s)
112+
\begin{itemize}
113+
\footnotesize
114+
\item Version 1 (1971): AT\&T began to commercialize UNIX more aggressively
115+
\item System V (1983): AT\&T's commercial version of UNIX, called System V, became a standard for many commercial UNIX systems. However, BSD continued to evolve separately, leading to a fragmentation of UNIX versions
116+
\end{itemize}
117+
\item UNIX Wars (1980s-1990s)
118+
\begin{itemize}
119+
\footnotesize
120+
\item Many different versions appeared
121+
\item POSIX Standard was introduced
