1. LINUX System : Lecture 1 Course Overview Bong-Soo Sohn Associate Professor School of Computer Science and Engineering Chung-Ang University

2. UNIX and LINUX UNIX In 1969/1971, initially written in Assembly, In 1973, rewritten in C by AT&T Bell labs. (portability) OS designed to be Programmer’s workbench multi-tasking, multi-user, time-sharing (interactive) platform-independent (portable) command line interpreter and pipe single command Widely used in servers, networked workstation

3. UNIX and LINUX LINUX In 1991, developed by Linus Torvalds UNIX-like OS (UNIX 의 한 종류 ) free and open source software Initially run on x86 (Intel) PC. Later, ported more server-level HW platforms and big computers such as mainframe and supercomputers LINUX also runs on embedded systems Android system is built on LINUX kernel used in many kinds of servers Database Servers, Web Servers, Business Servers,… Most internet environment is based on Client-server model Main Advantage Security, reliability, low cost, multi-user (permission) support

4. Course Overview Level : 3rd year CSE undergrad students Topics : How to use UNIX and it’s utilities in OS user perspective UNIX commands, utilities, shell, script, etc Internal structures and algorithms of UNIX kernel process, file/directory structure, memory, etc UNIX System Programming (UNIX system calls) (UNIX Servers : APM – Apache, PHP, MySQL) Objective Learn how to use UNIX/LINUX Understand internal structures of UNIX kernel Obtain the ability of programming under UNIX environment

5. Course Overview Textbook No required textbook for now We will also use on-line materials and some handouts. References Advanced Programming in the UNIX Environment (3rd Edition), W. Richard Stevens, Stephen A. Rago, Addison Wesley

6. Evaluation Midterm : 35% Finalterm : 35% Assignments : 25% Including around two programming assignments Class Participation : 5% You may get F grade if you miss (more than) ¼ of the whole classes Academic dishonesty (e.g. cheating, plagiarism, and etc.) will be taken seriously, and heavy penalty can be imposed.

8. Announcement Class Website http://cau.ac.kr/~bongbong/linux13 Class information such as lecture notes can be accessible through this website We will also use eClass to submit homework Programming Assignments We encourage to study and discuss together for doing programming assignments. However, you must do programming YOURSELF. You must not share any of source code with other students. Any kind of academic dishonesty will be taken seriously.
