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
UNIX and LINUX

LINUX








In 1991, developed by Linus Torvalds
UNIX-like OS (UNIX의 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

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.
