Teaching aims : The students know the fundamental concepts of distributed systems and the structure of Web applications, including the underlying architectures, protocols and technologies.
They are familiar with the basic concepts and structures of operating systems. They also have an in-depth knowledge of multitasking/ multiprogramming, scheduling algorithms, classic and virtual main memory management and attendant algorithms, inter-process communication using signals, pipes, semaphores, and message passing.
The students are able to use command-line interfaces in a UNIX system (UNIX commands), to develop and implement simple web applications, to create shell scripts and use them to automate UNIX system (servers) work processes.
They know basics of Python programming and can use Python to develop dynamic Web applications.
