Course Description

This course is designed to challenge you as a programmer and new computer scientist at the University of Illinois Urbana-Champaign. Rather than the sand-boxed, contained, and simple problems of your previous courses that used significant scaffolding and pre-built libraries, you will be interacting with a much more complex environment: the entire system and even computing networks.

You will need to fully understand how memory is allocated, used, and re-used within a process.

You will also need to know how input and output can be optionally buffered between processes and files.

In short, it is time to remove the training wheels off and instead fling open the doors, welcoming you to the big, wide world of computing.

Oh, and did we mention the challenge of concurrency and solving asynchronous problems, so that your program can take advantage of the multi-core CPU inside each machine?
