15-213/15-503 Introduction to Computer Systems (ICS)
Summer 2025
- 15-213 Pittsburgh: Tue, Wed, Thu, Fri 12:30 PM-01:50 PM, SH 105,
Brian Railing
12 units (213), 6 units (503)
The ICS course provides a programmer's view of how computer systems
execute programs, store information, and communicate. It enables
students to become more effective programmers, especially in dealing
with issues of performance, portability and robustness. It also
serves as a foundation for courses on compilers, networks, operating
systems, and computer architecture, where a deeper understanding of
systems-level issues is required. Topics covered include:
machine-level code and its generation by optimizing compilers,
performance evaluation and optimization, computer arithmetic, memory
organization and management, networking technology and protocols,
and supporting concurrent computation.

TA office hours use an online queue
for both in-person and remote office hours.
- In person: Please specify a room number when adding yourself to the queue.
- Remote: Please specify a Zoom meeting ID and select the REMOTE tag in the queue.
- If you are remote but do not select the tag, we reserve the right to kick you from the queue as we cannot filter your question to the remote TA's.
Faculty office hours will be at the
locations and times listed at the bottom of this page.
