After this module, students will be able to:

• Identify two possible results of running a C program that contains a race-condition.
• Predict the result of running a C program that uses interprocess communication.
• Predict the results of running a program that has installed a signal handler.
• Describe a process model for C and explain how it is influenced by the system calls fork, dup2, pipe, and exec.
• Implement a C function that relies on the representation of data at the bit level.
• Implement a C program that requires interprocess communication.
