Key Concepts
For this test, you should understand the following terms and how they interrelate:
- execve semantics
- how command line variables are processed by execve
- how environment variables are processed by execve
- signal handlers
- concurrent operation with fork
- scheduler and relationship to system calls
- priority scheduling
- round-robin scheduling
- mutual exclusion
- semaphores
- basic pthreads
- System V init scripts versus launchd
- mounting filesystems
- loopback mounting
- sparse files
- basic filesystem implementation
- VFS abstraction
In addition to reading the notes, be sure to review the assigned readings! You will also need to know the material covered in Test 1.
Sample Questions
- Without errors, what does the execve system call return?
- Can a process modify its argument variables? Environment variables?
- Who calls a signal handler?
- If a parent and child process start printing "Parent\n" and "Child\n" to standard out, what will be the order of the output?
