CST334 Module 6

 What to Write in your Journal Entry  Write a 1 - 2 paragraph description of what you learned this sixth week in CST 334 Topic: semaphores

This week was light on material but what we did have focused on semaphores. Semaphores are integers that are used to manage synchronization between threads. They are commonly used to manage critical sections between threads. Operating systems generally provide 2 methods alongside semaphores. Those being acquire and release methods such as SEM_POST and SEM_WAIT. Calling the SEM_WAIT method decrements the semaphore by 1 which then causes any other threads that call that same method to be blocked until the original thread calls the SEM_POST method which increments the semaphore and wakes a waiting thread.

CST489 / 499 Week 16

  For this week, please spend time browsing through your two years of journals and reflect on your overall experience and growth in the program. Some thoughts on future plans would be great, also.   This program has been an interesting two years, we've gone over so much material and yet I know I have so much more to learn just due to the nature of this field. I hope to continue to grow as I have these past 2 years and into a position where I can leverage my new skills.
