The course Operating Systems - Introduction to Synchronization will teach you about Inter-process Communication (IPC) for process communication and data sharing. The course also introduces you to shared memory, message passing and signals all methods for IPC.

You will learn about the critical section and problems accessing the critical section. You will learn about ways to access the critical section and how hardware can also help accessing it.

The course begins by introducing you to Inter Process Communication (IPC). You will learn the main ways processes share data and communicate with each other. The course then introduces process synchronization and the Critical section, how to access the critical section using interrupts and build your own solution.

Next, you will be introduced to the bakery algorithm, which is another method for accessing the critical section. You will learn about how hardware can help with accessing the critical section, and about the test & set instruction, why Intel doesn’t support it but instead has its own xchg instruction. You will learn about Spinlocks, Mutexes and Semaphores and how they help with accessing the critical section.

This course will be of great interest to computer science students and computer engineers, and anyone who wants to learn about Inter-process communication in computer operating systems.

Perquisites: The learner will need to have completed the previous courses; Introduction to Operating Systems, Introduction to Memory Management, Introduction to Operating Systems Processes, Introduction to Operating Systems Interrupts and operating systems scheduling.

Having completed this course you will be able to: - Describe the different types of inter-process communication. - Explain process synchronization and the critical section. - Discuss possible solutions for multiple processes accessing the critical section. - Explain how the bakery algorithm works. - Discuss how hardware can help with the critical section problem. - Describe how spinlocks, mutexes and semaphores work.
