  • Outcome
  • Certification
  • In the free online course Operating Systems - Introduction to Synchronization you will learn 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 free Alison 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.

  • All Alison courses are free to study. To successfully complete a course you must score 80% or higher in each course assessments. Upon successful completion of a course, you can choose to make your achievement formal by purchasing an official Alison Diploma, Certificate or PDF.

    Having an official Alison document is a great way to celebrate and share your success. It is:

    • Ideal to include with CVs, job applications and portfolios
    • A way to show your ability to learn and achieve high results
