Genre: eLearning

What you’ll learn
You will be able to Design Application which require IPC
Choose the best IPC mechanism depending on the application requirement
Understand the Linux IPC programming interface
Understand Linux OS better and feel confident
Prepare for IPC based interview Questions
Design a Linux process which could harness benefits of various IPC Mechanism at the same time

This Course is about learning How Linux Processes Talk to each Other. This is a sub-domain of Linux System Programming. We shall explore various popular mechanism used in the industry through which Linux processes to exchange data with each other. We will go through the concepts in detail behind each IPC mechanism, discuss the implementation, and design and analyze the situation where the given IPC is preferred over others.

We also discuss how applications should be designed to use IPC facilities provided by underlying Linux OS.

You will have Assignments wherever possible, and throughout the course, there shall be one project in which you shall be incrementally applying the new IPC technique you have learned. Towards the end of the course, you would have practiced and applied all IPC techniques learned in this course.

Each IPC mechanism, we will have a detailed code walk in which I show you how actually a given IPC mechanism is implemented on sending and receiving side. When you would join the industry, from day 1 you will witness IPC concepts being applied all over the software in order to facilitate communication between different parts of the software.

Who should do this course ?

This course is meant for UG Computer science students, job seekers, and professional developers. This is a MUST do course for those who want to join MNCs as a developer in System Programming. In System Programming, almost all the time you have to use IPC to carry out data exchange between processes, therefore students graduating in computer science and looking to seek an opportunity in MNCs as a developer should have IPC concepts at his/her fingertips.


It shall be advantageous if you know a little about C and OS. We designed this course assuming the student is a complete beginner in Linux IPC and we raise the level of course gradually as we move from Basic to advance concepts wherever necessary.

Also, please just do not sit and watch my codes. Write your own codes, even if it is the same as mine!

Related Courses

RPC (Remote Procedure Calls) is another way of carrying out Inter-Process Communication between two processes running on separate machines in the network. You may also want to check my other course on Linux RPCs where you will learn how to implement RPCs from scratch.

Programming Language used In this course :

We have strong reasons to choose C as a language for this course:

IPC is a facility provided by the OS to developers to carry out data exchange between processes. Learning IPC using C helps you understand what is going on behind the scenes. C language really exposes the low-level details about how the system actually works. In System programming, C is the only language to be used and there is not even a remote substitute of this language when it comes to System programming.

No Third-Party libraries

Whatever logic you implement, you need to implement it from scratch. This course does not suggest taking the help of any third party library to get the jobs done. Use of external libraries completely defeats the purpose of the course. However, it is recommended to use third-party libraries for commonly used data structures such as linked lists/Trees/Queues, etc which saves a lot of time implementing these data structures.

Note1 : Though we use Linux to teach the IPC techniques, conceptually, IPC of Linux is not very different from other OS platforms such as windows, iOS, etc. So, if you are a programmer for other platforms, this course still holds great value for you.

Note2 : This Course talks about various techniques regarding exchanging data between processes, the other related topics such as process synchronization and locking is out of the scope of this course and will be covered separately.

Who this course is for:
Under graduate Computer Science Students
Post Graduate Students
Job Seekers in System programming Domain – Networking/Driver programming/Distributed Systems/IOT etc
