- Prepare for IPC based interview Questions
- Design a Linux process which could harness benefits of various IPC Mechanism at the same time
- Basic C is essential
- Basic knowledge Operating System shall be good
- Zeal and Enthusiasm to learn
About 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 exchange data with each other. We will go through the concepts in detail behind each IPC mechanism, discuss the implementation and design and analyse the situation where the given IPC is preferred over other.
We also discuss how application should be designed to use IPC facility 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.
For 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 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 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 finger tips.
It shall be advantageous if you know a little of C and OS. We designed this course assuming 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 same as mine !
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 another course on Linux RPCs where you will learn how to implement RPCs from scratch.
Programming Language used In this course :
We have a 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 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 do not suggest taking 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.
Note 1: If you have done my other course "Network Concepts and Programming from Scratch", then there are some topics in this course (In Module 1 - Unix Domain Sockets) which overlap. However, it is mandatory to make overlapping topics as part of this course to make this course a complete unit. Please feel free to watch those topics with 2x speed Or skip altogether as per your convenience.
Note 2: 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 a great value for you.

This Lecture is for those who are absolute beginners with Linux and have no prior knowledge with Linux Installation. This course do not demands user to use Linux OS. All Assignments can be done on Windows platform also, however, it is recommended to use Linux for Development work. Please switch if you are still stuck with windows.
Pls go through this tutorial which will tour you through the Linux installation steps and supporting softwares. Those who are already using Linux can safely skip this Section. Pls excuse, sound quality of this youtube VDO isnt that great.
