Course Description

O Ghosh !! I just cannot shout-out more how important TIMERS are in almost all applications or projects. Timers are used to schedule events to be triggered or fired in future. How have you been doing this till now ?

Timers Use case Scenarios :

1. Firing One time future Event : Delete something after 100 seconds

2. Firing Repeated Regular future Events : Send packet to machine X after every 5 seconds

3. Periodic Waits : Try something 5 times at an interval of 3 seconds


How would you design a timer ?   PET Question for interview. So better prepare for it.


About this Course This is short project based course, yet important course to cover Data Structures and Algorithms involved in designing efficient timers.  We shall be using C as a programming language, but you are free to use your favorite programming language. This course is Programming language agnostic.


Course Pre-requisite

If you can code in any programming language, that suffice.

You should familiar with basic data structures such as linked list and function pointers.

Basics of Multi-threading


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


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.


Warning : This course has auto system-generated subtitles which may not be perfect. Please disable subtitles as per your convenience.

Abhishek CSEPracticals

I have been engaged with coding and software for a decade now. I am a Networking developer at MNC. My rich working experience is backed by graduation from IIT Bombay as an MTech specialist. I am restless for more in-depth knowledge, and always working out the ways to integrate what I know in practical ways. I am always happy to train and encourage people on Udemy – the next-gen education platform.


I will help you to strengthen the networking concepts and fundamentals in a very practical way. I also hones in System Software Development, Linux System Programming and Network Software Development. I love to create courses on unique non-standard topics, and projects. Check my catalogue, you will find couple of project based courses which you can add to your resume.


You’ll complete assignments and work on a project where you’ll use all the theory. I make sure you build a proper understanding and that you’ll get all the questions and doubts answered. Let me take the privilege to guide you and bring useful additions to your resume !

As expected, added timer API into my learning space. Thank you, Abhishek Sir.

Superb. No words to describe.

By Joseph Walter on 11/6/2022

This course thus far has reinforced my understanding of Posix Timers, and made me aware of the Exponential Backoff type timers. I am pleased to also now be learning material new to me relating to a design that is scalable to a very large number of events, in which each timed event does not require its own timer thread, which cannot scale on a single machine which naturally has limits on the total number of threads that can be running simultaneously.

Great Course, For the ones who like to design and implement

By Kella Janardhanachari on 1/4/2022

I hope I can enjoy throughout all the sessions.

By Matthew Zito on 7/31/2021

Great course on a very important and traditionally difficult subject. Abhishek teaches it well, as usual. A major highlight of this course was learning about hierarchical timer wheels and event scheduling. This helped me better understand how things like the libuv event loop (famously used for non-blocking I/O in Node.js) works.

Great course .. Keep it up Abhishek and Team!!

By Shivam on 3/20/2020

A very good course for someone who has to build something meaningful in C.

By Aniket kumar on 2/6/2020

They have explained only concepts or overviews and provided their source code. It could be better if they also explain its implementation rather than only providing us source code. Not bad and also not too much good.

By Jack Li on 9/27/2019

Bless this man (Abhishek) and his courses on low-level/system programming!
