Learners who have written some code in a high-level language and want to understand what happens underneath, and students preparing for systems, embedded or operating-systems courses.
Beginner level
Systems and Networks
How Software Meets Hardware
Learn C and how a computer really works: memory, pointers, bits and bytes, files, debugging with real tools and writing safe code, finishing with a command-line tool suite of your own.

At a glance
Basic programming ideas (variables, loops, functions) in any language. A Linux, macOS or Windows machine with WSL, the gcc compiler, make and a text editor. Comfort with the command line helps.
Pass the quizzes, complete the labs and submit your capstone. Everything is checked as you go and your certificate is issued the moment you finish.
What you will be able to do
- 01Write, compile and run C programs with warnings enabled and a Makefile
- 02Explain stack, heap, pointers and strings, and manage memory without leaks
- 03Represent numbers and text in binary and hexadecimal and use bitwise operations
- 04Debug with gdb, AddressSanitizer and valgrind
- 05Recognise and fix common memory-safety bugs and build a tested command-line tool

What you take away
An internship certificate with your skills on it.
Made for you automatically when you finish the last part, it names the internship programme, the level and the 40 hours, lists what you showed, and carries a number and a QR code. Anyone can check it on the NIBVEDA verification page, and it shows as withdrawn there if it is ever revoked.
- Proof you completed all 40 hours of this internship programme
- An Internship badge for your profile, CV or portfolio
- Not a job, a stipend or an academic degree, and it says so

Learn how an operating system works by using and building its pieces on Linux: processes and system calls, scheduling and threads, synchronisation, virtual memory, file systems and container isolation, with code and measurements.
- System calls
- Processes and threads
- Synchronisation
Build network servers from sockets up and understand them under load: TCP and TLS behaviour, event-driven servers with epoll, a safe HTTP implementation, performance methodology with profilers and tracing, and a measured, hardened network service.

Quick answers.
The policies have the full detail.
Is this a real internship?
It is a virtual internship programme: a structured, self-paced course built around a real project, with checked assessments and a certificate. It is not employment, it does not carry a stipend and it is not an academic or AICTE-approved qualification. What it gives you is verified, project-based evidence of skills.
How does self-paced work?
You start when you like and move at your own speed. Each part unlocks when you finish the one before it. There are no live classes and no deadlines. Your access is shown on each programme page.
How is my work checked?
Quizzes are marked as soon as you submit them. Labs use a tick-list of tasks. Intermediate and Expert programmes finish with a capstone that the NIBVEDA team reviews and either accepts or sends back with comments.
Can I get a refund?
Please read the refund policy before you buy. It explains when a refund is possible.
