How to practice computer networking at home ?

Question

I'm taking the "The Bits and Bytes of Computer Networking" on Coursera, But i don't know how to apply the course to the real life projects

So my questions are:
How to practice networking?
How to gain experience in networking before applying to a job (To be job-ready) ?
And what are the roles of real-life network specialist ?
