## Înainte de a începe cursul

Acesta este un curs practic pe parcursul căruia vom învăța despre [Internet](https://www.nsf.gov/news/special_reports/nsf-net/index.jsp), ce protocoale există în rețele și cum putem scrie programe pentru a interacționa cu rețelele.

O mare parte din exemplele de cod pot fi executate direct pe calculatoarele voastre (pe host). 

O parte din exemple utilizează containere de docker. Așadar, ca să puteți reproduce toate experimentele și demonstratoarele de la curs, veți avea de:

- [docker](https://docs.docker.com/install/linux/docker-ce/ubuntu/)

- [docker compose](https://docs.docker.com/compose/install/linux/)

- de preferat să fie instalate pe Linux sau MacOS
