The third session of a computer networking workshop series was held yesterday evening at LAG Lab in Amsterdam. There were around ten attendees who listened to me talking about networking 101. I got some help from a guy who knew a lot about communications infrastructure in Britain. We lectured about these topics:
- Physical infrastructure and Internet overview
- The inner workings of a switch
- Why routers are necessary
- Digital vs. analog
- Circuit vs. packet switching
- Internet protocol suite
- MAC and IP addressing
- Frame and packet headers
- Classfull vs. classless addressing
- Counting in binary
- Subnet masks and CIDR
- Routing schemes
Yup, we covered a lot of ground in a mere 2,5 hours!
You can find the handouts in the download section of this article. The overview 'Map of the Internet' is editable in diagrams.net.
