Internet and terms associated with it

The session talking about the internet was very interesting because the children hear and use so  many terms related to the internet and may not really know what it means. It was a good opportunity to talk about internet safety as well.

During the activity, some servers were given IP addresses and the programmer had to take a message to the designated server The number of packets the message had to be broken into, the domain name of the server and method of transfer (wifi, DSL.cable, fiber) was specified. The programmer used the DNS table to decipher which IP address it had to be sent to given the domain name.

The message sent by fiber could be carried with both hands holding it firmly. The message to be sent via DSL/cable had to be carried on the head so there was a chance of dropping. When the message was sent via wifi, it was not only carried on the head, but also, I blew on the packets so there was  a higher chance of losing packets.

It was a good lesson and everyone went back understanding how the internet works, the concept of data packets, DNS table, IP address, URL etc. We also discussed why wifi was used despite it having the chance of losing the packets.
