CST311: Journal 1

This week I learned about computer networking and the internet. I learned about the hardware such as switches, routers, servers, cables, and devices(computers, tablets, phones, etc) that are involved. I also learned about the topologies such as WAN and LAN.

I also learned about packet switching vs circuit switching.  Furthermore i learned about delays through packet switching such as processing delay, queuing delay, transmission delay, propagation delay, and end-to-end delay.

I also learned about protocol layering. This includes the application layer, transport layer, link layer, physical layer, and network layer.

I also learned about network attacks.
