Class Session: Thursday May 17, 2018
Basics: Networks
Don't forget about making blog posts or other parts of your Value Added grade component.
Preparations for this Networking Session
These Khan Academy videos serve as a great introduction to our Networking session. I want you to actively watch these videos before coming to class so read over the associate keywords I have listed on this page under each video link. Most of these keywords are at least briefly mentioned in the video.
This class will be collaborative in nature and you will have the opportunity to get to know your classmates better.
If I have found any other relevant links or videos associated with the term, that term will have an link to the source. if you see this arrow , then I have provided a related link that was not mentioned in the videos.
1. Wires Cables and Wifi (less than 7 minutes)
measuring data: binary, bit, byte, kilobyte, megabyte, gigabyte, terrabyte
data throughput and speed: bandwidth, bitrate, latency, requesting device
modes of transmitting data: copper wire, electricity, light, fiber optic cable, thread of glass, bounce angle, radio signal, wireless, signal degradation, wifi, satellite
2. IP addresses and DNS (less than 7 minutes)
Vint Cerf, Bob Kahn, internet, internet protocol (IP), network, ISP, IP address(es), IP hierarchy
⇒ Pinging a a domain to find the IP address:
computername:~ username$ ping unc.edu
⇒ Result:
PING unc.edu (152.2.64.93): 56 data bytes
early numbers are usually country numbers and regional numbers then subnetworks the the address of the device
IP4,IPv6, DNS, DNS server, zones, domain, top level domain (official list)
3. Packets Routers and reliability (less than 7 minutes)
IP packets, routes, cheapest path, TCP, TCP/IP ⇒TCP Joke
TCP inventory, acknowledgment, verification, sign, scaleable
4. HTTP and HTML (just at 7 minutes)
URL, server, HTTP, GET Request, HTML
HTTP POST, SSL, TLS, HTTPS
5. Encryption and Public Keys (less than 7 minutes)
encryption, Caesar's Cipher, algorithm, key, 256 bit keys ⇒ random key generator, symmetric encryption, asymmetric key, private key, public key
6. Cybersecurity and Crime (just at 5 minutes)
Cybersecurity viruses, DDOS attacks, phishing, hacker, botnet
top/reload prep panel
