OBJECTIVES: During today's class I will be relate the significance of IP addresses to the functioning of the Internet

WORDS FOR TODAY:

• bit: A contraction of "Binary Digit"; the single unit of information in a computer, typically represented as a 0 or 1
• bandwidth: Transmission capacity measure by bit rate
• bit rate: (sometimes written bitrate) the number of bits that are conveyed or processed per unit of time. e.g. 8 bits/sec.
• latency: Time it takes for a bit to travel from its sender to its receiver.
• protocol: A set of rules governing the exchange or transmission of data between devices

WORK O' THE DAY:

Check out the curious (?) study described in Harvard Health Publishing on the impact of having a smart phone nearby...

Do you buy it?

Before we dive into the wonderful world of routers, let's make sure we have a plan in place for me to see ALL of your sources (sometimes they are hidden behind logons and such that I don't have access to).

Please email me a link of your for sources now, let's make sure they are all click-able. If they aren't we'll need to go to Plan B:

Go to the FULL Version/ PDF Version/Html version or otherwise complete version of your source:

• Print that to a pdf which will let you save it to a file.
• Save that file to your Google Drive
• Share it with me and put that link in the email note

OR

• Highlight the entire article (Ctrl-A in Windows)
• Copy that article out (Ctrl-C in Windows or Cmd-C in Apple)
• Paste that article into a Google Doc (Ctrl-V in Windows or Cmd-V in Apple)
• Save that file to your Google Drive
• Share it with me and put that link in the email note

Send that to me now (I'll record that as a 5 pt assignment)

Alrighty then... now here's an interesting conundrum (riddle) for you. Why are there so many MORE hops between the coffee shop (where I'm sitting now) and the district website then there were between me and Facebook (according to this ping I did a few years back)

(Oh and it just MIGHT be helpful to know just WHO them thar IP Addresses belong to, doncha think?)

Oh and just in case you didn't think to check the interweb, try THIS
