Be Wired

1
Be Wired!

• (Which Wire?)
• Internet Connection Options and Comparisons
• Eric Hawley
• Utah State University Extension

2
Step 1

• Locate providers
• Telephone (Quest, etc)
• Cellular Phone (Verizon, ATT, etc)
• Cable (Comcast, etc)
• Satellite (Starband, etc)
• Independents (???)

3
Step 2

• Determine product availability, bandwidth,
  pricing options.
• Telephone Providers Dial-Up, ISDN, DSL
• Cellular Providers CDMA (V), GPRS (A,S)
• Cable Providers Cable Internet Svc.
• Sat. Providers Sat. Internet Svc.
• Independent Providers Wireless, ?

4
Step 3

• Select the product that represents the best
  balance between bandwidth, services, and price to
  meet your needs.
• (Simple, huh?) ?

5
Meet Your Needs

• How many computers?
• Percentage of time downloading vs. uploading for
  each?
• Does any computer/server you are connecting to
  the internet need to be seen from the OUTSIDE?
  (Web server?)
• How fast is fast-enough?

6
Bandwidth

• Never underestimate the bandwidth
• of a station-wagon full of mag tapes.
• 6250bpi, 2500 feet, 25MB, 200 in a wagon, 4.7G
  (1dvd), 79mph, 10mbps

7
Bandwidth (k,m,g,b,B)

• (Watch Your Bs, or do I mean bs?)
• (Metric, we love it k,m,g)
• Typically in mbps or kbps.
• (8b) in (1B)
• (1000k or K) in (1m or 1M)
• Dial up 40k.. (really 40kbps)
• Compare to 1.5m (really 1.5mbps)

8
Bandwidth Bewares

• There may be separate speed limits for
• UPLINK and DOWNLINK
• May pay more for
• GUARANTEED BANDWIDTH
• Marketers like to use
• THEORETICAL BW RATINGS

9
Price

• Not always related directly to Bandwidth
• Also linked to services and market
• Typically there are TWO things to buy The
  LINE and the ISP.

10
Services

• Are you really buying JUST internet service
  (through an ISP) and a line?
• IP Addresses
• Static? -Dynamic?
• Public? (routable) -Private? (non-r)
• One? -Many?
• Domain Names Web Hosting

11
