Chapter 3

Case Study:

1.  Why does Akamai need to geographically disperse its servers to deliver its customer’s Web content?

 They keep copies in different locations so that one could retrieve a nearby copy which makes loading Web pages faster.

2.  If you wanted to deliver software content over the Internet, would you sign up for Akamai’s service? Why or why not?

I probably would not.  There is not a need for speed like with music, video and interactive request.

3.  What advantages does an advertiser derive from using Akamai’s service?  What kinds of products might benefit from this kind of service?

Because of their extensive network and software, “advertisers can deliver ads based on country, region, city, market area, area code, county, zip code, connection type, and speed.”   They can see real-time Web activity by visiting Akamai’s Web site.  The video streaming and large online retail businesses would benefit from Akamai’s service.

4.  Do you think Internet users should be charged based on the amount of bandwidth they consume, or on a tiered plan where users would pay in rough proportion to their usage?

I think a tiered plan would be fine if it does not make the internet too expensive and if it does not keep users from accessing high quality video streaming.  They could always charge additional if users anticipate or request higher consumption for any given month.

Questions:

1.  What are the three basic building blocks of the Internet?

The three important concepts of the Internet is:

1- packet switching; “a method of slicing digital messages into discrete units”

2- TCP/IP communications protocol; TCP-“establishes among sending and receiving Web computers”, “IP-provides the internet addressing scheme and is responsible for the actual delivery of the packets.”

3- client/server computing; “a model of computing in which client computers are connected in a network together with one or more servers.”

5.   What technological innovation made client/server computing possible?

“The development of personal computers and local area networks” made client/server computing possible.

10.   What is the goal of the Internet2 project?

“To facilitate the development, deployment, and use of revolutionary Internet technologies.”  It provided an environment to test and enhance the future of next-generation technologies.

15.    What are the basic capabilities of a Web server?

Basically a computer “attached to a network that stores files, controls peripheral devices, interfaces with the outside world-including the Internet-and does some processing for other computers on the network.”

20.  Why are mobile apps the next big thing?

Due to technology, internet usage by mobile phone and tablets have increased dramatically and many m-commerce are also increasing.  Mobil apps are useful in tapping into this burgeoning market that sees around $34 billion in mobile sales worldwide.  That’s what makes mobile apps the next big thing.

Projects:

The Internet of Things is the connecting of devices to the Internet and/or to each other.  The example from the book is the Apple Watch.  However there are others wearable devices and machines even vehicle. 

The Garmin Vivo is an activity wearable wrist device (watch) that tracks step.  It connects or syncs to your mobile phone to update information.  It displays your step, calories, distance and even monitors your sleep.  It also displays time, weather, GPS location, and alerts you of incoming messages or calls to your mobile phone.  However, you cannot access the Internet on the device like the Apple Watch.
