Week 7 Notes

How Internet Infrastructure Works: Jeff Tyson

-Internet is unique because it can’t be open by one person- it is a system of networks. (Hence the name internet, interconnected networks). The internet was created in 1969, and the internet society, a monitor of the internet, was created in 1992. It is a “network of networks”.
- Every computer with internet is part of the network.
- ISP- internet service provider, LAN- local area network. When you connect to one, you join their network
- POP: point of presence, NAP- Network Access Points
- Routers (little computers, networks couldn’t work w/o them) determine where to send information
- NSF: national science foundation, created backbone (T1 line to connect networks)
- IP Address- internet protocol- language of the internet
- Domain system names- automatically maps text name of IP address
- URL: Uniform Resource Locator is human readable domain name
- Names need to be unique
- Servers make the internet possible because they allow clients to use the networks
- Ports are more specific
*This article was very readable and user friendly. The examples and charts were also very helpful.

Sergie Brin and Larry Page on Google:
Video feed from 2004.
- Co-creators of Google talking about Google, search patterns, and the Google foundation. They also discussed their employees, which makes me really want to work for Google!
- It was a very impressive video because it visually allows you to see how the internet globally works. I had never seen an image like that, and it was really cool.


Andrew K. Pace. „Dismantling Integrated Library Systems“ Library Journal, vol 129 Issue 2, p34-36. 2/1/2004
- Libraries must adapt to changing technologies, updates on hardware and software programs are necessary.
- Competition of ILS systems (Integrated Library Systems) and a clash of old and new technology and the internet
- Includes compare/ contrast of the different systems and discusses the high levels of inoperability between systems
- Price plays big role, more expensive is better technology
- Commonplace is alliance with third party vendors (libraries don’t pay enough, and don’t usually have the most up to date technology?)
- Complete new system is often too complicated- but there is a need for standardization
- Interesting side note is that page two is scanned poorly; the whole picture is not visible.
- Nice, easy read and very informative.
