Week 7 Readings
Tyson, Jeff. http://computer.howstuffworks.com/internet-infrastructure.htm/printable
I didn't realize that there is a group (The Internet Society) that oversees how the internet is used.--- Another thought, isn't it amazing how a message can travel from one computer half-way across the world to another computer (through a network) in just a fraction of a second? --- I also was impressed with the step-by-step details of how your browser searches for URL or IP addresses when you type them in. What a great website!

Pace. „Dismantling Integrated Library Systems“ Library Journal, vol 129 Issue 2, p34-36. 2/1/2004 http://rt4rf9qn2y.scholar.serialssolutions.com/?sid=google&auinit=AK&aulast=Pace&atitle=Dismantling+integrated+library+system.(Infotech+Feature)(Industry+Overview).&title=Library+journal+(1976)&volume=129&issue=2&date=2004&spage=3&issn=0363-0277
This article was eye-opening for me; I didn't realize that libraries are starting to have frustrations with ILSs. I didn't know that inter-operability meant a more difficult world for librarians... I would have thought it to be the other way around. It was interesting to read about how librarians are trying to find solutions by creating web-based programs or functions, and seeing how these work with their current systems.

It was interesting to learn more about google and how (and why) it works. Besides being impressed over-all with everything that went into Google, I am also always impressed with companies that are dedicated to implementing procedures that keep their employees happy. If more companies would put a little bit of time and effort into that, perhaps they wouldn't suffer from high employee turn-over. What an amazing 'project' google was... it's incredible how much we each rely on google, and they always seem to have the answer we are looking for.

My question is regarding the phone system, "circuit-switched" network. We were told it assumes that less than 10% of lines are in use at once. That seems like a very low percentage. Why does it have to be that low? And do we have to reach 100% usage before getting the "circuits busy" message? Or do we hear that message when we get to a certain percentage?

Week 6 Readings
Local Area Network: http://en.wikipedia.org/wiki/Local_Area_Network
One thing I love about these readings is that I always learn something. It had never occurred to me before that Wi-Fi is a LAN, but of course that makes so much sense now!
Computer network: http://en.wikipedia.org/wiki/Computer_network
I have a PAN! (Personal Area Network)... but what I wish I had was a WPAN! I must say, though, there are many more types of networks than I ever realized. This article gave a nice overview of the various terms and their definitions and relations to each other.
Common types of computer networks: http://www.youtube.com/watch?v=1dpgqDdfUjQ
One thing he said is that we often use acronyms without knowing their meaning--so true! Besides that, though, he basically gave a brief overview of what we read in wikipedia. However, it is really neat that people can post these video clips where anyone can watch them. Anything that improves upon the ways we can gain knowledge is great, and posting such videos is definitely a beneficial thing to those who would like to learn.
Coyle, K. (2005). Management of RFID in libraries. Journal of Academic Librarianship, 31(5), 486-489.
When I first began reading this article, I wasn't sure what they were saying... but when I re-read it, I realized how cool these radio frequency tags are:
"The RFID tag does not have to be visible to be read; instead, it can be read even when it is embedded in an item, such as in the cardboard cover of a book or the packaging of a product."
Imagine the changes this brings into the library field! It seems that it could be very time-saving and helpful for librarians to utilize, and perhaps save money as well. Although it still has some concerns, it seems that they could be worked out and this would be a step up from libraries' current barcodes, etc. One thing I felt the article lacked is that it referred to the ALA's statement on RFID in libraries, but didn't say what their statement was, so the reader would have to research that themselves.

When we discussed Basic Audio Coding during the lecture, I was wondering about speech. We were told that the standard telephone channel has 8-bit samples; is that the same regardless of whether it is a land line or a cell phone? If there is a difference, what causes it?
