Local Area Network
LAN ,WAN, and Ethernet are terms that I have used over the years to describe different cords that hook my computer up to one device or another. Now learning the actual definitions, I see why. I found it helpful in this article to click on some of the links for further explanation.
Computer Network
This article presented me with a lot of questions: My boys and I are connected with Ethernet cables to the same router and the router is connected to the Internet by Cable. We are able to use the same roadrunner account etc., but cannot access each others documents, etc. (at least to my knowledge) is our connection considered a LAN? Is the Bb Academic Suite a Hub? Are we involved in a GAN if satellite Internet access is used?
YouTube Video This video was helpful to firm up a couple of the ideas I had read in the previous article. It answered one unasked question when making the wireless router comment. I watched a few of the additional YouTube videos presented on the same page and they were interesting and helpful also.
Management of RFID in libraries. Journal of Academic Librarianship
My son's Scientific America Magazine just had an article about the use of RFID in Libraries and their communities. It theorized that eventually we will have one key fob or whatever with a RFID installed that would act as a library card, bus pass, school ID, etc. This article addressed the cost of the system to the Library. My question was the cost to the consumer! In 2006 I lost my car key that has an RFID chip in it. When I went to the shop to see about getting it replaced, it was going to coast over $250.00. Needless to say we just used the spare key until the other showed up. What will it cost to replace a lost library card? How many library cards have I lost in my life? Only two over 41 years. It cost me a total of $14.00 to replace these cards. I'm afraid that if RFID cards were introduced and my card was lost I simply could not afford to use the library.

I never thought of the cost of the RFID chips. Now that you mention it, I remember my dad telling me I couldn't get him a spare for my Jeep because the key would cost a few hundred dollars. I couldn't believe it. You have to wonder what type of costs would a library have to endure to switch everything over from a barcode system to a RFID system.
We have a similar network at home and we call it a LAN. I was also wondering as I read the article if that is a correct classification or just what we call it because when we link up to be a happy (and geeky) family to play Neverwinter Nights we use the LAN connection option. We do share documents. My tech support (husband) set up shared folders on each of our computers so we put the documents in the folder on one computer and can access them through the others. Very handy and very 'doable'.
