The concept of the local area network was very easy to understand. I use it everyday at home. The part I found most interesting was the history of networking. In the end, all the networks are interconnected creating a global communication infrastructure.

This article expanded on the previous article. I really liked the descriptions for the different types of networks. Each network serve a different group of consumers. However, all the networks interact through the internet.

The YouTube video was very informative. The terrestrial microwave information makes me consider how far we have come today. Things no longer have to be within line of sight to transmit. The amount of area that a network can cover grows every year.

This article has an important implication for libraries. I do see RFID possible replacing bar codes in the future. Currently, however, there are too many security risks with the system. Also, libraries would have to spend a lot of money transferring bar codes over to RFID. As we all know, libraries are currently do not have a lot of cash due to the economic situation. That is the main reason I do not believe RFID will be instituted into the main stream of libraries.

Yeah - I think that the RFID technology won't be used extensively until the cost of the technology comes down. I don't think the article quoted exactly how much it would cost. This site (http://www.barcoding.com/faq/rfid-tag-cost.shtml) says it could already cost as little as 50 cents per tag (and as much as $50 or $100).
