This reading really developed my understanding of computer network coverage systems. In my mind, LAN just silently exists in the walls of buildings, throughout cities and in the steam tunnels at MSU. HA!
The wiki's description of standard evolution is surprising in its assertion that 1983 was the "year of LAN" It's difficult to believe that networks were being developed so early in personal computer popularity terms. I was also under the impression that LANs were generally separated from one another purposefully- the discussion of largely linked LANs (say that three times fast) elaborated on the use of redundant links as a means of preventing loops and enhancing the functionality of "difficult traffic" types.

I enjoyed the wiki's classification of computer networks by distinct characteristic.
Particularly interesting is the discussion of coaxial cables mode of reducing inference and distortion through the inclusion of layered insulation. The wikis network type classification is also found highly interesting. College campuses, airports and office buildings are interesting examples of Local Area Networks

Coyle, K. (2005). Management of RFID in libraries. Journal of Academic Librarianship, 31(5), 486-489.
Great article! Earlier in the semester Dr. He had mentioned RFID technology is class, since than I had been waiting in anticipation to hear where and how this technology would impact libraries. The uses for RFID (inventory pallets, dvds, drug labeling, pet IDs) are expansive and interesting. Coyle's discussion of the pros and cons of integrating RFID's into a library setting include attention to fiscal considerations, the possible structural and institutional gains, and the security opportunities. Her discussion of the trends in RFID technology developments draw attention to the need for libraries to decide for themselves how they will approach the new technology, if at all. Coyle makes very clear the likelihood that RFID will become a vital asset to libraries.

I agree about the Coyle article. Doing library inventory with RFID chips would be so helpful. Not having to take material off of shelves would avoid mistakes and would be way less time consuming. I think it is a good direction to be heading in library science.
ReplyDeleteI too was surprised that the year of the LAN was in 1983 - it is hard to believe networks have been around that long. I also enjoyed the Wikipedia articles and the descriptions and classifications of the different networks - it was very easy to understand and envision. You couldn't get the video to work? You didn't really miss much - it was only about a minute long and basically the man just broke down the definitions of LAN, WAN, etc. in really simple terms.
