10/15 Reading Notes: Computer Networks, Wireless Networks

Common types of computer networks

This video brings to mind our class’s earlier discussion about about YouTube videos as learning tools. While the video does a good job of succinctly explaining types of computer networks, visually speaking it is pretty dull. The audio is useful but I’m not sure what the visual element added to the information being presented.

Local Area Network

One of the most surprising things I’ve learned this semester is how involved Xerox has been in technological innovation. I had no idea they were involved in the development of Ethernet.

I would have been interested in a more in-depth discussion of wireless LAN, since it seems like that is the direction most institutions are going.

Computer Network

This article makes clear the cost cutting and efficiency benefits of a well-organized computer network. Easier communication, shared hardware and software, and information and data accessibility are all important when an institution is trying to get the most use out of their technologies without killing the budget.

I also like the discussion of wired vs. wireless technologies, which does a good job of explaining some basic ideas I had heard before but didn’t understand (like coaxial cable). Same goes for the different kinds of networks – I’d heard of intranets and extranets before, but now I know what those terms actually mean.

“Management of RFID in Libraries” by Karen Coyle

RFID is an exciting technology, but it seems unlikely that all libraries will adopt it any time soon. Though it might be cheaper in the long run, I think the initial costs are a huge deterrent with budgets being what they are now. Improving the availability of electronic resources seems to be a higher priority. Maybe a few high profile libraries using RFID technology would make it easier for others to request additional funding; or maybe this is already happening and the economy is just too bad for there to be any effect? Either way, it does seem inevitable that libraries will adopt RFID eventually. Maybe by then, it will be a little more affordable.
