Local Area Networks - Wikipedia
LANs developed as computers got smaller and they were able to have more than one serving one function (multiple people/computers in an office working towards one goal). LANs are a type of computer network.
Computer Network - WIkipedia
Computer Networks are the basis of all that we know about online communication. These networks can be global or local (like LANs). They can be open or closed, private or public. They always require hardware for a computer to access the networks. They consist of nodal relationships that have their own specific characteristics.

Management of RFID in Libraries
RFIDs are small devices that go on objects to track them. The check-out possibilities (and payment abilities) is very interesting and would free up the time of librarians who are stuck behind the desk checking books in and out. It seems like it would be a small problem that not all object in a library (CDs, DVDs, thin journals and children's books, etc.) can be equipped with the technology. Until RFIDs can go on all the libraries' belongings, it probably won't functionally change the library circulation system. However, only being on books does save time and energy.

The RFID chips would certainly make life easier on librarians and would free up a lot of time. I don't think that libraries should use them until the technology is more advanced. As stated in the article, bubble gum wrappers can block the signal and the libraries will never know that a book was checked out and will never know it is missing or stolen. When the error is finally discovered it could be too late and the book is long gone. Until the publishers, stores, and libraries all decide to implant the chips and refine the technology, I think libraries will be better off with the current check out system.
ReplyDeleteI think RFID is a good system that librarians could use to save time and money. I learned a lot about RFID when I was at the business school. According to the website http://library.gaorfid.com/, RFID can solve many problems:
ReplyDelete1.Faster scanning of the data stored on the RFID tag,
2.Simple and easy way for patrons to self-checking for material loans and returns,
3.Superior detection rates,
4.Significantly reduce the number of false alarms at the exit sensors (up to 75% less)
5.High speed inventory - reducing time to by staff for 'shelf-reading' and other inventory activities,
6.Automated return of materials that speeds up sorting of materials and re-shelving for the next patron to access and
7.A longer lifecycle than a barcode.
It sounds good, but I am not sure if it really would free up people's time behind the desks -- if it works like the self-checkout in supermarkets, you will still need someone who helps people with the self-checkout system...
