1, Wiki explains the concept of local are network (LAN), which is commonly used in home, office and some group of buildings. LAN was created by university network.
This article is concise and easy to understand.


2, Wiki: computer network
This is a good reading. It is very comprehensive.
Network classification: connection method, scale, network architecture and network topology.
Types of network: LAN, PAN, CAN, WAN,MAN,GAN, VPN ...
Hardware components: network interface cards, repeaters, hubs, bridges, switches and hubs

I have a question:
I found that we have many readings in Wikipedia. We also know that wikipedia allows anybody to publish and edit the concepts. In other words, the editors in wikipedia can be anybody. Is the knowledge on wiki true and authoritative? Why we rely on wiki to learn knowledge?



3, The video on youtube talks about the common types of computer net works. There are personal networks, Local networks and world wide networks. Though the man do not mention the many details about three types of networks. But I do like this video when I am tired of reading numerous papers. This is a interesting way for us to get knowledge.

Management of FRID in libraries
The technology of FRID is more advanced than Barcodes. The author analyzes the pros and cons of FRID in libraries. In my opinion, it may be a little harder for libraries who lack financial aid to realize the total change into FRID, sine using FRID in libraries will take libraries a lot of money. And FRID is not perfect.
