Jeff Tyson, "How Internet Infrastructure Works"

This article explained some complicated information in simple terms, which made it easier for me to understand.

I learned that routers have two purposes: to make sure that information does not go where it's not needed, and to ensure that the information needed makes it to the intended destination.

I also learned that URL stands for Uniform Resource Locator, and that Domain Name Servers handle billions of requests daily and are essential to the Internet.

"Management of RFID in Libraries" Journal of Academic Librarianship, 2005

I find this article immensely interesting. It opened my eyes to the possibilities of RFID tag usage in libraries. Imagining being capable of eventually checking in an entire stack of books at once is astounding to me!

The library where I work have exit gates and we put a card in the pocket in the back of the book to signify an item has been checked out, which also prevents the alarm from sounding. While I suppose this is fairly typical library security, I had not thought of the tag in the pocket as an RFID before reading this article.

I guess it is possible that RFIDs will replace barcode technology, but I think the technology needed to adapt it to a library setting (an RFID that would work in a thin item, and last many years) is not yet in existence.

The most common network is the PAN (Personal Area Network) which usually includes at least one pc and a device such as a printer, usually found in homes.

LANs (Local Area Networks) are supposedly the second most common network, which can be found in offices, for instance.

The third most popular network is a WAN (Wide Area Network) which are larger than LANs in scale.

The fourth type of network are Campus Area Networks (CAN), which as the name implies, are a network encompassing a university.

MANs (Metropolitan Area Network) are networks that cover a city in geographical area.

Wiki Article on "Computer Network"

A computer network, as the name implies, is a group of computers, and devices, connected by communication channels that allow for communications among users and allows users to share resources.

Computer networks can be used to facilitate communications, to share hardware (such as a printer), to share files/data/information, and to share software.

Computer networks can be classified by the hardware or software technology used to connect the devices, as well as the scale (or size) of the network. There are a plethora of types of computer networks.

The basic hardware of a computer network contains: network interface cards, repeaters, hubs bridges, switches and routers.
