Week 5 Notes

Wikipedia: Local Area Network

Local Area Networks allow computers in a small, contained space to connect to each other. These networks allow computers to connect to the Internet. How do Ethernet cables work? What is ARCNET?

What is the benefit of using a LAN rather than a WAN?

I've heard my gaming friends talk about LAN parties. What are they doing, and how does that work?

What sort of security risks are involved in connecting to a LAN? How do prevent hacking?


Wikipedia: Computer Network

How would life be different if we different have computer networks? I imagine life would be completely different. Even in the past few years, we have made tremendous progress with technology. Studies show that we're using technology and consuming media on technological devices more often than ever before. Without the invention of computer networks, we would be more sociable and personable. We would spend less time in front of screens and more time interacting with families and friends. Of course, it would be harder to stay in touch with people spread out across the globe, but it would also mean that people would have smaller, tighter, more local groups of friends.

How are MAC addresses assigned? How do they ensure there will be no repeats? What happens to a MAC address once the device no longer works? Can the numbers be reused?


Management of RFID in Libraries

How expensive would it be to implement RFID in libraries?
How receptive would the public be to the change from barcode to RFID?

Coyle talks about ways to bypass the RFID system. Do libraries really need to be concerned with people intentionally stealing books? Sure, libraries don't have a lot of money to spend and a limited number of materials. However, libraries are based on a lending principle that requires people to be honest. There will always be people who return books late or misplace a book. But do enough people intentionally steal books to make thwarting security a huge issue?

Coyle also talks about the ROI for librarians. However, the procedures that she claims will save time and money actually cost money. Installing automated checkout booths costs money and a lot of it. It also involves space. Small libraries won't have the space. What about jobs, too? If we help usher in automated services, are we willingly eliminating our own jobs? I'd like to have and keep a job in libraries, no matter how technologically developed we get.
