Networks at the U of M

COMP1260 > Computers and Networks

Introduction Networks at the U of M Network is a connection among objects for the purpose of communication. Computer networks is a connection of computers. The importance has been highly increased not only that most works rely on computers but also that many students has their own laptop. In fact, the University makes 'uofm-secure' be connected by students as well, since they realized 'uofm' wireless connection cannot handle many connections at the same time.

...by students wired is not supported 'uofm' is slow and hard to connect 'uofm-secure' is really secure because it kicks me off. </td> </tr> </table> Networks at the U of M The U of M has subscribed to AT&T Global Network Services. For local access network, U of M use both wired and wireless network. Wired network is implemented with RJ-45 cables common wires used on various places for networking. Every computers in laboratories, offices, and classes are using wired connection; however, there are limitation of this connection. Because U of M wants to prohibit someone who connects without permission, the wired connection is filtered by MAC address. Thus, to have wired connection at U of M, every computers need to provide MAC address before hand. On the other hand, there are RJ-45 cable ports for students in some computer laboratory. The places can be found on here, the web pages of Information Services and Technology (IST). Since these ports are providing to students, they do not need to provide MAC address; however, students need to bring their own RJ-45 cable. Wireless connection is opened to every one who has university accounts. There are two provided wireless connections - uofm and uofm-secure. In the old days, uofm was main wireless connection provided to students. Since uofm-secure has been become main wireless connection, uofm becomes temporary connection. Wired Network In general, there are two types of wired connections which are with MAC address and without MAC address. MAC address is an unique ID of a network device provided by manufacturer. IST gathers MAC addresses of individual computers in laboratories, offices, and classes in order to provide a network connection.
