What is SWITCH?
SWITCH is an acronym for the Southeastern Wisconsin Information Technology Exchange, a consortium of eight college and research libraries in the Milwaukee area of which the Stritch Library is a member. More detailed information can be found on the SWITCH web site. What it means for library users is that you get resources from the other seven libraries quickly and easily.
Switch is a kind of network device which is based upon MAC identification and can fulfill the task of transferring packets with encapsulation. A Switch may learn MAC address and save it to inner address list, transferring data frame from source address to destination address through the switching path created temporarily between sender and receiver. Switch and Hub both follow IEEE802.3 or IEEE802.3u standard and use CSMA/CD technique to access network.
