actually, i have doubt about the broadband. many books say that the max download rate of ADSL is 9Mbps and that of cable modem is 36Mbps. so how to operate 100/1000 Ethernet? the network speed provided by ISP seems very small. i am wondering about that.
if the school network is needed to design, ADSL and Cable Modem, which one is better? how many fixed IP is needed? can only 1 fixed IP operate the school or normal company?
