can you put a switch hub on a prolink hurricane 9200 modem?

i want both of my computers at home to have internet connection. does my modem can do it by just putting an 8 port switch hub? they say this model is a built-in router?? is that true? i read its specifications and it says there that it supports functions such as DHCP Server but i don’t know what that means. and how will i set it up so that both will have internet connection? how will i configure them?
