Question from a network hardware newbie

I’m implementing a network for 30 users without a lot of traffic and where the distance betwen the users and the servers doens?t exceed 100 meters (tipical UTP max distance). Would a Hub be enough for regulating traffic or should I go with a switch?If so do switches need to be configured like routers or do they create their “routing” tables automaticaly in memory has the books say they do? Security is not an issue here so no need to further segment the network.

Thanks in advance
