[K12OSN] networking wisdom needed

[Peter Hartmann]

Hey Folks,
I'm looking into an older model Cisco switch for our backbone.  It's
the Catalyst 2948G-GE-TX.  The specs say, "the 48 10/100/1000BASE-T
ports [can] share 12Gbps of capacity (or 6Gbps full-duplex) into the
switching fabric. " How many terminals could that support max? 
Granted I don't think the whole school needs to play Tux Type
simultaneously.

Thank you,
Peter
