I plan on hosting a internet game (tac-ops)
and i was wondering if anyone out there would know what i should have for internet (bandwith speed)
also ...
would it be effecient to connect the modem to a network switcher or should i just connect it to a router
Dsl would be fine for hosting a tac-ops game, I assume you mean a dsl modem since dsl is in the title of the post. I've hosted counter-strike games with dsl before, and tac-ops isn't any more resource hungry.
As to the second question, I don't understand why you wouldn't just connect the dsl modem to your PC. There's no need to connect the modem to a switch or a router and then to your PC if it's got nothing to do with a LAN, unless I misunderstand something... ???
You could connect the DSL modem to a hardware Firewall/Router for added security, though it may make hosting a game server off it a little more complex in configuration and all. Thats mostly an opinionated decision on your part.
