Ok I have a customer who needs a network installed in a building there turning into a private school. The problem is it used to be a tasty cake factory. It's walls are to thick to lay wiring inside and the florrs/ceiling are reinforces stell and concrete. So I called up Cisco and they recommended doing a w ireless acess point on the top floor to cover the floors and then a router in the basement. okay so I need my math checked. the height of the each floor is 20ft the length and with are 200 and 150 feet which means were talking a calculation of 200ft*150ft*20*4= 2,400,000 which would be 2,400,000 cubic feet. Am I correct in the math and concept?
Ok I'm studying for my network+ exam the only thing I'm seem to be a little unsure on is calculating users and hosts using the subnet masks. Ok so here is the thing you calculate how many subnets by 2n when equals the number of bits so in other wards 2*8 power 256 the concept is the same for hosts except you subtract two you get 254 that gives you your default subnet mask of 255.255.255 but lets say my network needs this is the class c standard. So all I need to do to increase client capacity is adjust my gateway mask address. In other wards if I adjusted 255.255.250 that would give me an extra 38 hosts? And an extra 40 subnets?
