Cable Length Question

helios

Hey everyone... long time visiter, first time poster... I think..

anyway, I've been studying for my Net+ (writing on Apr. 20)

My Question is...

For a 10baseT network, the length is 100m. Is this cable length or segment length?

On a segment, could you have 4 computer that are 100m apart?

Thx!

yeah, if you're running a 100m cable to the hub/switch, which has a 100m cable running to another box, they'll communicate. The cable length is limited to 100m due to attenuation.

Now keep in mind that within a collision domain, there's the 5-4-3 rule, which gives you 5 segments total joined by 4 repeaters with no more than 3 populated segments (ie, have nodes on them). This is due to propogation delay.

Of course, when you throw switches into the mix and break up collision domains, things change a bit hehe
