Im currently studying for the N+ but I has recently wondering about a few things with network ethernet wiring

As I understand 10/100/1000baseT networks have a max cable lenght of 100 meters between a switch/router and the computer, meaning after every 100 meters you need an access point to boost the signal.
What I was wondering where do patch panels fall into this, ie are they just an extension of the cable so you still need to plug into a switch/router to extend past 100 meters or do they also act as amplifers so to speak?

No - patch panels don't amplify the signal at all... they merely provide a point to join the wires from two cables together.

 

cool thx for the info

 

And the use of the term 'access point' is confusing - that term belongs to WiFi.

A hub or switch is what you need to extend the reach of a network.

Note that there is a limit to how many switches can be used like this.

Harry,

Could you expand on the last comment about the limitation of switches...

 

how many switchs/hubs can be used like this ?

 

This is a little hard to pin down because it depends on the quality of the switches, and the precise mode they work in. The controlling parameter is the end-to-end delay in a collision domain - if this is too large then the network will misbehave.

There is a fair amount of slack in real-life products, which make things even harder.
