Telecommunitacion

A channel is a division in a transmission medium so that it can be used to send multiple streams of information. For example, a radio station may broadcast at 96.1 MHz while another radio station may broadcast at 94.5 MHz. In this case, the medium has been divided by frequency and each channel has received a separate frequency to broadcast on.

Now the question, is the channel or the frequency or none of them created by the router???

I guess the router creates the frequency because it depends on the router's capcity how much signals it can send per second. If I am wrong, let me know. So if the flow of information is, let's say (IMGAINARY), a 100 signals per second, and the router can send only 77 than only 77 will be transmitted and the other 23 will not. I think so...

Wait, but doesn't the router simply redirect information to either a network or another router?
I thought the router is the one that ensures the information goes where it has to go, or where it does NOT have to go (avoiding information overload in networks as we talked about last class).

But is it creating frequency?

well montag...if the router creates the network...whats the difference betweem the network and the frequency???

No, I don't think the router "creates" the network. It manages what goes where within the network / what goes to which network.

Unfortunately, doesn't mention frequency / channel, but still useful.

This video has a little something on switches and routers:

Ok guys, what I would say is that a router works as a radio transmitor - basicly it creates a wave with a specific frequency. The question though is - is the wave created by the router the same type of wave as the one created by the radio? I mean - there are different types of waves (radio for example does not use the same waves as the sound or light does), therefore there is a question if all routers don't create a different type of wave, and than every single router creates a specific frequency (the same as radio is using electromagnetic wave but each radio has its own frequency) - that's just a guess though

Maybe we have to wait for Mr Torresk to say smth (: But I think it is this ...
