Cables

samxd

I learned that for like devices you would need to use a crossover cable, and for devices that are different you need to use a straight-through cable.

My question is, the labtop i have now connecting to my router which is connected to my cable modem is using a cross over cable, from what ive learned it should be a straight through cable because a router and a labtop are different devices. Can anyone help me with this question?

My last question is, for the roll over cables, are they only used when you want to connect your labtop to the console port on a switch or are they used for other thigns as well..

thanks

Correct. devices which send on the same pins use cross over to connect otherwise use a straight through

no, pc's and routers use the same pins to send and recieve data - 1,2 to send 3,6 to recieve therefore they use a cross over to connect to one another.

bridges and switches send on different pins to pc's,routers etc (1,2 to recieve and 3,6 to send) hence the reason you use a straight through cable from a pc to switch.
