It says there are different types of ethernet cables:
-straight-through cable
-crossover cable
-rolled cable
I looked online and the 3 cables look the same from outside.
The book goes on and says each type of cable is used to connect two different equipment. And, crossover cable is the one we use to connect a host and a router. My question is when I went to buy an ethernet cable (RJ-45) at best buy (to connect between the router and my machine), I didn't have to ask the workers whether it's crossover or not. I plugged in the cable and it has been working fine.
So, right now I wonder if I happen to be lucky to get the right cable or is there any good explanation behind it. Also, is the cable I have really is a crossover cable?
Say, if I happen to have a rolled or straight-through cable, would it have worked if I were to use it to connect between a router and my machine?
So confused.
Thanks in advance.

RayRay&Kiran,
Thanks for the answer.
I still wanna know if I was just lucky or something at best buy that time to get the right cable. Or are all cables at those stores are crossover?

Ok, now I got it. It's actually straight-through I'm using. Thank you all for replying. How nice.
Back to my other question, so when you go to best buy, you have to look to see what type it is or what???

When you buy a cable its usually Straight-through and it was just right for the task at hand, connecting your router to your machine. But if it were from your switch and say a hub, it wouldn't have worked.
Google the different cable pinouts and your will get what you want and how to do it.

Well with most routers that you buy from the store for a home network comes with a straight through cable. Which is what you need from a router. Most of the time when you want to use a crossover cable it is to connect a pc to pc. The straight through would be used from router, hub or switch to pc.

First, You use never crossover cable to connect router to computer; you use straight-through cable. I use crossover cable to connect two Cisco routers, or connect Cisco switches. You can use crossover cable to two computers without a hub. I use straight-through or rolled cables to connect from patch panel to switches. If you have LAN cable tester, then find out what cable pin-outs are. On straight-through cable, the mapping will be 1-1, 2-2, 3-3, etc. On crossover cable, then the two pairs swapped when you tested it.
On your third question, the packages are printed on them what kind they are since you can't tell without breaking opening the package.

Most routers/switches/hub these days auto-sense MDI/MDIX so both a straight through cable and a cross-over cable will work.
which managed to confuse the hell out of me the first time I came across it, but go with the flow, whatever etc etc. If it works don't worry about it.
As the previous answer says if you look at the plugs side by side you can usually see the difference, try it in a store with a straight thru cable and a x-over cable.

Remove the jacks, hold them the same way and compare the colors of the wires going to the 8 gold pins. If they are the same, you do NOT have a crossover cable. If 1,2 and 3,6, are reversed, you have a crossover cable.
Your setup didn't require a crossover cable, anyway.
If you had gotten a crossover cable, it would not have worked.

Most likely you have a straight-through cable. Crossover cables aren't needed if your router supports auto-MDI/MDIX. The auto-MDI/MDIX will allow a straight through or crossover cable to work when a crossover cable would have been required without the auto-MDI/MDIX.

Make certain all of the proper lighting fixtures are lit up at the entrance of the modem, .....Unplug all of the wires to the modem and unplug the vigour, close down the laptop for approximately two mins then plug within the vigour to the modem and plug in all wires receive the cable, flip laptop on and allow all of it load then plug within the Cable connection to the modem. Should paintings after a couple of seconds
