Hi,
I want to configure a network. I want to connect different types of devices. But I don’t know what kind of connection (crossover or straight) is used for different devices. Such as computer to hub, computer to switch, computer to router, computer to computer etc.
Which shall I use cross over connection and straight connection?
Straight means, that the cable's wire runs straight through, while cross over means that the transmission wires are crossed over, to the reception end and the reception wires are crossed over at the transmission end.
When you want to connect a computer for example computer to router / hub or modem, you must use the straight method. But if you want to connect a computer to another computer or what is called a peer to peer, you will use a cross over method.
I’ll give you a basic illustration to understand.
PC to Switch = Straight
Modem to Switch = Straight
PC to Modem = Straight
PC to PC = Cross Over
You use only cross over, when you are connecting two similar devices, like computer to computer.

Hello Limon,
These are the different connections of each device.
Computer to Computer uses 100 base-T Crossover cable;
Computer to Hub or Switch uses 100 base-T straight-through cable;
Computer to Switch uses 100 base-T straight-through cable;
Hub to Hub uses 100 base-T Crossover cable;
Switch to Switch 100 base-T Crossover cable;
Router to Router 100 base-T Crossover cable;
Switch to Router 100 base-T straight-through cable;
Router to Switch used 100 base-T straight-through cable;
When it comes to Computer to Router connection, some routers can automatically configure the connection or auto switch if used crossover connection.

Hi,
You can use both, straight – through and crossover cables. The straight – through cable if the connection is router to a hub or computer to a switch or may be your LAN port to a computer  or hub  and the straight can connect the pin on the same or opposite side. The crossover cables, can be used if the connection is computer to computer.
There are devices that have advanced circuits, like the router that can use both connections, like the crossover and straight through but the straight-through cables cannot connect unlike the device router or a computer.  However, both crossover and straight-through cables can work.
