how to connect two computer using a cross-over cabel? in details?

Answer 1

You plug in the cable between the two computers, then you need to go to 'Control Panel | Network connections' then right click on Local Area Network and then Properties.

Click Internet Protocol (TCP/IP) and then Properties. Then you click "Use the following IP address."

and put something like:

IP Address: 192.168.0.100
Subnet mask: 255.255.255.0

and for the second computer, just use any other IP address with the same start (like 192.168.0.101)

Then you can use the different services available between the computers...whatever they are. (FTP, file sharing, etc..)

Answer 2

First: a regular network cable will not work. You need what's called a "reversing" or "cross-over" network cable. The problem is that a regular cable will connect the transmitter of computer A to the transmitter of computer B, and the reciever to the receiver. What you want is the "reverse" - you want the transmitter of one computer connected to the reciever of another. (Hubs, routers and the like know to listen to the transmitter, and send to the receiver - so "normal" cables work just great when you're connecting to those.)

Second: you may need to install an additional network protocol. If all you're doing is connecting two computers, you may need to install either the IPX or NetBEUI protocols. It's more complicated than is neccessary to get into here, but these protocols allow computers to identify themselves, rather than relying on some other device to assign them an address. In this case things that rely on TCP/IP will not work. However, if you use Internet Connection Sharing on one of the computers to share a connection, then TCP/IP, and all the tools that rely on it, will work and no additional procotols will be required.
