How to connect two pc to be transfer data between them

If you wish to connect two PCs to each other,
they both need to have network cards
installed. You’ll also need what is called a
crossover cable. Now, first make sure File and
Printer Sharing is enabled: open Network
Connections in the Control Panel, right-click on
Local Area Connection, and select Properties. In
the General tab, look for “File and Printer Sharing
for Microsoft Networks” and make sure the
checkbox next to it is selected. (If it isn’t in the
list, go to Install > Services > Add and choose this
service to add it.) Now return to the General tab,
select “Internet Protocol (TCP/IP)” and click on
Properties. Enter an IP address such as
“192.168.1.10” and a Subnet Mask of 255.255.255.0
for one computer, and the IP address
“192.168.1.11” and the same Subnet Mask for the
other. Now, for a particular folder that is to be
shared, right-click on it and click on “Sharing and
Security”. Enter the share name of the folder and
click OK. Connect the two computers using the
crossover cable. You should now be able to access
the contents of the shared folders on one
computer from the other.
