Single PC to PC Lan or Laptop to Laptop LAN Wiring

In order to communicate among pc to pc  or Laptop to pc or pc to laptop through lan or other network two things must be needed to make this happen. One is the data transmission and another is the data reception.  In single PC to PC lan or laptop to laptop lan network no Hub or Switch is needed.

So we can use either 10base-T or 100base-TX standard for this. For 10base-T normal speed is 10Mbps. And with 100base-TX you can get speed up to 100Mbps. But 10base-T cat-3 cable can be used but in 100base-T cat-5 cable is recommended.  But it is always recommended to use 100base-TX standard for this single pc to pc or laptop to laptop or pc to laptop lan.

Both 10base-T and 100base-TX use one 2 pairs of cable from 4 pairs of UTP cable. They follow 568A and 568B wiring standards. To know more about this please read the previous article.

So the main thing is, we just have to make a cross cable connection for  this single pc to pc or laptop to laptop LAN. For making cross cable connection, the easiest way for 10base-T and 10base-TX is on the one end of the cable connect with RJ45 connector using 568A wiring standard and on the other end connect with RJ45 connector using 568B wiring standard.
