Crossover cabling is essential if you want to share files between your laptop and desktop (basically two computers). Its very cheap to prepare a crossover able. You just need two RJ45 jacks, CAT5e cable (length depends on your requirement) and one crimping tool. Apart from these one more important thing is there, that is color coding which I am going to tell you in this article.
The process of crimping is so simple that, if carefully followed, a newbie can also do this with no difficulty. Because this is a crossover connection (i.e. PC to PC connection, no hub or switch is required) it is a bit confusing than direct LAN cabling. But, once you understand the color coding, it will become the easiest job in the world. So, pay attention read carefully.
If you facing any difficulty to understand these color code or you have no idea about cable crimping then you can purchase any crossover cable from below mentioned amazon list.
