The Straight and cross Cable are used for communication .And Roll-over cable used for configuration.
We use straight cable for communication between two different devices and Also for internet access on Device.
These three of cable are fixed on RJ45 ,

We Use Two Standard For Cabling:
1. 568A Standard
Consist order:-
White Green
Green
White Orange
Blue
White Blue
Orange
White Brown
Brown

2. 568B Standard
Consist order:-

White Orange
Orange
White Green
Blue
White Blue
Green
White Brown
Brown

“When 568A Cabling On Both end of cable then this cable is Straight cable”

“When 568A Cabling On one end and 568B on second end of cable then this cable is Cross cable”

“When 568A Cabling On Both end but on second end it is opposite means A865 cable then this cable is Straight cable (on One end 12345678 on second end 87654321 )”
Requirement
1. TP.
2. Connector (RJ45).
3. Clumping Tool.
