John : This article is about the "width" of data bus, e.g., 4 bits, 8 bits, 32 bits. https://wodewangzhishime.blogspot.com/2022/04/httpswodewangzhishime_23.html?m=1. You might have a look first. 

Me: Ok.

.

John : See the above 2nd Picture. All control bus, data bus and address bus are the branch of Clock line of RJ45.

.

Me: In another words,  if hacker hack the Clock line of RJ45,  hacker can hack the system bus (Control, address and data bus).

.

John : Yes, take a look. 

.

1) Address bus.

2) Data bus, e.g., parallel input output line, serial input line.

3) Control bus, 

e.g., 

interrupt status [ RJ45 clock line],

Subject [ Register A ],  

Object [ Register B ],

Left_Right_Shift status [ Right shift ],

Load_Shift_status [ shifting ].
