John: This article ( https://wodewangzhishime.blogspot.com/2022/03/httpswodewangzhishime_7.html ) mention about the direction of current flow of RJ45. Me: OK. John: Now, we look at the 3rd picture. The direction of current flow of the secondary coil must be opposite to the direction of the current flow of the primary coil. Me: Correct. If we don't do that, the current flow of the primary coil will stop. . John: Now, I change the story a little. Me: OK. . John: The direction of the current flow of the secondary is occassionally opposite to the direction of the current flow of the primary coil. Me: Occassionally? John: Yes,. Me: Then, a carrier wave will be formed. John: Now, we look at the 2nd picture. Me: OK. . If the direction of the current flow the Port B is occassionally same as the direction of the curr...

sequential (97) Common network and switch network

John : Take a look.   https://kamchihau.blogspot.com/2022/09/different-frequency.html?m=1  . It's about a 3rd party's common network.  Now, we talk about network switching.  Me: Ok.  John : SIM Card A and B are in different network.  In order to communicate with each other,  SIM card A switch switch himself and the Cache of his physical address to France's network temporarily.  Me: In this case,  SIM card A is the master and SIM Card B is the slave.  John : Yes,  SIM card A pay the Communication Cost.

John: Before we start, you may read this article ( https://wodewangzhishime.blogspot.com/2023/08/2001-4-airplanes-were-hacked.html ). . Me: OK. John: If the direction of current flow of port B is "occassionally" same as that of port A, there will be carrier wave formed. . Me: OK. John: Look at the picture above. Those carrier wave will affect the data input of Port A. Me: Those carrier wave also affect the Clock line. Consequently, register R1, 2, 3 become unstable.
