4) https://johnchihau.blogspot.com/2026/04/blog-post_28.html?m=1 . <--- It's about "Multiplexer".

. 

Me: Ok.

John : Now, we see the Pic above. PA refer to Physical address.  

Me: Ok.

John: Do you see a multiplexer ? 

Me: Yes, 

John : The modulator return a signal of 010101 (a Physical address selector) and [ 1 ](1 bit data input) to <<<the multiplexer>>>.  

Me: The Physical address of the receiver-machine enter the selector of the multiplexer.  And, 1 bit data enter the data input of the multiplexer. 

John : Yes, each Physical address has 2 access.  Access 1 link to the Gate of the modulator.  Access 2 link to the Output of the (modulator and the multiplexer).

Me: Correct.  However,  here's a problem.  If each "Single" bit sent must pass through the Cache,  the speed is very slow. 

John : Yes, the speed is very slow.  To solve the problem,  We use Line priority. 

Me: What is line Priority ?

John : Take a look. https://wodewangzhishime.blogspot.com/2021/11/httpswodewangzhishime_83.html?m=1 . It's line priority.
