John: Before we start,  you might have a look. https://chihaukam.blogspot.com/2024/09/blog-post_2.html?m=1 .

Me: Ok.

John: See the 1st picture. The binding-network, e.g., IP or Telephone,  are seperate from the harddisk of Telecom. 

Me: How do they connect ?

John: By serial communication, e.g., Ethernet. 

.

John: R0 is a physical address which correspond to my "Cellular phone". 

Me: Ok.

John: When my mobile is switched on, I got a physical address from the binding-network. 

Me: Ok.

.

______

.

John : My SIM Card has a unique ID already. Based on this unique ID,  the binding-network will help me look for an available IP or available Telephone number from the harddisk of the telecom. I use "available IP" as an example.  

Me: Ok.

.

______

.

John: Now, you see the 2nd picture.  There's a series of Magnetic in the harddisk of the telecom.  And, there's a Magnetic "sensor" sweep from 1 to 8.

.

Note : In reality,  apart from Magnetics, there's is Optics which are used as "Permanent store". We only use Magnetics as an example.

.

Me: It's a bottle neck. Why? A magnetic "sensor" return to us a signal of either 1 or 0 bit by bit. Either have "magnetic field" or no "magnetic field. ".

.

__________

.

John : Yes, after sensing, we shift the Permanent storage (Magnetic) to the temporary storage (Cache).  

Me: In another words, the "temporary" datas will be placed on the cache of the harddisk of Telecom.  

.

John: Yes, Lastly,  we go through a series of, 

.

Int available_ip = select the top 1 line from cache_table of the harddisk of Telecom.

.

Update cache_table of the harddisk of the Telecom where line = Top 1 line.

.

Set Top 1 line Unavailable. 

.

Socket (available_Ip, Binding-network);

.

Clear available_ip.

.

Me: So many steps. 

.

John : Yes, on top of it,  between the harddisk of the telecom and the Binding-network,  it is a bit-by-bit Serial communication,  e.g., Ethernet.  As a result,  I need 10 seconds to obtain my IP.
