execute customer commands or request, and only the main board knows how to implement Customer commands. Therefore, we should abstract the main board first, describe it with an object.First, define the interface of the motherboard. At least the motherboard will have a method that can be turned on. The sample code is as follows: /*** Main board interface*/Public interface mainboardapi {/*** The main board has the ability to boot.*/Public void open ();} If the interface is defined,

That is, the 2 TB of empty division multiplexing is irrelevant, and when one of the terabytes fails, another successfully received TB does not need to be re-transmitted, and a successful TB harqprocess can be used for the next new pass.
