NT kernel

Field:
Windows > NT kernel

The basis part of OS which is loaded onto Windows NT/2000/XP of the Microsoft corporation (the kernel) the popular name. Windows because development starts for enterprise server as OS, has strongly emphasized the guaranty of stability unlike generally known “9x kernel” to that.
The NT kernel is drawn up with 32 bit base completely, besides the fact that it has the address space where each one becomes independent, the address space of the respective independence and allotting the hypothetical machine can do to also 16 bit application 32 bit application, (also it is possible) to make share for compatibility maintenance.
In addition, as for kernel itself it has the address space separately from this individually. Because of this, whichever application crashing and freezing and it does not have an influence on the kernel completely.

numbered
Reading: Nun bird
Field:
Network technology > network control > numbered
Communication service > broadband > numbered
|
| The connected system which allots IP address to the WAN side port of the rooter which is connected to other network, handles the connection between 2 rooters as one network. The rooter which is used with numbered on side and WAN side, one at a time means that has the IP address 2 of total. When also the other computer participates in the network where 2 rooters participate, unless is allocated to the computer with respect to network, it becomes not be able to decide the destination of the packet which is transmitted from the rooter. Because of this, with the environment where the computer and the rooter 3 or more are connected to the network of WAN side, the use with numbered becomes necessary. |
