So, the fiber-optic network card is the name in the end is the fiber port HBA card?
In fact, the fiber-optic network card that you often refer to is the HBA card in the Fibre Channel networks.
Because of the different transmission protocol, the network card can be divided into three kinds, one is Ethernet cards, the other is FC network card, the third is iSCSI network card.

, what's more, the installer simply overwrites the system files of the new and old versions (many games and irresponsible applications do this ).What are the consequences of overwriting system files? It is hard to say that if you are lucky enough, you may not have any problems. But in most cases, it is to make your system unstable or crash at some specific time. In this case, Microsoft engineers use the DLL Hell-the Windows system uses the Dynamic Link Library (Dynamic Link Library) to share all

is an integer representing a specific signal. We ignore it temporarily.
The previously assumed function body defines the sigfunc function. Therefore, the declaration of the sigfunc function can be as follows:
Void sigfunc (INT );
Now, if we want to declare a pointer variable pointing to the sigfunc function, we may name it SFP. Therefore, SFP points to the sigfunc function. *

Installation programs that are not part of the operating system can overwrite shared system files, even when it is incorrect to do so. This has been a common problem in the history of the Microsoft? Windows? Operating systems. overwriting shared system files with older versions or modified versions of the file can result in unpredictable system performance that ranges from application errors to operating system crashes.
