The difference between a fibre optic network card and an HBA card

, thus forming a network of hardware devices. 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. • Ethernet Card: Scientific name Ethernet Adapter, transport protocol fo

Go deep into Windows ME system files

, 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

If anyone finds any vulnerabilities, please let me know. Below is some of my implementation code: Set_session () is called during login. Start_session () is called before each page. Kill_se

C/C ++ function pointer Declaration

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. *

Introduction to four types of Optical Fiber Jumpers

Optical fiber jumper (also known as optical fiber connector) is a Connector Plug installed on both ends of the optical fiber, used to achieve optical link activity connection; one end is equipped with a plug is called pigtails. Optical fiber jumper (also known as optical fiber connector), that is, the optical fiber connectors connected to optical modules, also have many types, and they cannot be used with each other.
