When a function call occurs in a program, the computer does the following: First, the parameters are pressed into the stack;The contents of the Save instruction Register (IP) are returned address (RET); The third is the base address that is sent to the stack(FP), then copy the current stack pointer (SP) to the FP as the new base address, and finally the localAmount of space, the SP minus the appropriate value. Take the following procedure as an example:
Some knowledge about storageAccording to the different transmission protocols, the network card can be divided into three kinds, one is the Ethernet card, the second is the FC network card, the third is the iSCSI network card.
Ethernet Card: The Scientific name Ethernet Adapter, the transmission protocol for the IP protocol, generally via fiber optic cable or twisted pair with Ethernet switch connection. The interface types are divided into optical and electrical ports. Optical ports ar
, 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
The maximum rate of Ethernet switch stack is faster, Which is multiple times faster than the port rate of the switch. Not all switches support Ethernet switch stack, when the number of ports that a single switch can provide is insufficient to meet the requirements of the network computer, more than two switches must provide the corresponding number of ports, which also involves the connection between switches. Basically, there are two ways to connect a vswitch: Ethernet switch stack and cascade.

View the 25G, 50G, and G technologies in the data center
Enterprises and cloud-level network data centers have a variety of "G". It is time to figure out their performance.
The rise of cloud computing and the expansion of data centers have promoted the latest Ethernet Speed upgrade, while cloud-based big data has also increased the workload of operators. To meet this demand, the data center expands by adding bandwidth capabilities parallel to the existing infrastructure. This trend is evidence
