PCI is the abbreviation of Peripheral Component Interconnect (standard for connecting peripheral components). It is the most widely used interface in PCs, and is available in almost all motherboard products. PCI slots are also the most frequently

A Bridge device is a kernel-based L2 data exchange device that functions similar to a second-level switch in the real world. A tap device is a point-to-point network devic

Correct the error. NOVA: Added support for NFV. This is very important to the open NFV project, opnfv.org. NUMA seems to be a key optimization object. High-end servers, such as Xeon QPI, are all NUMA architectures. Libvirt needs to expose more interfaces to control the upper layer. Virt d

vendors, such as AMD's a85x/a75 and Intel's z87/b75 are the chipset codes. It is mainly responsible for controlling non-video card slots such as sound card, Sata device, and I/O interface. It almost determines all functions of the motherboard and is the most important chip in the motherboard. There are a lot of old materials on the Internet, such as the "chipset" entry under Baidu encyclopedia. It also says [it is a general term of "nanqiao" and "beiqiao ], in fact, the North Bridge has been i

alignment. So pay attention to byte sequence conversion. When the powercp processor reads int_ack, the host converts the read operation into a PCI bus to interrupt the response transaction. It is the configuration space of 64 bytes that the PCI device must support. The value range is 0x00-0x3f: Many PCI devices only support 64-byte configuration space. The differences between PCI and PCIe configuration spaces are as follows: PCI/PCI-X and

PCI Express, with four-port gigabit connections providing higher network bandwidth Using a four-port Gigabit server Nic on any server, especially on Intrusion Prevention servers, can demonstrate significant advantages. The four-port PCI Express (PCIe) server Nic can provide four network connections from a single server slot, so that other server slots can be retained for more applications. Multiple Gigabit ports can increase network bandwidth through

, we believe that all mechanical hard disk notebook should be upgraded to a solid-state drive, because it brings the ascension is too obvious. Note: Solid state hard disk currently has several specifications and interfaces, we need to select suitable for their own machine products, the following we explain in detail.

three types of length (80mm, 60mm, and 42mm ). Currently, all mainstream laptops are of the 2280 specification and are compatible with the 2242 specification. However, you still need to check the disassembly diagram or product description of your notebook on your own.In addition to the shape specifications, the M.2 hard drive also has two different channel versions. One is the PCIe channel, and the other is the SATA3 channel.The
