, otherwise, will burn the power amplifier ). Digital audio interface:It is a standard format used to define the digital interface protocol between two digital audio devices. It is divided into domestic and professional formats: A. Household standards: S/pdif (Sony/Philips digital interface format), eiaj CP-340 IEC-958 coaxial or optical cable, is not balanced. The standard output level is 0.5vpp (transmitter load 75 Ω), the input and output impedance is 75 Ω (0.7-3 MHz bandwidth), commonly

The network adapter is connected to the network. Therefore, an interface must be provided to connect the network adapter to other computer network devices. Different network interfaces are applicable to different network types, at present, common interfaces include Ethernet RJ-45 interface, fine coaxial cable BNC interface, coarse coaxial electrical AuI interface, FDDI interface, ATM interface, etc. In addition, some NICs provide two or more types of

to the quality of the Crystal Oscillator when selecting.For example, the clock circuit of a network card uses a high-precision sko25 MHz crystal oscillator, which ensures accurate synchronization of data transmission and greatly reduces the possibility of packet loss.As close as possible to the main chip, the signal cabling length is greatly shortened, and the reliability is further increased. If the inferior crystal oscillator is used, this can reduce the cost of the NIC, but it is easy to cau

the electromagnetic field to the different levels of the connecting cable at the other end; one is to isolate the different levels between different network devices connected by the cable to prevent different voltages from transmitting damaged devices through the cable. In addition, data mercury can also play a certain role in lightning protection of equipment. Rj-45 and BNC connector: RJ-45 is a network interface with twisted pair as transmission

easy to cause data packet loss during transmission. ● Network cable Interface In the desktop consumption level network interface interfaces are common interfaces BNC interface and RJ-45 interface (similar to the phone interface), there are two interfaces are dual interface. The choice of the interface is related to the network wiring form, in the small shared LAN, BNC port Nic directly connected to othe

connection between different networks, in order to prevent different voltages through the network cable transmission damage device. In addition, data mercury can also play a certain role in lightning protection of equipment. Rj-45 and BNC connector: RJ-45 is a network interface with twisted pair as transmission medium, which is used most frequently in 100mbps network. The BNC uses a thin coaxial cable as

port.Product FeaturesA) highly integrated, high precision;b) Good stability, reliable performance;c) LCD display panel, simple and intuitive.Typical applications1) Metrology Calibration department and research institutes.2) This instrument can be widely used in a variety of scientific experiments, including detonation and particle identification and other scientific tests such as detonation speed, projectile speed, shock velocity, free surface velocity, flying film speed and other detonation pa

chromatic aberration mixed decoding and re-separation process, but also maintain the maximum bandwidth of the Chroma channel, Only need to go through the inverse matrix decoding circuit can be restored to RGB tricolor signal and imaging, which minimizes the video source to the video signal channel between the display imaging, to avoid the cumbersome transmission process caused by the image distortion, so the color output interface is the most current video output interface of the best one.BNC p

network distribution environment, therefore, FDDI interfaces are common in backbone network switches. Now, with the popularization of GE, some high-end gigabit switches are also using this interface.　　4. AUI InterfaceThe AUI interface is used to connect to a coarse coaxial cable. In the early days, the NIC was connected to a hub or vswitch to form a network.The AUI interface is a "D" Type 15-pin interface, used in the ring plate network or bus network, you can use the external transceiver (AUI-

Network Interconnection device lecture Network Interconnection device Overview When connecting a computer to a computer or workstation to a server, in addition to using the connection media, you also need some intermediary devices. What are the main intermediary devices? What role does it play? This is a concern in network design and implementation. We divide commonly used connection devices into the following types: I. network transmission media interconnection Device When a network line is con

categories, which ISA network card and PCI network card more commonly used. The bandwidth of the ISA bus network card is generally the 10M,PCI bus network card bandwidth from 10M to 1000M. The same is the 10M network card, because the ISA bus is 16 bits, and the PCI bus is 32 bits, so the PCI NIC is faster than the ISA NIC. 　　Network Adapter interface type: depending on the transmission media, the NIC appears with the AUI interface (thick cable interface),

read/write of the new socket whenever the accept call on the main thread returns. The advantage of this model is that the program logic is concise and conforms to the human mind; The disadvantage is that the scalability is limited by the number of threads, and as more and more threads are connected, frequent thread switching can seriously slow down performance and have to deal with multi-threaded synchronization issues. Async Model: Asynchronous models generally use non-blocking I

changes, or release of compute resources. The solution given by the author is reactor mode.The reactor mode encapsulates the time-consuming IO resource as a handle object. The handle object is registered in the kernel of the operating system, and the handle object is processed when the object satisfies certain conditions (readable or writable). In reactor mode, the synchronous multiplexer is responsible for handling state changes to the han

overwhelmed to deny the client's request, and even the servers may become paralyzed. NIO is based on reactor, and when the socket has a stream readable or writable socket, the operating system processes the corresponding notification reference program, and then reads the stream to the buffer or writes to the operating system. In other words, this time, is not a connection will be a processing thread, but a valid request, corresponding to a thread, when the connection has no data, there is no wo
