Structured Cabling was the first generic cabling system that emerged 20 years ago to meet the needs of modern business buildings for communications, faxes, and data networks. In addition, structured cabling needs to meet the needs of flexible and changing business environments, and can be flexibly configured after installation, so it is favored by users. 1. support frequent movement of office environments2. Support for future staff increase3. Support for future applications4. Reduce operation co

large catheter or tray (which is usually a very expensive proposition ); 2 If there is space in the catheter, you can cut off the 15-pin connector on one end of the VGA cable and want the cable to be rolled back. Then, if your cable reaches your destination, you must reinstall the 15-pin connector to connect to the VGA cable. The quality of the on-site connection may not meet the requirements of the factory standards. Therefore, the video quality may be impaired. Wiring large Cables like VGA ca

With the extensive use of computers, network and Integrated Wiring have naturally become a hot topic. Correct design and layout of a network system not only improves the speed and reliability of communication, but also greatly improves the work efficiency; in cabling, the carrier for signal transmission-transmission media must be used. In a complete and stable network environment, the selection and correct

Voice communication over the Internet is a very complex system engineering and has a wide range of applications. Therefore, many technologies are involved. The most fundamental technology is the VoIP (Voice over IP) technology, it can be said that Internet voice communication is the most typical and promising application area of VoIP technology. This article describes the basic transmission process of VOIP.The traditional telephone network transmits v

Universal Serial Bus (USB) since the advent of the 1996, unified PC external interface, and extended to a variety of consumer products, has long become a part of modern life. Published in 2000, the USB 2.0 high-speed specifications, providing 480Mbps transmission rate, has been more than 10 years of history, with the high-resolution audio-visual applications gradually popularized, frequently gbyte level of audio-visual materials, USB 2.0 bandwidth has

The holiday is over, and I return to school again. I have been doing WinForm before, and now I have finished it. Then I am going to apply it on the Internet. After a long period of exploration and study, I finally got a rough outline in my mind, understand the General Principles An instant messaging software similar to QQ is used as an example. There are a lot of chat program source code that can be downloaded on the Internet, including the QQ series of source code that implements file

real-time audio and video domain UDP is the kingly The Transport layer scheme for real-time audio and video interaction on the Internet has two types: TCP (e.g. RTMP) and UDP (e.g. RTP). The TCP protocol provides a relatively reliable guarantee for data transmission between two endpoints, which is achieved through a handshake mechanism. When the data is passed to the receiver, the receiver checks the correctness of the data. The sender only receives t

The development of wireless technology has led to a wide variety of technical applications. Of course, video is essential. Next, we will introduce a wireless video transmission technology called coofdm. I hope this article can broaden your horizons. Coofdm Wireless Video Transmission Technology is a multi-carrier Digital Communication modulation technology used in military radio

More and more people are using wireless networks to watch movies and video chats. The limitations of wireless networks are shown. The transmission speed in wireless networks is greatly affected, especially video files, this article focuses more on speed and introduces how to improve the speed of wireless video transmission. I. In addition to the basic 802.11n functions used for video optimization, we should

When learning the FTP protocol, we learned that the work done in different protocol modes is different, so today we will explain the FTP transmission mode. First, let's take a look at the two FTP modes and how the protocol switching between them is completed. I. Two FTP Modes The two FTP modes are active mode PORT and passive mode PASV ). If the active mode is adopted, the FTP software requests the server to connect to it. If the passive mode is adopt

1. Applicable H.264 Video Transmission Mechanism RTP is discussed earlier. Protocol and the basic stream structure of H.264, how can we use RTP to transmit H.264 videos? An effective method is to strip each NALU from the H.264 video, add the corresponding RTP Header before each nalu, and then send packets containing the RTP Header and NALU. The following describes the RTP Header and NALU respectively. Complete RTP The Fixed Header Forma

Multiple-to-multiple message transmission 1. Summary Message Passing is widely used in various websites. This function is also essential for a website. Common messaging applications include @ me in Sina Weibo,

has not explicitly stated this, it does not mean self-emergence (data goes directly to the destination through a fully established network, instead of route-based jump-by-Jump !). My disagreement with the author is that the all-established network is a transmission network rather than an addressing network, which I will discuss in detail below. In short, the author has repeatedly said that the network should not be implemented based on computers, and

When it comes to HTTPS, I have to mention HTTP (Hypertext Transfer Protocol), the most extensive network protocol on the Internet, with its technical architecture, Protocol features, Protocol principles, Baidu or Google, which are explained in detail. and HTTPS (Hyper Text Transfer Protocol over Secure Socket layer) More on this s, SSL encryption, usually understand that HTTPS is HTTP to join the SSL encryption layer into a security-targeted HTTP transmissio
