Intel is initially deploying optical fibers that will use laser and light to move data faster within the computer, replacing the old and slow wire technology currently used by most computers.
Intel's silicon photon technology will be applied on the motherboard and rack layers and use light to transmit data between storage, network, and computing resources. Light is considered to be a much faster transmission method than copper cables.

Compared with version 2.7.0 (released about two weeks ago), Pidgin2.7.1 has not brought many improvements, but it has brought about a problem that MSN users have been waiting for more than three years to fix the MSN file transmission vulnerability. Until now, Pidgin doe
When accessing webserivice, if the data volume is large, the data transmission will be slow. To increase the speed, we will think of compressing the data. First, let's analyze it.
When data is transmitted in webserice, dataset is generally used for data transmission. The execution process is to first convert dataset to XML for transmission. The format of dataset
I was recently depressed by the load type and timestamp of RTP. After debugging for nearly a week, I finally solved the problem. Let's look back, I found that the main reason is that I did not really understand the meaning of the load type and timestamp in the RTP protocol. Although RTP transmission is supported by Jrtplib and Ortp databases, one is the c ++ interface and the other is the c language interface. Each has its own characteristics and its
The edge transmission service role should be no stranger to everyone, especially to friends who are familiar with lync. When deploying the lync server product in an enterprise, the edge role must be deployed. However, in exchange, few enterprises deploy edge roles. As for why, you have to take a good look at the role of edge servers in exchange and lync. Next, let's take a look at the analysis:
1. Analysis of the Role of edge servers in lync and excha
The book connects to the text and starts to toss about the DMA transmission of the ADC. Because everyone is talking about DMA, even the st example uses DMA.
The data collected by the ADC is stored in a fixed register. When multiple channels are sampled in the conventional sampling method, DMA can be used to avoid data loss. When the DMA function of the ADC is enabled, a DMA request is sent when each channel is converted. The DMA mode cannot complete

7.9.2 encrypted transmission using SSL (1)
By default, IIS uses http to transmit data in plain text. Web services use HTTP to transmit data. The data transmitted by Web Service is plain text in XML format. Without any encryption measures, users' important data is easily stolen. How can we protect these important data transmitted on the network?
The Chinese full name of SSL (Security S
The usb_stor_bulk_transfer_sglist () function is confusing. We have mentioned that sglist is used to improve transmission efficiency. As we know, SG aims to transmit a bunch of discontinuous buffers in one DMA Operation. In fact, this is not the case in the story of USB. However, if you don't care about the behavior in the USB core, it doesn't matter.
Row 3 and row 3 do not pass data if you exit or break the link.
Then in Row 3, The usb_sg_init () fun
There are many ways to transmit data between the device and the device. For example, when a teacher presents a slide on the podium, we can use a mobile phone camera to take a picture, however, the image data obtained by this method may not be clear. In addition, it is not convenient to copy the data to the teacher after class. Contemporary information sharing methods include technologies like cameras reading QR codes, but these are not helpful for transmissi
I am very sad to write this short article about some understandings of network transmission. How to transmit data quickly between multiple nodes was just optimized from the perspective of data transmission, it would be a pity to give me another chance... Let's talk about the following points: first, we should try to improve the degree of parallelism, and each node transmits data to other nodes that do not h
Asynchronous transmission mode, also known as cell relay. An ATM adopts a connection-oriented exchange mode, in which the Unit is credit. Each cell is 53 bytes long. The header occupies 5 bytes. ATM is ideal for implementing various QoS, supporting both connected businesses and unconnected businesses. Is a model of broadband ISDNB-ISDN) technology.

AMI encoding1 yards is usually called the pass number, 0 yards is called the empty number, this is used in the early telegraph communication in the name. From the morphological perspective, it is a three-state signal, so the AMI code is a pseudo-three-in-one code.First, the coding rules:0 in the 0 transmission code in the message code+ 1,-1 alternating in the 1 transmission code in the message codeFor examp
Communication between people is now mostly done through instant messaging, and these tools have the basic function of file transfer. Then use this function after two development by using Instant Messenger, the following is an example of the Anychat interactive development platform of the leading audio video technology in China, which realizes the file transfer function. Anychat supports the file transfer speed limit feature since the Anychat SDK version V4.1.0.1. By default, anychat file transfe
SSH can transmit data by encrypting the online packets. SSH can be used to encrypt all transmitted data, and no useful information can be obtained even if someone intercepts the data. At the same time, data is compressed, which greatly speeds up transmission. In short, the use of SSH ensures that data transmission is secure and the transmission efficiency is high
First, the storage, transmission and processing of image dataImage data can be stored in external memory, display memory or computer memory medium 3 medium, different storage media for different purposes. The image is stored in the display memory to show that the displayed image intelligence is viewed in the boot state, and disappears after the shutdown is called a soft copy. To facilitate fast access to image refreshes, the data in the display memory
GPRS data transmission plane
Compared with GSM, GPRS reflects the characteristics of group exchange and group transmission, that is, data and signaling are based on a unified transmission platform. As shown in the figure above, the Protocol structures below the transfer layer (LLC) are the same for data and messaging on Several Interfaces passed by data
TCP and UDP transmission principles of Socket communication in Android
1. Socket Communication
Android can communicate with the server in two ways: Http and Socket. The biggest difference between the two is that the http connection uses the "request-response method", that is, a connection channel is established during the request. After the client sends a request to the server, the server can return data to the client.
In Socket communication, TCP/IP-
