block that TCP considers to be sent; (2) When TCP sends a segment, it starts a timer, Used to wait for the destination to acknowledge receipt of this segment; If this acknowledgement is not received in time, the TCP sender will resend the message segment (timeout retransmission); (3) TCP sends a confirmation after receiving a data from the other end of the TCP connection, but this acknowledgement is not sent immediately. Instead, it is deferred for a fraction of a second before it is sent; (

The tutorial uses radial blur to make sunlight transmission. When making a picture of the highlight part of the selection, and then use the Blur filter selection of the appropriate angle blur, and then the overall adjustment of brightness and detail can be. Original Final effect 1, open the original image, implementation: Selection-color range, select High light, click OK; 2. Copy layer. Ctrl + J two times, copy Layer two times. Cla

Server-Side client communication After the connection to the server is established, we can send and receive data through this connection. Ports and ports transmit data in streams, because almost any object can be saved to the stream, so you can actually transfer any type of data between the client and the server. To the client, the data is written to the stream, the data is sent to the server, the data is read from the stream, and the data is received from the service side. For the server, the

USB transfer protocol. -- Arvin, usb transmission arvinQuestion 1: What is the structure of the USB transmission line? Answer 1: a usb transmission line consists of four lines: Ground Wire, power cord, D +, and D-. D + and D-are differential input lines, it uses a voltage of 3.3V (note that it is different from the 5 V level of CMOS), and the power cord and groun

With the rapid development of video monitoring technology, the customer's requirements for video monitoring products are constantly increasing. The functional requirements are more complete and stable, and the performance requirements are clearer and more accurate. At the same time, how can we see a person's facial features in shopping malls, banks, and other important monitoring sites? How can we find out the license plate of a high-speed vehicle? How can we quickly and accurately find the targ

The aveon interface supports burst transmission. In burst mode, multiple transmissions are processed as one unit, rather than each data unit as an independent transmission. Burstable transmission maximizes the throughput of the slave port and achieves the highest efficiency when the slave port processes multiple data units from one master port. Burst

Differences between synchronous transmission and asynchronous transmission 2 recommended The difference between synchronous and asynchronous synchronization-that is, when you ask me to go to dinner, I will go to dinner with you when I hear it; if I don't hear it, you will not stop calling until I tell you to hear it, to eat together. Asynchronous-you call me and eat it yourself. After receiving the message,

The total amount of data transmitted or transmitted by a channel per unit of time is called the channel transmission volume. However, in actual application environments, all channels will suffer different losses, we call this loss a channel surplus. In our Integrated Wiring System, effective use of channel surplus can greatly improve network transmission performance. Based on the experimental results, the i

Abstract: With the increasingly mature video compression technology, digital video monitoring products have gradually become the mainstream of the market. People Urgently hope that the network technology can be successfully applied to the field of digital video surveillance, so that people can achieve remote monitoring through the network. In this context, the study of "network-based digital video transmission" is becoming increasingly important. This

With the advancement of optical communication technology, the access network has gradually evolved from a common analog user loop to an optical access network (OAN). On the other hand, due to the maturity and advancement of SDH technology, it has gradually changed from long-distance network to relay network, finally, it is widely used in access networks. 1 ). The transmission network is the platform of all business layers including the support layer,

Monitoring of overhead transmission lines supported by 3G/4G + Mesh combination The safe and stable operation of transmission lines is an important guarantee for national economy and livelihood. However, transmission lines have been affected by man-made damage, climate and geological changes, as well as illegal buildings, super-high-growth plants, birds, snakes,

As this chapter is mainly an introductory topic, I will not talk about it much. Here is an overview of the Internet! 【Note] Reprint address: http://www.cnblogs.com/hill/archive/2006/10/12/527499.html China Mobile and China Unicom have implemented GPRS networks and CDMA networks covering a large number of regions. It is possible to achieve data transmission through wireless networks. Wireless modem uses GPRS and CDMA modules to transmit data throug

talked about the HTTP caching mechanism and the HTTP Content entity encoding compression mechanism, and when it comes to entity encoding compression, it also mentions a transmission code that allows us to optimize the way we transmit. Entity encoding and transmission coding are mutually reinforcing, and we usually use them together.This article will talk about the tran
