FTP client to connect to the FTP server on the right to upload files. Data is stored in the form of a class Stack. when the data is stored on the target machine, the underlying data is obtained first, from the bottom to the top, in line with the features of the stack. Step 1: Prepare data files at the application layer, call the Windows API to notify the transport layer to establish a

client sockets. And what we usually say the most socket is what, in fact, the socket is the TCP/IP protocol encapsulation, thesocket itself is not a protocol, but a call interface (API). With the socket, we can use the TCP/IP protocol. In fact, the socket is not necessarily associated with the

I. TCP/IP Beijing and introductionIn the 70 's, with the development of computer technology, computers users realized that it was necessary to connect computers from all over the world to play a more important role in computer. But the simple connection is not enough, because the computer can not communicate. Therefore, the design of a common "language" to communicate is necessary to be less, then the

Repost TCP/IP protocol simple analysis First, TCP/IP and IP are two different protocols. They are divided into different layers in the layer-7 network model. IP is the network layer protocol, and

package can reach the target machine correctly. Through this process, IP and other network layer protocols are used for data transmission. Without a network tool, you cannot see the IP address that works in the system. Application Layer Protocol On the contrary, application-layer protocol users can see it. For example, you can see the file transfer protocol (FTP. A user requests a connection to another com

For the client program, it implies that when we terminate a customer service program and immediately restart the application, the customer program will not be able to reuse the same local port. Generally, the server is passively disabled and does not enter

run an interactive application and another application such as f t p to send or receive 1 0 2 4 bytes of data, in general, you have to wait half the time (533 MS) to send the grouped data of the interactive application. Studies on humans show that the interaction response time exceeds 1 0 0 ~ 200 ms is considered to be a bad problem [Jacob bson 1990a]. This is the round-trip time after an interactive message is sent until the response message is received (usually a echo character is displayed.

After more than half a year of embedded work and learning, I improved a lot, but at the same time I also faced with the problems of their own clear:1. In practice, the theoretical foundation is not strong2. The algorithm, the data structure cognition is too shallow3.
