learning python network programming

Python network programming, TCP/IP client and server, 2015 python I have never been very clear about the definition of the server, and I have only a vague feeling about what the server/client architecture is. I recently started to learn about the relationship between some servers and clients. A server is a service prov

underlying file system to fetch data, two sockets process running on the same machine, you can access the same file system to complete the communication indirectlysocket family based on network typeSocket family name: af_inet(There are also af_inet6 used for IPv6 and some other address families, but they are either used only on a platform, or have been discarded, or are rarely used, or are not implemented at all, and Af_inet is the most widely used o

Based on the understanding of the basic syntax of Python, it is possible to freely assemble a variety of advanced functions that you need.Because of the characteristics of Python language, the implementation of various functions will be very fast.The network becomes one of the advanced features that Python has. Need to

layer: The socket communication process is automatically processed, such as the above transmission path selection, data validation process, etc. are hidden inside the socket. In short, for us, sockets are the tools that are provided to us, and we only need to use sockets to program them. In the process of writing software, it is necessary to determine the data transfer rules between the service and customer base according to the program characteristics, which is the application layer protocol.

arrival, reliability and data repeatability can not be guaranteed. The datagram preserves the data boundaries, which means that the data is not split into small chunks like a connection-oriented protocol.The primary protocol for implementing this connection is the User Datagram Protocol (that is, UDP). To create a UDP socket, you specify that the socket type is SOCK_DGRAM when it is created. Because these sockets use Internet protocols to find hosts in the
