The tester shocould, at the very least, accurately report the problem that he or she comes into SS when testing. often a program, or a set of programs, passes through several intermediate steps before concluding. if the program runs into an error, surely the tester can attempt to determine the steps that were completed before aborting. this not only gives the developer a clue about what cocould have gone wrong, but it also helps

People familiar with rams also complain about availability.Iso25010 (figure 3), the next generation of ISO9126, was released several years ago, but it has not been recognized and understood yet. I have never used it. I usually tend to stick to things that have been proven useful, rather than using new versions, such as a standard. Most standards have almost no value added. I quickly browsed iso25010, but it didn't attract me.

, the host does not return the ICMP time exceeded message because it is already the destination. How does traceroute know that the destination has arrived?When traceroute sends a UDP batch Rams to the destination, the port number it chooses to deliver is a number that is not used by general applications (more than 30000 ), therefore, when the UDP datax arrives at the destination, the host will return an "ICMP port unreachable" message.

This layer is responsible for obtaining all information. Therefore, it must track data unit fragments, unordered data packets, and other possible risks during transmission.

Cookbook: Recipe 13.1. Passing Messages with Socket into rams
I recently spent some time learning network-related knowledge. Today I will learn how to use python to transmit data on two machines.
Problem:
Do you think it is mysterious that tools like msn and qq on the Internet transmit data between multiple machines? Do you want to transfer data between two machines? Today, let python tell us the basic principles. Of course, it's just a simple und

Explanation
SOCK_STREAM
Provides sequenced, reliable, two-way, connection-based byte streams with an OOB data transmission mechanic. Uses TCP for the Internet address family.
SOCK_DGRAM
Supports extends rams, which are connectionless, unreliable buffers of a fixed (typically small) maximum length. Uses UDP for the Internet address family.

The socket has three attributes: domain, type, and protocol, which correspond to different domains. The socket also has an address as its name.
Domain specifies the protocol family used for socket communication. The most common domain is af_inet, which indicates the network socket. The underlying protocol is the IP protocol. For Network sockets, because the server may provide multiple services, the client must use the IP port number to specify specific services. Af_unix represen
