The protocol in iOS is the declaration of a method, stating that no implementation is required, and that the part of the implementation is done by the compliance party.Look at a small example of a protocol: this example is to give two protocols, and then create two types of people to abide by the agreement.Rogue Protocol (ROGUEDELEGATE.H) #import/** Rogue

Recently in the "HTTP diagram" This book, the book mentions the domestic translation of the name of the HTTP protocol, and give some friends to discuss the original link, I looked at a bit of interesting, and I also think that translation for understanding the agreement itself is very important, the collation of some ideas.The full name of HTTP is Hypertext Transfer Protocol, and the main concern is how Tra

TCP (transmission Control Protocol, transmission Protocol) is a connection-oriented protocol,In other words, a reliable connection must be established with each other before sending or receiving data.A TCP connection has to be three "conversations" to build, and the process is very complex and simply describes the simple process of three conversations: A

overturn. My ideal is to be a knowledgeable person with a wealth of professional knowledge, enough to deal with problems at work. In addition to work, you can read books to improve your temperament. 1. what is TCP/IP? If you want to know a person, you can chat from the group where he belongs. Our HTTP protocol is a member of the TCP/IP protocol family. we understand the status of HTTP in the entire netwo

Preface: Because OBJECT-C does not support multiple inheritance, it is often replaced with protocol (protocol). The Protocol (protocol) can only define a common set of interfaces, but cannot provide a specific implementation method. That is, it only tells you what to do, but specifically how to do it, it does not care.

devices constantly detect the network bus, including the time between pauses. When the first domain (address field) is received, each device is decoded to determine if it is destined for itself. After the last transmission character, a pause of at least 3.5 character time is calibrated to the end of the message. A new message can begin after this pause. The entire message frame must be lost as a continuous flow. If there is a pause time of more than 1.5 characters before the frame completes, th

Today's Web program development technology is really a contention, ASP, PHP, Jsp,perl, AJAX and so on. Regardless of how web technologies evolve in the future, it is important to understand the basic protocols for communicating between web programs, because it allows us to understand the internal work of Web applications. This article will be a detailed example of the HTTP protocol to explain, more content, I hope you have patience to see. We also hop

It can be used in communication protocol, data storage and other fields of the language-independent, platform-independent,

In C # writing code, many times you will encounter the HTTP protocol or TCP protocol, here is a simple understanding.The TCP protocol corresponds to the transport layer, and the HTTP protocol corresponds to the application layer, which is inherently not comparable. The HTTP protoco
