Swift protocol and swift Protocol The protocol in Swift is also called in object-c, but in other languages it may be called Interface (such as java) or pure virtual function. In fact, it all means. The Protocol is mainly used to define uniform methods and attribute names, but does not implement any functions. Only the

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.

TelnetWhat is Telnet protocol?Telnet Server Software is our most commonly used Telnet Server software and is a typical client/server model service that uses the Telnet protocol to work. So, what is the Telnet protocol? What features does it have?Telnet is a protocol located at layer 7th of the OSI model---application l

I. Overview A protocol is a delegate (delegate)/proxy, which is an object that provides an opportunity to respond to changes in another object or to affect the behavior of another object. A protocol can only be used for one purpose, that is, to declare a heap of methods for an inherited class. The base class adheres to the Protocol, and its deriv

Put the three Protocols together for learning because these three protocols are on the same layer. ARP is used to find the MAC address of the Ethernet NIC of the target host, and the IP address carries the message to be sent. The data link layer can get the data transmission information from ARP, and get the data information to be transmitted from the IP address.1. IP protocol The IP protocol is the core of

What is the industrial Internet of things?In short, it is the specific application of the Internet of things in industrial control.What is SSL/TLS?SSL (secure Sockets layer Secure socket), and its successor Transport Layer Security (Transport layer Security,tls) is a security protocol that provides security and data integrity for network traffic. TLS encrypts the network connection with SSL at the transport layer. Most of the Internet login is the use

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, while the HTTP protocol corresponds to the application layer, in essence, there is no comparability between the two. The HTTP

In terms of email, POP and IMAP are the most famous protocols. I don't need to talk about the POP protocol. Many users will be familiar with this protocol when setting some mailbox binding functions. Some friends may not understand the IMAP protocol. Here we will make a comparison between the two Protocols. POP ProtocolPOP stands for Post Office
