"OSI layer Seven Protocol" Application Layer An application that communicates with other computers, which is the communication service of the corresponding application. For example, a word processor without a communication function would not be able to execute the code of communication, and the programmer working on the word processing did not care about the 7th layer of the OSI. However, if you add an option to transfer files, the programmer of the

In the previous article, "Master Programmer's Training: TCP, message subcontracting and protocol design" discusses some of the topic of protocol design, here to add to the HTTP protocol and binary protocol comparison.The HTTP protocol is a text

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

An agreement that must be followed by the entrusting party and the agent. Delegate by (

SMTP is used to deliver e-mail messages on the Internet. Document RFC821 provides all the details of the agreement. But you just have to remember the following-the basic commands and methods of the agreement. The principle of the protocol is simple. Nothing more than a client computer sending a command to the server, and then the server returns some information to the client computer. The commands sent by the guest room and the server response are s

Introduction There are many types of caching: Server caching, Third-party caching, browser caching, proxy caching, gateway caching, database caching, and so on. The browser cache is the least expensive because the browser cache relies on the client and consumes almost no server-side resources. Today's summary is also associated with browser caching. Browser caching must be very familiar, simply that the browser on the disk to the most recent user requested data storage, when we request this page

AJP13 is the directional package protocol. For performance reasons, the binary format is used to transmit readability text. The Web server is connected through a TCP connection and a servlet container. To reduce the cost of process generation sockets, the Web server and the servlet container try to maintain a persistent TCP connection and reuse a connection for multiple request/reply loops. Once a connection is assigned to a specific request, it is no

UDP belongs to the transport layer together with the TCP mentioned earlier. UDP differs from TCP in that it is a non-connection-oriented protocol, that is, when both parties communicate with each other, they do not need to establish a connection beforehand. So the UDP header saves a lot of fields, and the UDP header is only 8 bytes. The UDP header consists of the following: The UDP header contains only the source port and destination port, plus th

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

This time, we will mainly explain the issues related to the daytime protocol and time protocol. Let's take a look at the content of the daytime protocol and time protocol. In a LAN, many systems require that each computer maintain time consistency. The WIN2000 system provides the time synchronization function with the

8.1 Address Mapping At the network level, hosts and routers are identified by their logical addresses (IP addresses). The logical address is unique globally. At the physical level, hosts and routers are identified by local addresses. 8.1.1 Static Mappings Map physical and logical addresses to a single table. Save to each machine, Cons: Need to update 8.1.2 dynamic Mappings periodically Use protocols to find static addresses based on logical addresses. There are currently two types of protocols:
