- Detailed explanation of Socket
- We are well aware of the value of information exchange, so how do processes in the network communicate? For example, when we open the browser to browse the web every day, how does the browser process communicate with the web server? When you use QQ to chat, how does the QQ process communicate with the server or the QQ process where your friends are? Do all these rely on sockets? So what is a socket? What are the types of sockets? There are also basic functions of socket, which are what this article wants to introduce. The main contents of this article are as follows:

- The difference between TCP/IP, HTTP and Socket
- The network is divided from bottom to top into the physical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer. Through preliminary understanding, I know that the IP protocol corresponds to the network layer, the TCP protocol corresponds to the transport layer, and the HTTP protocol corresponds to the application layer. The three are essentially incomparable. Socket is the encapsulation and encapsulation of the TCP/IP protocol. Application (programmer level). It can also be said that TPC/IP protocol is a transport layer protocol, which mainly solves how to transmit data in the network, while HTTP is an application layer protocol, which mainly solves how to package data.

- Simple understanding of Sockets
- To understand sockets, you must first familiarize yourself with the TCP/IP protocol family. TCP/IP (Transmission Control Protocol/Internet Protocol) is the Transmission Control Protocol/Internet Protocol, which defines how hosts connect to the Internet and how data is transmitted between them. Standard, literally speaking, TCP/IP is the collective name of TCP and IP protocols, but in fact, TCP/IP protocol refers to the entire TCP/IP protocol family of the Internet. Different from the seven layers of the ISO model, the TCP/IP protocol reference model classifies all TCP/IP series protocols into four abstraction layers

- Thoughts triggered by a distinct question
- The data here has the following characteristics: in one DepartmentId, there may be multiple Names, and vice versa. That is to say, Name and DepartmentId have a many-to-many relationship. Now I want to implement such a query: after sorting by DepartmentID (the first step), then obtain the unique values of the Name column (the second step), and retain the relative order after the first step. In this example, the three values that should be returned are: ACB

- Oracle-distinct usage
- The distinct keyword is used to filter out redundant duplicate records and keep only one, but it is often only used to return the number of unique records, rather than using it to return all values of non-duplicate records. The reason is that distinct can only be solved by double loop query, which will undoubtedly directly affect the efficiency of a website with a very large amount of data.

- Usage of distinct in SQL (analysis of four examples)
- The distinct keyword is used to filter out redundant duplicate records and keep only one, but it is often only used to return the number of unique records, rather than using it to return all values of non-duplicate records. The reason is that distinct can only return its target field, but cannot return other fields. Next, I will share with you the usage of distinct in SQL through this article. Friends who need it can refer to it.

- Usage of distinct in SQL
- Tables may contain duplicate values. This is not a problem, but sometimes you may want to just list distinct values. The keyword distinct is used to return uniquely distinct values.

- The difference between strings and arrays in C language
- The elements of an array can be of any type, and a string is a special type of array that uses a well-known rule for determining its length. There are two types of languages, those that treat strings simply as an array of characters and those that treat strings as a special type. C belongs to the former category, but there is one addition, that is, the C string is terminated with a NUL character. The value of an array is the same as the address of the first element in the array (or a pointer to that element), so generally a C string and a character pointer are equivalent.
