Course Introduction：React is a one-way data flow, not two-way; one-way data flow means that after the data is changed on a node, it will only affect other nodes in one direction, while two-way binding refers to the relationship between the data model and the view Binding will affect other nodes in different directions. The performance in React is that data is mainly passed from parent nodes to child nodes through props, so it is a one-way data flow.

Course Introduction：TCP connection, three-way handshake: The three-way handshake and four-way dissolution process of the TCP connection: When the client and server use the TCP connection to transmit data, they need to go through the three-way handshake to establish the connection and the four-way handshake to disconnect. As shown in the figure below, the above figure describes the detailed process of TCP connection from establishment to disconnection. The specific message details will be discussed below. During the TCP three-way handshake to establish a connection, the client first sends a request packet with SYN=1 and Sequence=p to the server. If the server agrees to grant the client the link, it sends a response packet with ACK=p+1, SYN=1, and Sequence=q. Finally received the service on the client

Course Introduction：The differences between three-way frequency and two-way frequency include different functions, frequency differences, different purposes, and mutual relationships. Detailed introduction: 1. The three-way frequency mainly determines the transmission speed and stability of the peripherals, and the two-way frequency mainly determines the speed and performance of the processor; 2. The three-way frequency is usually expressed as a lower frequency, measured in MHz. Unit, the two-way frequency is usually expressed in higher frequency, in megahertz or gigahertz; 3. The purpose is different, the purpose of the three-way frequency is to reduce the frequency of peripherals to reduce data transmission errors and conflicts, and improve the system stability and compatibility, etc.
