计算机网络常用术语缩写1. IP: Internet Protocol（互联网协议）IP是一种用于在互联网上发送和接收数据包的协议。

它定义了互联网上每个设备的唯一地址，以便进行通信。

2. TCP: Transmission Control Protocol（传输控制协议）TCP是一种面向连接的协议，用于在互联网上传输数据。

它负责将数据分割成小块，确保它们可靠地传输，并在需要时重新组装。

3. UDP: User Datagram Protocol（用户数据报协议）UDP是一种无连接的协议，用于在互联网上快速地传输数据。

它不负责分段、重传和重新排序数据，因此速度较快，但可靠性较低。

4. DNS: Domain Name System（域名系统）DNS是一个用于将域名解析为IP地址的系统。

当我们在浏览器中输入一个域名时，DNS将域名转换为对应的IP地址，以便浏览器能够找到正确的服务器。

5. HTTP: Hypertext Transfer Protocol（超文本传输协议）HTTP是一种用于在Web上传输文本、图像、视频和其他资源的协议。

它是一个无状态的协议，即服务器不会存储任何关于客户端的信息。

6. HTTPS: Hypertext Transfer Protocol Secure（安全超文本传输协议）HTTPS是在HTTP基础上添加了安全功能的协议。

它使用SSL/TLS加密来保护数据的传输，使通信变得更加安全。

7. LAN: Local Area Network（局域网）LAN是用于连接设备在一个局限空间内进行数据传输的网络。

它通常用于家庭、办公室和学校等小范围的网络。

8. WAN: Wide Area Network（广域网）WAN是用于连接不同地理位置的局域网的网络。

它通过公共或专用线路连接远程设备，使它们能够进行通信。

9. VPN: Virtual Private Network（虚拟专用网络）VPN是一种通过公共网络建立专用网络连接的技术。
