网络编程中的异常处理和错误调试

# 第一章：网络编程基础概述

## 1.1 网络编程概念及应用
Network programming, also known as socket programming, is the design and writing of software programs that run on interconnected devices to communicate with each other. It allows different devices to exchange data and communicate over a network, such as the Internet.

Network programming is widely used in various applications, including web development, server-client communication, online gaming, and IoT (Internet of Things) devices. It plays a crucial role in enabling the seamless flow of data and information across different platforms and devices.

## 1.2 网络编程的重要性
The significance of network programming lies in its ability to facilitate real-time communication and data transfer between connected devices. It empowers the development of distributed systems, client-server architectures, and cloud-based applications. Furthermore, network programming is essential for developing scalable and responsive software systems that can handle a large volume of simultaneous connections.

## 1.3 常见的网络编程技术和工具
In the realm of network programming, various technologies and tools are commonly utilized, including:
- Socket programming libraries (e.g., `socket` module in Python and `java.net` package in Java)
- Web frameworks (e.g., Django and Flask in Python, Spring in Java)
- Protocols such as HTTP, TCP, UDP
- Network debugging tools (e.g., Wireshark, tcpdump)

These technologies and tools form the building blocks for developing robust network applicati
