1. 数据传输：网线通过电信号或光信号的方式，将数字信息从一台设备传输到另一台设备。这使不同位置的电脑、服务器等设备之间可以相互通信、交换信息。 2. 连接设备：通过网线，我们可以轻松地将电脑、路由器、交换机等设备连接起来，构建起一个完整的计算机网络系统。 **三、网线的应用领域** 网线在各个领域都有广泛的应用，如家庭网络、企业网络、校园网等。无论是日常生活还是工作学习，都离不开网线的支持。 **四、翻译成英文** **A Brief Introduction to the Development and Role of Network Cables** **1. Development of Network Cables** As the "blood vessels" of the information age, network cables play a crucial role in data transmission. Their development can be traced back to the late 20th century, when the rapid development of computer technology led to a growing demand for network communication, and the technology of network cables has continued to evolve. a. Early Coaxial Cable Stage: Early network communication mainly relied on coaxial cables, which played an important role in early network communication due to their stable transmission performance and good anti-interference ability. b. Rise of Twisted-Pair Cables: With the development of technology, twisted-pair cables gradually replaced coaxial cables. With advantages such as low price, high transmission rate, and easy wiring, twisted-pair cables have become the mainstream choice in modern local area network construction. c. Emergence and Popularity of Fiber-optic Technology: With the further development of the Internet, fiber-optic technology has gradually dominated long-distance network communication due to its higher transmission speed, larger transmission capacity, and longer transmission distance. **2. Role of Network Cables** Network cables play a crucial role in modern society as the foundation of network connections, enabling the connection of computers and other devices and the transmission of data. a. Data Transmission: Network cables transmit digital information from one device to another through electrical or optical signals, allowing different computers, servers, and other devices to communicate and exchange information with each other.

b. Device Connection: Network cables can easily connect computers, routers, switches, and other devices to build a complete computer network system.
