Wired networks are network connections that use physical or wired infrastructure to transmit data between and across networks. These cables provide a stable and reliable means of communication, making wired networks suitable for various applications, from local area networks () within homes and businesses to large-scale data centers and the backbone. Ethernet is the most common wired networking technology for LANs. It uses twisted-pair copper cables (e.g., Cat , Cat 6) to connect devices in a local area network and offers high data transfer rates.
Coaxial cables are commonly used for cable television () networks and broadband connections. Coaxial cables resist interference and are versatile for various applications, including broadcasting, internet access, and security . Fiber-optic cables use light signals to transmit data and offer extremely high , low latency, and are immune to electromagnetic interference. They are often used for long-distance data transmission, providing fast and reliable network connections compared to twisted-pair and coaxial cables.
Applications of wired networks include Local Area Networks (LANs), data centers, and TV and internet services, where coaxial cables deliver broadband services to homes and businesses. The reliability of wired connections makes them suitable for critical applications, while they generally provide consistent speed and lower latency. However, wired networks also have disadvantages, such as the limited of devices because they must be physically connected, and the complexity and cost of installation.
