Wired networks are network connections that use physical or wired infrastructure to transmit data between devices and across networks. These cables provide a stable and reliable means of communication, making wired networks suitable for various , from local area networks (LANs) within homes and businesses to large-scale data centers and the internet backbone. Ethernet is the most common wired networking technology for LANs. It uses twisted-pair copper cables (e.g., , Cat 6) to connect devices in a local area network and offers high data transfer rates.
Coaxial cables are commonly used for cable television (CATV) networks and broadband internet . Coaxial cables have a central conductor, insulating layer, metallic shield, and outer insulation, making them versatile for various applications, including broadcasting and internet access. Fiber-optic cables use to transmit data, offering extremely high bandwidth, low latency, and immunity to electromagnetic interference. They are often used for long-distance data transmission, internet backbones, and high-speed connections between data centers.
Wired connections are highly reliable and less susceptible to , making them suitable for critical applications. They offer consistent and stable data transfer rates without the variability associated with wireless networks. However, wired networks have limitations, such as physical where cables have limited reach and installation complexity, making them impractical for large spaces. Additionally, the cost of purchasing and maintaining the physical cabling infrastructure can be higher compared to wireless networks.
