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 applications, from local area networks (LANs) within homes and businesses to large-scale centers and the internet backbone. Ethernet is the most common wired networking technology for . It uses twisted-pair copper cables (e.g., Cat 5e, Cat 6) to connect devices in a local area network. Fiber-optic cables use signals to transmit data and offer extremely high bandwidth, low latency, and immunity to electromagnetic interference, making them ideal for long-distance data transmission.
Coaxial cables are commonly used for cable television (CATV) networks and broadband connections. They provide higher bandwidth than twisted-pair cables but are not as fast as cables. Coaxial cable is a common electrical cable used for transmitting signals like cable TV, satellite TV, and surveillance camera feeds. It has a central , insulating layer, metallic shield, and outer insulation. Wired Ethernet connections are prevalent in homes and businesses, connecting devices like computers, printers, and . Data centers often use wired connections, primarily fiber-optic, to interconnect servers and storage devices, providing high-speed communication.
Wired connections are highly and less susceptible to interference, making them suitable for critical applications. They typically provide consistent and stable data transfer rates, which is an advantage over wireless networks, which can experience variability. Additionally, wired networks are more secure by nature, as they are harder to compared to wireless signals. However, they do have disadvantages such as physical limitations, installation complexity, and ongoing maintenance requirements. Cables have limited reach, which makes them impractical for larger spaces, and the cost of purchasing and maintaining the physical cabling infrastructure can be higher compared to wireless networks.
