Wired communication technology refers to the transmission of data over a physical medium, such as cables or wires. This technology is often used in telecommunications networks, television networks, and computer networks.

There are several types of wired communication technologies, including:

Ethernet: This is a common method of networking computers in a local area network (LAN). Ethernet cables are used to connect devices within a local area, such as a home or office.

Coaxial Cable: This type of cable is used by cable TV and is also common in older Ethernet networks. It has a single copper conductor at its center.

Fiber Optic Cable: This type of cable uses light to transmit data at high speeds and over long distances. It is commonly used in telecommunications and high-speed internet connections.

Telephone Lines: These are used for voice communication, but can also be used for data transmission in dial-up and DSL internet connections.

USB (Universal Serial Bus): This is a common method for connecting peripheral devices to a computer. It can also be used for short-distance communication between devices.

HDMI (High-Definition Multimedia Interface): This is used for transmitting high-quality video and audio signals between devices, such as a computer and a television.

Power Line Communication: This technology uses electrical wiring to simultaneously carry both data and electric power.

Each of these technologies has its own advantages and disadvantages in terms of speed, cost, ease of installation, and reliability
