Cable refers to a physical medium typically made of copper or fiber optic materials that is used for transmitting data, signals, and information. It is commonly utilized in telecommunications and networking systems to connect devices and enable communication between them.
Types of cables
- Coaxial cables: These cables consist of a central conductor surrounded by an insulating layer, a metal shield, and an outer insulating layer. They are often used for transmitting cable television signals.
- Twisted pair cables: These cables contain pairs of insulated wires twisted together. They are commonly used for Ethernet connections and telephone lines.
- Fiber optic cables: These cables transmit data in the form of light pulses through thin strands of glass or plastic fibers. They offer high-speed and long-distance communication, often employed in internet connections.
