6.3 Wired and Wireless Networking

A cable that provides connectivity between network devices. A common network cable connects a computer's network interface with a wall jack.

• Network Cable

• Coaxial Cable

• Twisted Pair Cable

• Electromagnetic Interference

A cable that provides transmission on a network through its inner wire in the form of electrical signals

• Network Cable

• Coaxial Cable

• Twisted Pair Cable

• Fiber Optic Cable

A cable that transmits data through electrical signals and provides better signals because of its unique eight plastic-coated copper wires that are twisted into four pairs.

• Fiber Optic Cable

• Registered Jack 11 (RJ-11) Interface

• Twisted Pair Cable

• Electromagnetic Interference

When an electrical current passes through any kind of copper wire, creating an electromagnetic field just outside the wire.

• Router

• Switch

• IEEE 802 Standards

• Electromagnetic Interference

The different types of twisted pair cabling that are defined by the several aspects of a cable including its transmission specifications and intended use. Common categories include Cat 5e and Cat 6.
