Chapter 3 Flashcards
What are the components of Coaxial Cable?
Inner conductor (copper core), Insulator (PVC plastic), Braided mesh conductor (aluminum or tin-coated copper), Sheath (PVC plastic)
What are the advantages of Coaxial Cable?
Less susceptible to EMI, Resistant to physical damage, Large existing infrastructure
What are the disadvantages of Coaxial Cable?
Expensive, Not very flexible, Signal quality degrades with multiple splitters
What are the components of Twisted Pair Cable?
Four pairs of copper wires, PVC plastic insulation, Outer plastic sheath, Unshielded Twisted Pair (UTP), Shielded Twisted Pair (STP)
What are the advantages of Twisted Pair Cable?
Inexpensive, Easy to install, flexible, lightweight, Common, tools are readily available, Widely supported network medium
What are the disadvantages of Twisted Pair Cable?
Susceptible to interference, Vulnerable to cable damage and eavesdropping, Low bandwidth
What are the components of Fiber Optic Cable?
Central core (plastic or glass), Cladding, Protective layer, Plastic sheath
What are the vulnerabilities of traditional cables?
Vulnerable to cable damage and eavesdropping.
What is a disadvantage of traditional cables?
Low bandwidth.
What is the central component of a Fiber Optic Cable?
Central core (plastic or glass): Carries the signal.
What is the function of the cladding in a Fiber Optic Cable?
Cladding: Maintains the signal in the core.
What does the protective layer of a Fiber Optic Cable provide?
Protective layer: Provides structural support.
What is the purpose of the plastic sheath in a Fiber Optic Cable?
Plastic sheath: Encases and protects the cable.
What is an advantage of Fiber Optic Cables?
Immune to EMI.
What is another advantage of Fiber Optic Cables?
Highly resistant to eavesdropping.
What is a key benefit of Fiber Optic Cables regarding transmission rates?
Fastest transmission rates.
What is an advantage of Fiber Optic Cables concerning distance?
Greater cable distances without repeaters.
What is a disadvantage of Fiber Optic Cables?
Very expensive.
What is another disadvantage of Fiber Optic Cables?
Difficult to work with.
What is required for attaching connectors to Fiber Optic Cables?
Specialized training required for attaching connectors.
What is a BNC connector used for?
Used in legacy networks, specialized industries, and composite video.
What is the F-Type connector primarily used for?
Used for cable/satellite TV and broadband connections.
What is the RJ11 connector used for?
Used primarily for telephone wiring.
What is the RJ45 connector used for?
Used for Ethernet networks.
