Internet Technology Comparison and Features

The video tutorial discusses three internet access technologies: broadband cable, DSL, and fiber. Broadband cable uses a cable modem and coaxial cable, often provided by cable TV providers, and offers various speed packages. DSL, using phone lines, is cheaper and offers dedicated connections with different types like ADSL, SDSL, and VDSL. Fiber internet, the fastest option, uses light through fiber optic cables, providing high-speed data transmission over long distances but is more expensive and less widely available.

What is a key feature of broadband cable internet?

• It uses fiber optic cables.

• It uses a cable modem with a coaxial cable.

• It is provided by telephone companies.

• It is slower than DSL.

What is a potential downside of using broadband cable?

• It cannot support Wi-Fi connections.

• It can slow down during peak hours due to shared bandwidth.

• It requires a dedicated line for each user.

• It is more expensive than fiber.

What does DSL stand for?

• Dynamic Signal Line

• Direct Service Line

• Data Speed Line

• Digital Subscriber Line

How does DSL differ from dial-up connections?

• DSL is slower than dial-up.

• DSL can carry both voice and data simultaneously.

• DSL requires a separate phone line.

• DSL is only available in urban areas.

Which type of DSL is typically used in homes?

• HDSL

• ADSL

• VDSL

• SDSL

What is a major advantage of DSL over cable?

• DSL is more expensive than cable.

• DSL uses fiber optic cables.

• DSL does not share bandwidth with neighbors.

• DSL is faster than cable.

What is a common feature of both DSL and cable internet?

• Both require a modem with a Wi-Fi router combo.

• Both provide dedicated bandwidth to each user.

• Both use fiber optic cables.

• Both are faster than fiber internet.

What is the primary reason fiber internet is faster than DSL or cable?

• It uses copper wires.

• It uses light to transmit data.

• It is provided by television companies.

• It has a lower latency.

What is a limitation of fiber internet compared to DSL or cable?

• It cannot support high-speed uploads.

• It is slower than DSL.

• It is more susceptible to electromagnetic interference.

• It is not widely available due to limited infrastructure.

Which internet technology uses light to transmit data?

• DSL

• Cable

• Fiber

• Dial-up
