2.7 Cable Connections Flashcards
What does DOCSIS stand for?
Data Over Cable Service Interface Specification.
What type of network do cable modems operate on?
Hybrid Fiber-Coaxial (HFC) network.
What is the main advantage of an HFC network?
Uses a mix of fiber-optic and coaxial cables for high-speed broadband.
What frequencies do cable modems use for upstream data?
5 - 42 MHz.
What frequencies do cable modems use for downstream data?
50 - 860 MHz.
What is the latest DOCSIS standard that supports gigabit speeds?
DOCSIS 3.1.
What is the primary advantage of cable modems over DSL?
Faster speeds and more stable performance.
How does cable internet share infrastructure with TV?
Both use the same coaxial cables for transmission.
Why is DOCSIS important for cable internet?
It standardizes how cable modems transmit and receive data.
What is a major benefit of DOCSIS 3.1?
It enables gigabit-speed internet.
Why do cable modems provide better performance than DSL?
They have higher bandwidth capacity and are less affected by distance.
What technology competes with cable modems for high-speed internet?
Fiber-optic internet (FTTX).
Why is cable internet widely available?
It leverages existing cable TV networks.
What type of cables do cable modems use?
Coaxial cables.
Why do cable modems remain popular?
They offer high speeds, reliability, and wide availability.
