Cable Types And Network Focus Flashcards
What is the purpose of Ethernet cables?
To connect devices to a wired network.
What is the connector type used for Ethernet cables?
RJ-45.
What is the maximum speed of a Cat5e cable?
1 Gbps.
What is the maximum speed of a Cat6 cable?
10 Gbps over short distances (up to 55m).
What is the difference between Cat6 and Cat6a cables?
Cat6a supports 10 Gbps over longer distances (up to 100m).
What is a crossover cable?
An Ethernet cable used to connect two devices directly without a switch.
What is the purpose of a patch cable?
To connect devices to a switch, router, or patch panel.
What is the difference between shielded and unshielded twisted pair (STP vs UTP)?
STP has shielding to reduce interference; UTP does not.
What is a plenum-rated cable?
A cable designed to be used in air ducts; it has a fire-resistant jacket.
What is the purpose of a keystone jack?
To terminate Ethernet cables in a wall plate or patch panel.
What is the primary purpose of fiber optic cables?
To transmit data as light signals for high-speed communication.
What are the two main types of fiber optic cables?
Single-mode and multimode.
What is the difference between single-mode and multimode fiber?
Single-mode is for long distances; multimode is for shorter distances.
What are common connectors for fiber optic cables?
LC, SC, and ST connectors.
What is the purpose of a fiber patch panel?
To organize and connect fiber optic cables in a central location.
What is the primary purpose of coaxial cables?
To transmit cable TV and internet signals.
What is the connector type used for coaxial cables?
F-connector.
What is the characteristic feature of a coaxial cable?
It has a single copper core and shielding to reduce interference.
What is the purpose of cable management?
To organize and protect cables for better performance and maintenance.
What is the importance of cable length in networking?
Exceeding the maximum length can result in signal loss or degradation.
What is the maximum length for Ethernet cables?
100 meters (328 feet).
What tool is used to terminate Ethernet cables?
A crimping tool.
What is the T568A and T568B standard?
Wiring standards for Ethernet cable connectors.
What is a punch-down tool used for?
To secure cables into patch panels or keystone jacks.
What is the purpose of cable testing?
To verify connectivity and ensure proper cable installation.
What tool is used to test the functionality of a network cable?
A cable tester or continuity tester.
What is a loopback adapter used for?
To test network interfaces and ensure connectivity.
What is the purpose of a USB cable?
To connect peripherals like keyboards and mice to computers.
What is the purpose of an HDMI cable?
To transmit high-definition video and audio signals.
What is the purpose of a Thunderbolt cable?
To provide high-speed data transfer, video output, and power delivery.
What is the purpose of a VGA cable?
To transmit analog video signals to monitors or projectors.
What is the difference between DisplayPort and HDMI?
DisplayPort supports higher resolutions and refresh rates than HDMI.
