Chapter 3 Hardware Key Terms Flashcards
Ethernet
A set of standards for network communication in local area networks
CAT5e
Category 5e TP cable. Supports Gigabit Ethernet (10/100/1000Mbps)
CAT6
Category 6 TP cable. Supports 10G Ethernet (10/100/1000/10000Mbps)
and reduces crosstalk for more reliable connections at Gigabit speeds.
plenum
air space in a building, such as HVAC ductwork or a suspended ceiling. Plenum cable, which produces very little smoke when burned, is required when a plenum is being used for cabling
Unshielded twisted pair (UTP)
Ethernet cables with 4 pairs of twisted wires inside
a sheath
Shielded twisted pair (STP)
Ethernet cable with added shielding to protect against
electromagnetic interference
568B
A TP wiring standard that uses the following wires from pins 1 to 8:
orange stripe, orange, green stripe, blue, blue stripe, green, brown stripe,
brown
568A
A TP wiring standard that uses the following wires from pins 1 to 8:
green stripe, green, orange stripe, blue, blue stripe, orange, brown stripe, brown
fiber-optic cabling
Network cable that uses glass fibers to transmit photons to
carry data
coaxial cabling
A type of cable that consists of a solid center copper core, insulation, a metal braided jacket for grounding, and a vinyl or plastic outer jacket. Commonly used for cable TV, cable Internet, and satellite Internet
Bayonet Neill-Concelman or British Naval Connector (BNC) connector
a connector used to attach legacy Ethernet 10Base2 coax cable.
F connector
A connector used for cable, satellite, and fixed wireless Internet and
TV service. Can be crimped or attached via compression to the coaxial cable
Video Graphics Array (VGA)
the first popular analog video standard and the basis
for all current video cards
Super Video Graphics Array or Super VGA (SVGA)
800×600 VGA resolution or
any VGA display setting that uses more than 16 colors or a higher resolution than
640×480.
High-Definition Multimedia Interface (HDMI)
A compact audio/video interface for transmitting uncompressed digital data.
mini-HDMI
A type of cable/connector used by high-performance video cards and
some tablets
DisplayPort
A cable and port primarily used to transmit video that can also send
audio and USB signals. Designed as a replacement for VGA and DVI
Lightning
The proprietary, reversible Apple iOS sync/charging USB 2.0 connector. Used on older iOS devices.
Thunderbolt
An Intel-developed ultra-high-speed I/O interface that is available
in three versions: 10Gbps (Thunderbolt 1), 20Gbps (Thunderbolt 2), and 40Gbps
(Thunderbolt 3). Used widely by Apple and by some high-performance PCs
USB
Universal Serial Bus; a high-speed replacement for older I/O ports. Several
generations of USB have been implemented, the latest being USB 3.1 Gen 2.
USB-C
The newest reversible USB connector; should replace other USB types
USB 2.0
Universal Serial Bus version 2; a version of USB with peak speed of
480Mbps that is compatible with USB 1
USB 3.1 Gen 1
Universal Serial Bus version 3.1 Generation 1; the same as USB
3.0
USB 3.1 Gen 2
Universal Serial Bus version 3.1 Generation 2; a version of USB
that runs at 10Gbps and is compatible with USB 3.0, 2.0, and 1.1 devices
