1 @ 100 meters
Cat 6a has a defined speed of __GB/s.
10 @ 100 meters
Cat 7 has a defined speed of __GB/s.
10 @ 100 meters
What is the difference between Cat 6a and Cat 7?
Cat 6a is unshielded whereas Cat 7 is shielded.
What does UTP and STP stand for?
Ushielded Twisted Pair
Shielded Twisted Pair
Name a hybrid topology.
Star-bus
Meshed
Partially-meshed
Name a topology.
Bus
Token Ring
Star
What is the measurement for electrical resistance?
Ohms
Define RG Rating
RG ratings define the thickness of cabling and resistance.
Name the (3) fire protection ratings.
Plenum
Riser
PVC or non-plenum
IEEE Standards are…
… a computing-standards, governing body that sets regulations for connectors.
What does Co-Axial (coaxial) mean?
Coaxial implies it contains two conductors: inner copper conductor and a conducting layer that sheathes the copper. I.e., common axis
Describe a BNC connector.
Rotating locking mechanism that does not use any threading.
Describe an F-Type connector.
Only on cords used on modems.
Describe an ST connector.
Earliest type of connector and resembles the BNC connector; straight-tipped and rounded twist-connector.
Describe an SC connector.
Equally just as old as ST connectors; square-shaped and just punch in and out of the connection.
Describe an FC connector.
Looks identical to ST connectors; straight-tipped and rounded screw-connector.
Describe an LC connector.
Duplex connectors that look like two SC connectors glued together for one connection instead of two.
Describe a MT-RJ connector.
Looks completely different from all other connectors; this connector masks the two cables to make it look like there’s only one cable.
Define these three fiber-tip styles:
PC
UPC
APC
PC - physical contact; rounded-square end.
UPC - ultra physical contact; more rounded than square end.
APC - angled physical contact; a 45 degree cut that creates a fine point end.
Name and describe the difference between UTP and STP.
Unshielded Twisted Pair; typically four pairs of twisted conductor wire which varies in category based on number of twists per inch (i.e., cat3 vs cat5 vs cat6).
Shielded Twisted Pair; the same as UTP but contains shielding that protects from environmental interference, typically coming from nearby electrical devices.
What is a serial port?
Oldest I/O connection in the world of computers and uses RS-232 communication language.
What is a parallel port?
Aka., IEEE 1284; used primarily for printers.
Which type of port (serial or parallel) is the oldest I/O connection and uses RS-232 communication language?
Serial port
Which type of port (serial or parallel) is extremely outdated and was used for printers?
Parallel port
I need a legacy cable to connect my laptop to my routers’ serial port. What kind of cable would I use?
A Yost cable or Rollover cable.
Which RG rating has a resistance of 50 ohms?
RG-58
Which RG ratings have a resistance of 75 ohms?
RG-59
RG-6
Which RG rating has the thickest gauge wire?
RG-6
What color(s) indicate multi-mode fiber optic?
Mainly orange, sometimes aqua.
What color(s) indicate single-mode fiber optic?
Yellow
True/False: single-mode fiber optic uses lasers and is designed to go farther than multi-mode fiber.
True
