Q

What does Co-Axial (coaxial) mean?

A

Coaxial implies it contains two conductors: inner copper conductor and a conducting layer that sheathes the copper. I.e., common axis

16
Q

Describe an F-Type connector.

A

Only on cords used on modems.

17
Q

Describe an ST connector.

A

Earliest type of connector and resembles the BNC connector; straight-tipped and rounded twist-connector.

18
Q

Describe an SC connector.

A

Equally just as old as ST connectors; square-shaped and just punch in and out of the connection.

19
Q

Describe an FC connector.

A

Looks identical to ST connectors; straight-tipped and rounded screw-connector.

20
Q

Describe an LC connector.

A

Duplex connectors that look like two SC connectors glued together for one connection instead of two.

21
Q

Describe a MT-RJ connector.

A

Looks completely different from all other connectors; this connector masks the two cables to make it look like there’s only one cable.

22
Q

Define these three fiber-tip styles:
PC
UPC
APC

A

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.

23
Q

Name and describe the difference between UTP and STP.

A

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.

24
Q

What is a serial port?

A

Oldest I/O connection in the world of computers and uses RS-232 communication language.

25
Q

What is a parallel port?

A

Aka., IEEE 1284; used primarily for printers.

26
Q

Which type of port (serial or parallel) is the oldest I/O connection and uses RS-232 communication language?

A

Serial port

27
Q

Which type of port (serial or parallel) is extremely outdated and was used for printers?

A

Parallel port

28
Q

I need a legacy cable to connect my laptop to my routers’ serial port. What kind of cable would I use?

A

A Yost cable or Rollover cable.

29
Q

Which RG rating has a resistance of 50 ohms?

A

RG-58

30
Q

Which RG ratings have a resistance of 75 ohms?

A

RG-59

RG-6

31
Q

Which RG rating has the thickest gauge wire?

A

RG-6

32
Q

What color(s) indicate multi-mode fiber optic?

A

Mainly orange, sometimes aqua.

33
Q

What color(s) indicate single-mode fiber optic?

A

Yellow

34
Q

True/False: single-mode fiber optic uses lasers and is designed to go farther than multi-mode fiber.

A

True
