Cables

Question 1

RG 59

Answer 1

Coaxial cable with 75 ohm resistance, not super robust, has an F-Type connector, still used

Question 2

F-type connector

Answer 2

is threaded, only seen with cable modems, and cable tv

Question 3

RG 6

Answer 3

Coaxial cable with 75 ohm resistance, widely used with cable modems, thicker and more advanced than RG 59

Question 4

RG 58

Answer 4

Coaxial cable with a 50 ohm resistance, rarely used any more, has a BNC connector

Used for Thin Ethernet networks segments

10GBaseEW - same but works on Sonet

Question 17

RG 8

Answer 17

Commonly used for cable TV and digital and video signals. Used for Thick Ethernet network segments Uses the N-connector

Question 18

Thick Ethernet

Answer 18

Thick Ethernet was the first commercially available form of cabling supported by Ethernet. It is technically known as 10-BASE-5. Here, 10 is the maximum throughput, i.e. 10 Mbps, BASE denoted use of baseband transmission, and 5 refers to the maximum segment length of 500 metres (1,600 ft). This type of cabling allows 100 stations to be connected to it by vampire taps.

Question 19

Thin Ethernet

Answer 19

Thin Ethernet, popularly known as cheapernet or thinnet, is among the family of Ethernet standards that uses thinner coaxial cable as a transmission media. It is technically known as 10-BASE-2.

Here, 10 is the maximum throughput, i.e. 10 Mbps, BASE denoted use of baseband transmission, and 2 refers to the maximum segment length of about 200 metres (precisely 185 metres). This type of cabling allows a maximum of 30 stations to be connected to it by BNC connectors with 50 centimetres minimum gap between subsequent stations.

Question 20

Fiber-Optic connector types

Answer 20

Straight tip (ST)
Subscriber connector (SC)
Mechanical transfer-registered jack (MTRJ)
Fiber local connector (LC)
