C
Correct answer
Explanation
The most common type of connector used with coaxial cables is the Bayone-Neill-Concelman (BNC) connector. Different types of adapters are available for BNC connectors, including a T-connector, barrel connector and terminator. Connectors on the cable are the weakest points in any network.

-
All of the above
A
Correct answer
Explanation
Coaxial cabling has a single copper conductor at its centre. A plastic layer provides insulation between the centre conductor and a braided metal shield. The metal shield helps to block any outside interference, therefore we use it in CABLE TV. Thin coaxial cable is known as thinnet (10base2). The most common ones are RG 59(Coaxial cable) and a low loss cable is RG 6, both are 72 ohm for TV sets and antennas.

collision
-
continuous time
-
slotted time
-
either continuous time or slotted time
-
none of these
A
Correct answer

If two frames are transmitted simultaneously. They overlap in time and the resulting signal is distorted or garbled. This event or situation is called a collision.
-
15 Mbps
-
17 Mbps
-
20 Mbps
-
25 Mbps
C
Correct answer
Explanation
By using Nyquist's Theorem,
C = 2B log2M
= 2 x 5 x 106 x log24
= 20 Mbps
-
Simplex
-
Full duplex
-
Half duplex
-
All of the above
C
Correct answer
Explanation
In half duplex mode, each station can transmit and receive data but not at the same time. When one device is sending the data, the other can only receive, and vice versa. Radio is the example of half duplex, where at a time one can talk and other can listen, and vice versa.
