Question 3. A remote batch-processing operation in which data is solely input to a central computer would require a:

telegraph line

simplex lines

mixedband channel

none of the above

Question 4. When you ping the loopback address, a packet is sent where?

on the network

Down through the layers of the IP architecture and then up the layers again

Across the wire

through the loopback dongle

Question 5. What frequency range is used for FM radio transmission?

Very Low Frequency : 3 kHz to 30 kHz

Low Frequency : 30 kHz to 300 kHz

High Frequency : 3 MHz to 30 MHz

Very High Frequency : 30 MHz to 300 MHz

Question 6. Which of the following is not a reason to use fiber-optic cables for point to point data transmission?

Need to assure data security.

Avoidance of ground loops.

Data-transfer rates too low to use metal cables.

Elimination of spark hazards.

Question 7. Which of the following is used for modulation and demodulation?





Question 8. A distributed network configuration in which all data/information pass through a central computer is

bus network

star network

ring network

point-to-point network

Question 9. Frames from one LAN can be transmitted to another LAN via the device





Question 10. What makes optical fibers immune to EMI?

They transmit signals in as light rather than electric current.

They are too small for magnetic fields to introduce current in them.

Magnetic fields cannot penetrate the glass of the fiber.

They are readily sheilded by outer conductors in cable.
