Welcome to Networking Quiz, Entry Level !!

Question 1. The slowest transmission speeds are those of

twisted-pair wire

coaxial cable

fiber-optic cable


Question 2. 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 3. The geostationary satellite used for communication systems

rotates with the earth

remains stationary relative to the earth

is positioned over equator

all of the above

Question 4. 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.

Question 5. contention is ?

One or more conductors that serve as a common connection for a related group of devices

a continuous frequency capable of being modulated or impressed with a second signal

the condition when two or more stations attempt to use the same channel at the same time

a collection of interconnected functional units that provides a data communications service among stations attached to the network

Question 6. 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 7. 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 8. What device separates a single network into two segments but lets the two segments appear as one to higher protocols?





Question 9. The communication mode that supports two-way traffic but only one direction at a time is





Question 10. Which of the following is used for modulation and demodulation?
