network

application

data-link

session

Question 2. Frames from one LAN can be transmitted to another LAN via the device

router

bridge

repeater

modem

Question 3. The slowest transmission speeds are those of

twisted-pair wire

coaxial cable

fiber-optic cable

microwaves

Question 4. The Internet Control Message Protocol (ICMP)

allows gateways to send error a control messages to other gateways or hosts

provides communication between the Internet Protocol Software on one machine and the Internet Protocol Software on another

only reports error conditions to the original source, the source must relate errors to individual application programs and take action to correct the problem

All of the above

Question 7. 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 8. 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.

modem

protocols

gateway

multiplexer
