Question 2:

Look at the table below and put the LETTER of the correct component with the correct description. Write the layers NUMBER or NUMBERS (1-7) where the component is found on the OSI model in the box on the right: (7 Points)

Component number	Network Component		Network Component	Functions	OSI Layers Number
	Network Adapter		.	Connects computers in a network; receives a packet from a sending computer and transmits it only to its destination.	.
	Modem (0.5 Points)		.	Connects computers in a network; receives a packet from a sending computer and transmits it to all other computers.	.
	Repeater (0.5 Points)		.	Connects networks with different Layer 2 protocols; divides a network into several segments to filter traffic.	.
	Bridge		.	Connects computers in a wireless network; connects the wireless network to wired networks; connects it to the Internet.	.
	Hub (0.5 Points)		.	Puts a message (baseband signal) on a carrier for efficient transmission; takes the baseband signal from the carrier.	.
	Switch		.	Converts a computer message into electrical/digital signals for transmission across a network.	.
	Access Point (0.5 Points)		.	Connects two totally different networks; translates one signaling/protocol into another.	.
	Router		.	Receives signal, amplifies it, and then retransmits it.	.
	Gateway		.	Forwards a packet to its destination by examining the packet destination network address.	.
