Fiber optic cable.
185
# Pass and Advanced 985. How is the transmission made of the fiber optic cable?

186
# Pass and Advanced 986. What are the transmission rates of the fiber optic cable?
Approximately l billion (or giga) bits per second (Gbps), with speeds over 2 Gbps possible.
187
# Pass and Advanced 987. What are the major advantages of fiber optics over wire media?

# Pass and Advanced 988. Why is fiber optic cable immune to electrical interference of any kind?
It carries no electrical current.
189
# Pass and Advanced 989. What is one big disadvantage of fiber optic?
The tighter restrictions on how much the cable can be bent.

Network operating systems (NOS).
191
# Pass and Advanced 991. Why do application layer firewalls gain more insight into the data conversations that traverse an Internet link?
Because they examine packets and protocols at and above the transport layer, which controls the dialogue between communicating end nodes.
