- ____________________________ occurs when the fiber-optic media are not precisely aligned to one another when joined.
- What is the purpose of cladding in fiber-optic cables?
- What happens if the CSMA process fails and two devices transmit at the same time, creating a data collision?
- Which Wi-Fi standard operates in the 2.4-GHz frequency band and offers speeds of up to 54 Mbps?
- In which type of industry is fiber optic being used to provide always-on broadband services to homes and small businesses?
- The more dispersion there is in a fiber-optic cable, the less the loss in signal strength and the greater the effective distance of the signal over the fiber.
The ___________________ topology is the most common physical LAN topology.
- Which of the following items do not comprise the physical components addressed in physical layer standards?
- A wireless device will experience degradation in performance based on its distance to a wireless access point.
- In _______________________________, all nodes compete for the use of the medium but have a plan if there are collisions.
- UTP cable consists of _______ pairs of color-coded wires that have been twisted together and then encased in a flexible plastic sheath that protects them from minor physical damage.

- Coaxial cable was traditionally used in cable television and was capable of transmitting in two directions.
Practical bandwidth of a network is determined by a combination of which factors?
- ___________________________ permits the transmission of data over longer distances and at higher bandwidths (data rates) than any other networking media.
- Controlled access is also known as ______.
- A(n) _______________________ transmission exists when data signals are transmitted without an associated clock signal. (CSIS 330 quiz 3)
- According to the textbook, throughput usually does not match the specified bandwidth in physical layer implementations.
- ___________________________ is throughput minus traffic overhead for establishing sessions, acknowledgements, and encapsulation.
- It is the _______________ that influences the type of network framing and Media Access Control used.
- _________________________ is a transmission technique in which the amplitude of the carrier varies in accordance with the signal.
