Multiplexing is a technology used to combine multiple protocols together.
false
What are the two main types of multiplexing?
(Format: xx and xx)
analog and digital
Which multiplexing method uses various frequencies to combine streams of data?
FDM (frequency division multiplexing)
What WAN protocol consists of Balanced and Unbalanced configurations?
HDLC (High-level data link control)
In which WAN circuit is the transmission path cleared prior to data being sent, and upon completion, the path is destroyed/no longer used?
circuit switching
In a ___ ___ circuit, there is a central switch in a MAN that all data goes through.
metro ethernet
Which of the following is a WAN Circuit that uses fragmentation to deliver traffic?
packet switching
______ is a WAN protocol that is seen in use for Point-to-Point and Point-to-Multipoint networks
HDLC (high-level data link control)
A ___ ___ circuit uses fragmentation, which describes data that is broken up into smaller packets, and can be sent down different routes to the same destination.
packet switching
What protocol provides a standard method for transporting multiprotocol data and authentication between two directly connected nodes?
PPP
What service was made in order to speed up the transmission of packets, namely by not relying on network protocols to perform encapsulation for it?
frame relay
____ protocol has three layers of operation with the most important being the Data Link Layer.
x.25
In PPP, the ___ component has control over the state of the transmission link
Link Control Procotol
_____ is a newer, and more expensive, way to send packets. It has pre-set routes which are called “Labels”.
MPLS (multi-protocol label switching)
What protocol discussed utilizes congestion notifications for traffic?
frame relay
