What is Baseband signaling? |
|
Definition
-The data signal is transmitted directly over the transmission medium
-uses the entire bandwidth of the transmission medium |
|

Ethernet Fundamentals
What is Broadband signaling? |
|
Definition
-In broadband signaling, the data signal is no longer placed directly on the transmission medium
Radio broadcasts and cable TV use broadband signaling

Ethernet and the OSI model
Ethernet operates in two areas of the OSI model |
|
Definition
- Lower half of the data link layer, which is known as the MAC sublayer
- The physical layer

Ethernet and the OSI model
How are layers 1 and 2 independent of each other? |
|
Definition
| Data link sublayers contribute significantly to technological compatibility and computer communications
The MAC sublayer is concerned with the physical components that will be used to communicate the information
The Logical Link Control (LLC) sublayer remains relatively independent of the physical equipment that will be used for the communication process

Definition
Logical Link Control Sublayer
----------------
802.3 Media Access Control(ler)
----------------
Physical Signaling sublayer
-------
Physical Medium
Both Signaling and Medium deal directly with and are the 10Base-T, 1000Base-T, etc standards
802.3 Ethernet stops at the MAC Data-link sub-layer
