Encoding
Encoding converts the stream of bits into a format recognizable by the next device in the network path.
Example: Manchester, 4B/5B, 8B/10B
Signaling:
The signaling method is how the bit values, “1” and “0” are represented on the physical medium.
The method of signaling will vary based on the type of medium being used.
Bandwidth
• Bandwidth is the capacity at which a medium can carry data.
• Digital bandwidth measures the amount of data that can flow from one place to another in a given amount of time; how many bits can be transmitted in a second.
Latency
Throughput
Goodput
• The measure of usable data transferred over a given period of time•
Goodput = Throughput - traffic overhead
