Disclaimer: I don't know much about this. I am just
elaborating my understanding in a better way, after reading
the explanation from Radhar, credits to him/her.
Say I( for Information;-) needs to travel from Point T
(transmitter) to Point R (Receiver).
There can be several medium through which I can travel.
1. Air
2. Water
3. Road
4. Rail
There are several type of Carriers vehicle I can choose to
travel in the Medium.
1. By Train
2. By Bus
3. By Aircraft
4. By a Boat
5. By a Bicycle/Walk
Now the question is how to go? What carrier to choose?
1. How fast I have to travel. ( Certain carriers are faster
than others )
2. How far I have to travel. ( Certain carriers makes I
less fatigued (Information loss))
3. How much does it cost me. ( Carriers with more bandwidth
are generally less costly )
4. Availability of the Carrier (Bandwidth, clearly ships
have more space than buses on trains, but are slower)
5. What medium do want to travel ( Certain carriers are
better suited to travel in a particular medium than others)
Now you guys do rest of math based on this analogy.
