Question

Give me the matter to include in a chart of guided and unguided media. Please remember it is a chart.

Answer 1

You can distiguish between guided and unguided media and tell about the advantages and disadvantages for the same and paste some pictures...... You can add few points like the following:
For guided:
1. Optical signals pass through a solid medium means it uses wires.
2. The signals is guided by the size, shape and length of the wire.
3. E.g.- Copper Un-shielded Twisted Pair, etc.

For Unguided:
1. Optical signals doesn't pass through a solid medium means it is wireless.
2. Frequency spectrum use the electromagnetic signals.
3. E.g.- LAN, WAN, MAN, PAN, etc.

Answer 2

Answer:

here is ur ans

The computer and other communicating devices represent data in the form of signals. The signals transmit between communicating devices in the form of electromagnetic energy, and hence the signals are called electromagnetic signals. Electromagnetic signals are the combination of electric and magnetic fields that vibrates in relation to each other. The electromagnetic signals can travel through various transmission media. The transmission media is broadly classified into two categories that are guided and unguidedmedia.

The basic difference between guided and unguided media is that in the guided media, the signal travels through a physical medium whereas, in unguided media, the signal travel through the air. There are some more differences between guided and unguided media which I have discussed with the help of comparison chart shown below....
