1. Network Media Guided Media ( transmit the data over a wire)
Twisted Pair Cable
Coaxial Cable
Fiber Optic
Unguided Media
( Transmits the data through air)
Satellite Transmission
Microwave Transmission

2. Advantages & Disadvantage of twisted Pair
It supports analog as well as digital transmission
Inexpensive transmission media
Disadvantages:
Noise prone
Transmission limits

3. Advantages & Disadvantage of Coaxial Cable
High transmission rate
Higher noise immunity
Disadvantages:
- comparatively costly
- security problem

4. Fiber Optics Advantages: - high transmission rate
- better noise immunity
- it can transmit the data at longer distance
- more data security
- high transmission quality

5. Fiber optic (disadvantages)
Expensive
Difficult to configure
Expensive maintenance

6. Advantages of Satellites
The advantages of satellite communication over terrestrial communication are:
The coverage area of a satellite greatly exceeds that of a terrestrial system.
Transmission cost of a satellite is independent of the distance from the center of the coverage area.
Satellite to Satellite communication is very precise.
Higher Bandwidths are available for use.

7. Basics: Disadvantages of Satellites
The disadvantages of satellite communication:
Launching satellites into orbit is costly.
Satellite bandwidth is gradually becoming used up.
There is a larger propagation delay in satellite communication than in terrestrial communication.

8. Advantages Fiber Optic
SPEED: Fiber optic networks operate at high speeds - up into the gigabits • BANDWIDTH: large carrying capacity • DISTANCE: Signals can be transmitted further without needing to be "refreshed" or strengthened. • RESISTANCE: Greater resistance to electromagnetic noise such as radios, motors or other nearby cables. • MAINTENANCE: Fiber optic cables costs much less to maintain.

9. Microwave Transmission
Microwave signals are also used to transmit the data & voice over the long distances through air without wires. In microwave transmission directional parabolic antennas are used to transmit the signals. Repeater are installed for sending and receiving signals along a line of sight.

10. Advantages & Disadvantages
It involves less costly technology as compared to satellite
Its transmission rate is high than twisted pair, coaxial and fiber optic cables
Disadvantages
Difficult to maintain repeaters
Signal noise
