Question

Bounded and Unbounded Data Transmission Explanation

IN YOUR OWN WORDS, PLEASE

• Describe what a bounded data transmission is
• Describe what an unbounded data transmission is
• Identify the advantages and disadvantages of the bounded and unbounded

Answer 1

1.

Bounded transmission means having connectivity between a source and destination using cables or wires. The signals have to travel through this channel i.e. physical media and this makes it limited to its expansion.

The types of Guided Transmission are as below:

1)     Twisted pair cable

2)    Co-axial Cable

3)     Fiber-optic

2.

Unguided or wireless media sends the data through air (or water), which is available to anyone who has a device capable of receiving them. Types of unguided/ unbounded media are:

• Radio Transmission
• MicroWave Transmission

3.

• Bounded Data Transmission

Advantages:

1.Higher bandwidth

2.Immunity to electromagnetic interference

3.Resistance to corrosive materials

4.Lightweight

5.Less signal attenuation.

Disadvantages:

1.More difficult installation

2.Very costly

3.Bending is not easy

4.Limited in distance

• Unbounded Data Transmission

Advantages:
1.radio wave transmission offers mobility.
2.It offers ease of communication over difficult terrains.
3.It offers freedom from land acquisition rights that are required for laying,repairing the cables.
Disadvantages:
1.radio wave communication is an insecure communication.
2.Radio wave propagation is susceptible to weather effects like rain,thunder and storm etc.
