Broadband vs Baseband

1. Why does broadband have higher data rates than baseband?

Broadband achieves higher data rates than baseband due to its ability to perform frequency division multiplexing(FDM).Frequency division multiplexing allows multiple signals to transmit simultaneously over a wide range of frequency, this helps in optimizing the use of the entire available bandwidth. In contrast, baseband use their entire bandwidth for a single signal which limit’s their overall data transmission capacity.

2. Explain the concept of modulation in terms of baseband and broadband?

Baseband and broadband both use modulation as a key technique to efficiently transmit information in networks. In broadband modulation is the process where information is encoded onto a carrier signal at a higher frequency known as passband modulation.In baseband modulation directly varies the amplitude ,phase or frequency of the original signal.

3. How does technologies like broadband and baseband affect the network architecture?

Broadband utilize multiple channels ,supporting diverse data transmission and complex infrastructure.It is suited for long distance as it uses advance multiplexing techniques and is suited for high data rate applications.Baseband in contract, support in dedicating the entire bandwidth to a single channel which result in simple infrastructure which is used for shorter distance.It is suitable for lower data rate needs.

4. State a example of broadband and baseband.

Example of baseband technologies include:Digital Subscriber Line(DSL) .DLS is used to access internet in residential areas.It utilize telephone lines to deliver high speed internet.

Example of baseband include:Ethernet. It is a baseband technology that enables digital communication between devices through a direct wire without modulation.

5. What is the purpose of the outer metallic shielding in coaxial cable?

The outer shielding in a coaxial cable server as a crucial part of the coaxial cabe.It acts as a shield against electromagnetic interface(EMI) and radiofrequency interface(RFI).It prevents the leakage of the signals being transmitted through the cable and also prevents external signals from interfering with the signals being transmitted through the coaxial cable.

Coaxial Cable is the fundamental concept in networking and communication due to its ability to serve as a transmission medium for a wide range of signals. Within the domain of coaxial cable, there are two categories named: Broadband and Baseband. These distinctions are important in determining the type of transmission and the application related to it. Baseband coaxial cables are known for their ability to transfer data over long distances and also their design which allows them to carry multiple signals simultaneously. On the other hand, Basebands are coaxial cables that can only transmit data at a short distance and can carry a single digital signal. Baseband and Broadband communication are very efficient approaches to utilizing coaxial cables for transferring data.
