Answer:
The wider channel bandwidth is efficient and good as it help in increasing the speed of the transmission. Due to the wider channel of the bandwidth it also lead to consuming less energy of the battery and make cost effective.
Due to the wider bandwidth, the number of clients can easily share and transfer the data in the channel and also make the transmission complete.
If the channel of the bandwidth is double then, the single transmission can easily carry more data. Hence, it also lead to double the speed of the transmission.

<h2>Why?</h2>
Optical disks are circular disks used as storage for binary data usually made of polycarbonate. The data is stored in the disc using a laser machine and accessed using a laser diode illuminating the data path in an optical disc drive.
CD: Compact Discs are the most basic optical disk used today, with only a capacity that goes from 0.7 GB (700 MB) to 0.84 GB (840 MB).
DVD: Digital Versatile Discs increase the storage up to 6 times compared with a CD, the capacity of DVDs optical disks goes from 4.7 GB (4700 MB) to about 17 GB(17000 MB).
UDO: Ultra Density Optical have high capacity storage that goes from 30 GB (30000 MB) to about 60 GB (6000 MB).
Have a nice day!
