...A Compact Disc (also known as a CD) is an optical disc used to store digital data. It was originally developed to store sound recordings exclusively, but later it also allowed the preservation of other types of data. Audio CDs have been commercially available since October 1982. In 2009, they remain the standard physical storage medium for audio. Read full entry

How to calculate the number of Can anyone help me with
this...
A compact disk has a
resolution of 16 bits and a
sampling frequency of 40 kHz.
If the recording lasts for 30
minutes, how many bits dose
the disc contain?
Thanks a million to anyone who
can help me.

How do I transfer files to I've gotten a lot of picture
files and folders in my
computer, and they're taking
up a lot of memory, too much
to store on the internet, I
want to put them on a compact
disc. I tried drag and drop,
like I would with USB, it
didn't work. How would I be
able to transfer my picture
files to disc? I got the
correct disc and everything, I
just want to store my photos
on my disc. Any idea on how to
do that?
What would I use in the first
place to do the transfers?
Thanks in advance.

Drag and drop should work but that only queues up the files for burning to the CD. It doesn't actually burn until you do the second step. Also you can select the files by highlighting them, right-click and Send To... D: (assuming D: is your burner drive) Once they are queued up you have to right-click on the D: drive and select 'Write these files to CD' which starts the burn process. An easier way to manage pictures is to use the free Picasa program from Google. Picasa catalogs all your photos on your system and making a backup or gift CD is as easy as a couple of clicks. I manage over 80,000 pictures on my system with Picasa. Links: Copy your files to a CD - Microsoft.com Download free Picasa |

Sampling frequency of 40 kHz means 40 000 times per second. I am not sure exactly what the "resolution of 16 bits" means in respect of sound recording, but I will assume that it means that it reads 16 bits in each sample, so that the number of bits read per second is 40 000 x 16 = 640 000 bits, or 64 x 10^4. If the recording lasts for 30 minutes, that is 30 x 60 = 1800 seconds, then at a rate of 64 x 10^4 bits per second, the disc will have to contain 1800 x 64 x 10^4 bits, that is, 1152 x 10^6 bits. |
