CD-RW (Compact Disk Re-Writable)
what CD that allows you to read and write
You can't. You must have a drive with writing capabilities to write to a CD.
That means it is a CD you can WRite to.
Twice a year.
CD-R
CD-R or CD-RW , BUT CD-R is better
CD+r means write once, read many. This means that you can only write data to the CD once, after that it will be on there forever and you can always get to it.
WINDOWS(whidout Nero)copy data to CD/DV-RW with just simple copy and pasteinsert the CD/DVDright click properties->recordingenable CD-recording on this driverselect write speed( i sugest 4~32x)ok then right click again and click on write files to CD
Burning of a CD means that you laser write data onto the silver surface of the CD.
Not necessarily. You can have a CD/DVD reading drive that does not write.
It depends on the CD's format, how it was burned, and whether the session is still open or not. If it is a CD-RW(Read/Write) you can erase these and re-write data on them. If you are trying to erase a store bought CD or a CD-R or CD+R you are out of luck, once these are burned they are done.
A CD-RW drive is able to Read CDs, VCDs, and write CD-R and CD-RW.
