If a cd-r holds 700mb of information and you copy a file that is only 100mb of information can you continue to copy to a cd-r until all 700mb have been used?
It depends. If you do an "all at once" you will only be able to put the 100mb on. However, if you do a mulitsession burn, you will be able to keep filling up the disk until it is full. The downside to this is that not all computers can read these disks, so it is generally better to do an "all at once".
I agree that DVD drives hold much more data than their CD cousins. The CD can hold up to only 700 megabytes, which is small by modern standards while a single-layer DVD can hold up to 4.7 gigabytes and a dual-layer can hold up to 8.5 gigabytes. So, in regard to space, the DVD definitely is the king. Now as to the advantage of the discs with the -RW designation, whether it is the CD-RW…
What temporarily holds programs and data while the computer is on and allows the computer to access the information randomly?
What is activation record and activation tree How these are related with run time storage organization?
What is a special database that holds key information about your system including the device drivers?
The memory is a storage area that holds information. The processor processes, computes, and manipulates the information. Nowadays, the CPU does contain some information, but it is used for storing the most used information to make it easier for the CPU to access it. The RAM holds the programs while they are running, but the CPU is what runs the programs.

Compact Disks Instead of electromagnetism, CDs use pits (microscopic indentations) andlands (flat surfaces) to store information much the same way hard disks use magnetic and non-magnetic storage. Inside the CD-ROM is a laser that reflects light off of the surface of the disk to an electric eye. The pattern of reflected light (pit) and no reflected light (land) creates a code that represents data. CDs usually store about 700MB. A DVD or Digital Video Disk…
