A memory is different than storage. If you store stuff in a memory you can use it but if you store something in the storage it gets saved in a hard drive. Dynamics means it changes. The only code the computer understands is binary. Do not put a CD rom in the microwave. There are three parts on a CD rom, the label, the shiny reflection metal surface, and the other pieces of plastic. The most delicate place on a disc is the top part, one should not write on it. CD's have millions of pits in it. They are called bumps. If a laser sees a pit it the CD will work if it doesn't work. 1 megabyte is a million bits. 700 million X 8= 5 billion little pits on a disc or the shiny spots. A DVD has 1 bite which equals to 8 bits. There is a printed circut card on the back. If there is a scratch on the disc the laser will not be able to read the binary code. The laser light bounces off the shiny part and if there is a pit it counts it as 1. Hard drives and floppy discs are not stored optically. Hard Drives are hard and floppy discs are floppy.
