2. What is the difference between Celeron S,M, and D? (if those are the right letters.)
I dont whether there is a "Celeron S".
"Celeron M" is the mobile-optimized version of the noramal Celeron, typically used in Laptops. As laptops need to be run on batteries the "Celeron M" uses less power and generates less heat than the noram Celeron.
"Celeron D" is the dual-core variant of Celeron. What this means is there are two processors running on a single chip. Dual-core is a new technology. Dual-core helps to increase parallelism in computing.
4. How is Unix different from Linux?
Linux has a GUI like windows. Unix has no GUI its more like DOS with lots of other advanced features.
5. How is Unix when compared to Windows XP?
You can't actaully comapare the two. UNIX is really old, it has no GUI.
A better comparsion would be "Linux vs. Windows".
9. Are DVDs still easier to damage than CDs, or has there been some improvements?
DVD and CD both are physically made of the same plastic. So, u can't say DVD get damaged easily. But u will be loosing more data, if it does.
Without any physical damage, over long course of time; yes, a DVD will wear-n-tear faster than a CD, because of the fact that DVD needs a higher power laser (smaller wavelenght of the laser).
Hopefully with the coming of Blu-Ray disks, these problems will be resolved as Sony and its partners have come out with a new-material to protect the read-able side(s) of a disc.
