What are the advantages of linked list over arrays?
# Linked lists do not need contiguous blocks of memory; extremely large data sets stored in an array might not be able to fit in memory. # Linked list storage does not need to be preallocated (again, due to arrays needing contiguous memory blocks). # Inserting or removing an element into a linked list requires one data update, inserting or removing an element into an array requires n (all elements after the modified index need to be shifted).
A single speed CD-ROM drive transfersdata at what rate?
150 KB/s.
Reference:
The first generation of "single-speed" CD-ROM drives were based on the design of audio CD drives, employing constant linear velocity (CLV) technology to spin a disc at the same speed as an audio CD which, with error correction, meant 150 KBps.

Do you know a software has DVD Converter DVD to Zune Video DVD to Zune Video all in one?
The easiest (and free) way to convert your DVD collection into zune format requires two programs. They are DVD decryptor and videora iPod converter. Both can be googled and they will be your first options. Once both are downloaded you will need to use the decryptor first to get all of the regional coding off the disk and turn it into vob format. Once that is finished locate the converted file and open videora, it will walk you through the process of converting the file. That takes about 20 minutes to complete and then you will be able to drag the completed file onto the zune and it will start to sync.
The process above is fussy, you could try this Daniusoft DVD Ripper . It can copy movies off DVDs and then convert them to Zune-friendly format at one time. Easy to use...

How it is related to data independence?
Hi,
Data Independence refers to the immunity of user application to make changes in the definition and organization of Data.
There are three types of Data Independence -
1. Logical Data Independence - The ability to change the logical (conceptual) schema without changing the External schema (User View) is called logical data independence.
2. Physical Data Independence - The ability to change the physical schema without changing the logical schema is called physical data independence.
3. View Data Independence - always independent,no effect.
You don't need a black box to split composite video. What you'd use is a video distribution amplifier with at least two outputs on it. (You can find used ones on Ebay and on the 'net).
The reason for the distribution amp is that when you split a composite video signal, it halves the output and consequently, the picture usually looks way too dark.
You're also going to have problems with copy guarding. That's the anti-theft scheme usually contained in the original DVD you're trying to copy. Of course, the exception would be a DVD that was mastered on a home computer or some similar piece of equipment. If you try to copy commercially produced DVD's, all you're going to end up doing is making a lot of coasters.
