Volume fragmentation is where the partition volume is physically split across the drive into variable pieces. This is common on HFS and some other filesystems that do not need to be sequential or single-piece, and virtual filesystems.
Data fragmentation is when a file or data portion is physically split across a volume, rather than being in a single sequential piece. This is also called 'fragmentation' and can usually be remedied with a 'defragmenter'. It is usually an undesireable state, as it requires longer to load a fragmented file.
The cambelt connects the camshaft to the crankshaft, the belt drives the camshaft and keeps it in the correct timing (when the valves open/close in relation to the crankshaft angle.)
There is not a difference between IBM lto5 tape drives 3588 f5a and hp lto5 tape drives eh957b. They are both a software tape.
If you mean between hard drives and ssd's (solid state drives), then you need to read the wikipedia page on Solid State Drives, it has a comparison of the two technologies.
There's no difference other than what's on them.

when you rent a car, you or an adult drives it but in a taxi a taxi man drives it, a complete stranger! :)
a vector drive is vertical, a scalar is horizontal.
A truck drives on the road, and a train is on a train track.
Historically, hda was used for IDE drives and SDA was used for SCSI drives. Today, regardless of physical interface, all drives are treated as SCSI devices.
It depends on the type of drive. Fragmentation really does nothing to SSD drives since all storage cells are the same and can be accessed just as fast. Defragmenting an SSD drive only adds to the wear and tear and provides no discernible benefit. On mechanical hard drives, it can slow the drive and possibly lead to increased wear. However, that is not a reason to obsessively defrag, since that could also lead to increased wear and tear, and the time you spend defragmenting could take longer than the time you spend with the fragmentation. If you want to know what fragmentation is, it is simply having files chopped up into multiple chunks and stored that way. On SSD drives, there is no consequence to this. Mechanical drives would have to seek to find each chunk, resulting in more movement of the heads and slower access to the file.
Without more information, there is not enough to conclude that there even is a difference.
The difference is that a chauffeur is a driver always in a white uniform and is more experinced, while a driver is paid less and drives in ordinary clothes.
