Question

Why we used "of" here?
In this sentence, "how many gigs of music can it hold?"
-- Why we use "of " here? How can I understand it?
-- Does the "gigs" mean "gigabit"?

Answer

Yes, gigs is referring to the amount of data that the device holds as in gigabytes.  The of is used to imply that the gigabytes is a measure for the amount of music a device may hold.  Other examples that follow this pattern are: 
- How many cups of coffee does that pot hold?
- How many tablespoons or grams of sugar does the recipe call for?
The word of is used to show a relationship between a part and a whole or to define which portion of a measure is being define.  
The gigabytes is the part of the whole music or the cups is a part of the whole pot.
  
I hope this helps. :)
