The Giga Bytes are the unit of measurement so you can't really say how much it holds. It is like asking how long one centimeter. If you are talking about songs than it depends how long the songs are.
About 4 gb
CDs cannot hold 4gb but a single layer DVDR can. CDs cannot hold 4gb but a single layer DVDR can.
NOT A LOT i recommend 32 GB
depends on the motherboard, but average would be 4gb.
A 4GB memory card will hold about two hours of 720p recording. One gigabyte will hold about 30 minutes of this type of recording.
2 times as much as 4gb which is 2 times as much as 2gb
they usually hold up to around 4000 songs that's pretty good
4GB Holds up to 1,000 songs Holds up to 3,500 photos Holds up to 4 hours video
2GB- 500 songs 4GB-1000 songs 5GB-1500 songs 8GB-2000 songs
doe the sylvania hold more songs
1GB will hold about 1-1 1/2 hours of video, so a 4GB iPod can hold around 5-6 hours. Although, I cannot think of a 4GB iPod that will support video playback. There is only the 8GB iPod Nano that plays video.
It depends on the size of the songs. However, 4gb MP3 players can generally hold approximately 1000 songs.
