The bitrate for an HD Blu-ray video is typically in the range of 20 mbps, standard-definition DVD is usually 6 mbps, high-quality web video often runs at about 2 mbps, and video for phones is typically given in the kilobits (kbps). For example, these are the targets we usually see for H.264 streaming:
That is, 1 KB = 1000 bytes, 1 MB = 1000 KB, 1 GB = 1000 MB. Thus, when an HDD reports that it has 80 GB, they mean it has 80,000,000,000 bytes available on it. Computer OSes don't use that.
