What does GB mean?
GB is short for ‘Gigabyte’, which is a chunk of data. Everything which is sent over the internet is made up of chunks of data, and that’s whether it’s a web page, an email, a music track, video clip or movie. • If 8 Bits of data = 1 Byte, then • 1024 bytes of data = 1 Kilobyte (KB), then • 1024 KB of data = 1 Megabyte (MB), then • 1024 MB of data = 1 Gigabyte (GB) Of course, each involves a different amount of data – the average email (without attachments) is around 4 KB, whereas digital photographs are around 1 MB. An MPEG3 music file compressed to playback at 128Kbit/s is around 3 to 4MB.
