1 Kilobyte = 1KB = 1024 bytes 1 Megabyte = 1MB = 1024 KB 1 Gigabyte = 1GB = 1024 MB 1 Terabyte = 1TB = 1024 GB 1 Petabyte = 1PB = 1024 TB To measure the speed of information transfer (sendinq and receivinq): bps = bits / second = bits / s = bits per second Bps = bytes / second = bytes per second Kbps = Kilobits / second Mbps = Megabits / second
