UNITS FOR MEASURING INFORMATION

To measure the amount of information stored in a memorv device: 1 bit = 1b = binary digit = is the mĂ­nimum amount of information in computer science or digital electronics and it is represented using the lower case letter b. 1 byte = 1B = is equal to 8 bit and is represented using the upper case letter B.

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
