The Memory Units•1 b – 1 bit•1 Kb = 1024 (210) b – 1 kilobit•1 Mb = 1024 (210) Kb = 1048576 (220) b – 1 megabit •1 Gb = 1024 (210) Mb = 1073741824 (230) b – 1 gigabit•1 Tb = 1024 (210) Gb = 1099511627776 (240) b – 1 terabit
•1 byte = one 8 bit word (a sequence of 8 bits at the same address)
•1 B – 1 byte•1 KB = 1024 (210) bytes – 1 kilobyte•1 MB = 1024 (210) KB = 1048576 (220) B – 1 megabyte•1 GB = 1024 (210) MB = 1073741824 (230) B – 1 gigabyte•1 TB = 1024 (210) GB = 1099511627776 (240) B – 1 terabyte
