1 bit = a single digit number in base-2 = 0 or 1

1 byte (B) = a set of 8 bits that represent a single character in the computer's memory = 8 bits (B)

1 kilobyte (KB)     = 2 to the 10th power = 1,024 bytes

1 megabyte (MB) = 2 to the 20th power = 1,024 kilobytes    = 1,048,576 bytes

1 gigabyte (GB)    = 2 to the 30th power = 1,024 megabytes = 1,073,741,824 bytes

1 terabyte (TB)     = 2 to the 40th power = 1,024 gigabytes  = 1,099,511,627,776 bytes

1 petabyte (PB)    = 2 to the 50th power = 1,024 terabytes   = 1,125,899,906,842,624 bytes

1 exabyte (EB)      = 2 to the 60th power = 1,024 petabytes  = 1,152,921,504,606,846,976 bytes

1 zettabyte (ZB)   = 2 to the 70th power = 1,024 exabytes    = 1,180,591,620,717,411,303,424 bytes

1 yottabyte (YB)  = 2 to the 80th power = 1,024 zettabytes = 1,208,925,819,614,629,174,706,176 bytes
