 Measure for digital information
1 byte = 8bits
1 kilobyte (KB) = 1,024 bytes
1 megabyte (MB) = 1024 kilobytes
1 gigabyte (GB) = 1,024MB
1 terabyte (TB) is 1,024GB
1 petabyte (PB) is 1,024TB
1 exabyte (EB) is 1,024PB
1 zettabyte (ZB) is 1,024EB
1 yottabyte (YB) 1,024ZB
We count in base 10 by powers of 10:
101 = 10
102 = 10*10 = 100
103 = 10*10*10 = 1,000
106 = 1,000,000
Computers count by base 2:
21 = 2
22 = 2*2 = 4
23 = 2*2*2 = 8
210 = 1,024
220 = 1,048,576
So in computer jargon, the following units are used:
