    With all due respect – On page 48 of the P5 notes following was the definition of a Petabyte:

    “The volume of big data held by large companies such as Walmart (supermarkets), Apple and EBay is measured in multiple petabytes. What’s a petabyte? It’s 1015 bytes (characters) of information. A typical disc on a personal computer (PC) holds 109 bytes (a gigabyte), so the big data depositories of these companies hold at least the data that could typically be held on 1 million PCs, perhaps even 10 to 20 million PCs.”

    Is it right cz it should be way bigger than That.

    It the petabyte should not be 1015: it should be 10 to the power 15.

    Similarly, the gigabyte should not be be 109: it should read 10 to the power 9.

    Sorry and thanks for pointing it out.

    We’ll change it.
