Chapter 10
Module 10 Summary
Chapter 10 has a general overview of the data that gets sent through the internet. It talks about how data is values that represent concepts, like numbers, text, readings, and values. That data can either come from political polls, school grades, lab reports, financial statements, and much more. I know quite a bit of data due to excel classes I’ve taken, but it’s always fun to learn more about it.
When data is initially collected, it’s unstructured data, meaning not much sense can be made out of it especially on it’s own. But organizing the data on a spreadsheet can help finding information a lot easier. In a spread sheet data is organized in rows and columns where each row or column can hold many identifiers for a single piece of data, such a card number, account number, phone, by a customer’s name. A more advanced organization method would be a database which I’ve only used a few times, they’re amazing for organization since it lets you view and connect different tables in a more efficient manner than what excel, or any other spreadsheet program, let’s you do.
Something fun that the chapter covers is something I learned in my programming class, which was data structures and how they work. Seeing them in a text book is fun though I would rather work with them using code than any other way, it seems more familiar and easier to apply logic to by using instructions.
