It\u2019s good to have an understanding of the jargon of data.<\/p>\n\n\n\n

First of all, a bit (which is short for \u201cbinary digit\u201d) is the smallest form of data in a computer. Think of it as the atom. A bit can either be 0 or 1, which is binary. It is also generally used to measure the amount of data that is being transferred (say within a network or the Internet).<\/p>\n\n\n\n

A byte, on the other hand, is mostly for storage. Of course, the numbers of bytes can get large very fast. Let\u2019s see how in Table 2-1<\/a>.<\/p>\n\n\n\n

Types of data levels<\/p>\n\n\n\n

Unit<\/strong><\/th>Value<\/strong><\/th>Use Case<\/strong><\/th><\/tr><\/thead>
Megabyte<\/td>1,000 kilobytes<\/td>A small book<\/td><\/tr>
Gigabyte<\/td>1,000 megabytes<\/td>About 230 songs<\/td><\/tr>

Petabyte<\/td>1,000 terabytes<\/td>Five years of the Earth Observing System (EOS)<\/td><\/tr>

Zettabyte<\/td>1,000 exabytes<\/td>36,000 years of HD-TV video<\/td><\/tr>
Yottabytes<\/td>1,000 zettabytes<\/td>This would require a data center the size of Delaware and Rhode Island combined<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Data can also come from many different sources. Here is just a sampling:<\/p>\n\n\n\n

    \n
  • Web\/social (Facebook, Twitter, Instagram, YouTube)<\/li>\n\n\n\n
  • Biometric data (fitness trackers, genetics tests)<\/li>\n\n\n\n
  • Point of sale systems (from brick-and-mortar stores and e-commerce sites)<\/li>\n\n\n\n
  • Internet of Things or IoT (ID tags and smart devices)<\/li>\n\n\n\n
  • Cloud systems (business applications like Salesforce.com)<\/li>\n\n\n\n
  • Corporate databases and spreadsheets<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
