The tech industry has been circling around the terms brontobyte (a thousand yottabytes) and geopbyte (a thousand brontobytes) as the next levels in the big data hierarchy, but those are de facto terms. Merriam-Webster.com has no listing for either of those words.
GigaOM in their post “As data gets bigger, what comes after a yottabyte?” explained:
After a zettabyte comes yottabytes, which big data scientists use to talk about how much government data the NSA or FBI have on people altogther. Put it in terms of DVDs, a yottabyte would require 250 trillion of them. But we’ll eventually have to think bigger, and thanks to a presentation from Shantanu Gupta, director of Connected Intelligent Solutions at Intel (s intc), we now know the next-generation prefixes for going beyond the yottabyte: a brontobyte and a gegobyte.
A brontobyte, which isn’t an official SI prefix but is apparently recognized by some people in the measurement community, is a 1 followed by 27 zeros. Gupta uses it to describe the type of sensor data we’ll get from the internet of things. A gegobyte is 10 to the power of 30. It’s meaningless to think about how many DVDs that would be, but suffice it to say it’s more than I could watch in a lifetime.
A bit is a binary digit, the smallest increment of data on a computer. A bit can hold only one of two values: 0 or 1, corresponding to the electrical values of off or on, respectively.
Because bits are so small, you rarely work with information one bit at a time. Bits are usually assembled into a group of eight to form a byte. A byte contains enough information to store a single ASCII character, like "h".
