- Course is the broadest term for the study of a subject. It could be used to refer to an entire degree program, but it is most appropriately applied to a specific subject such as First Year English Literature.
- Class is more specific and is most properly applied to a section of a course taught by one instructor to one group of students at a certain scheduled time.
- Lesson is the most specific and implies a particular unit of instruction, such as would be delivered by a particular instructor to a particular class on a given day.

The contents of the data lake stream in from a source to fill the lake, and various users of the lake can come to examine, dive in, or take samples."

The World's First $9 Computer: Meet Chip by Next Thing Co.
"...Oakland, CA is Next Thing Co. a team of nine artists and engineers who are pursuing the dream of a lower cost single board computer. Today they’ve unveiled their progress on Kickstarter, offering a $9 development board called Chip.
The board is Open Hardware, runs a flavor of Debian Linux, and boasts a 1Ghz R8 ARM processor, 512MB of RAM, and 4GB of eMMC storage. It is more powerful than a Raspberry Pi B+ and equal to the BeagleBone Black in clock speed, RAM, and storage. Differentiating Chip from Beagle is its built-in WiFi, Bluetooth, and the ease in which it can be made portable, thanks to circuitry that handles battery operation."
