reCAPTCHA

Definition:

reCAPTCHA is a variation on CAPTCHA in that rather than displaying random letters and numbers, reCAPTCHA actually displays real words from old texts that have been digitally scanned. The words displayed were not understood by the computers that scanned them. Thus, not only are you preventing spam by entering the reCAPTCHA words, you are actually helping to decipher the words and bringing the old texts into the digital world.

Here's a word you may not know...

megabyte

A megabyte (MB) describes how much information can be stored on a device. Although the actual numbers are slightly higher, it is easiest to think of 1 megabyte as 1,000 kilobytes.

For reference, a digital picture typically takes about 3-6 megabytes (3 MB - 6 MB) of storage space.
