Term of the Day - Google mg

Yes, what does the word "Google" mean. Yes, I know its a search engine. But have you thought about what the actual definition of the word "Google" is? The brand "Google" is derived from the mathematical number "Googol". Googol is the name of the digit that has "1" followed by a "hundred zeros" after it. Like 1 million is 1 followed by 6 zeros. Similary 1 googol is 1 followed by a hundered zeros.


Google search engine choose this name, because they wanted such a large number to indicate how extensive their search results are.
