“Bad computer memory is one of the three main reasons for random system failures; the other two are heat (usually caused by fans or heatsinks being blocked with dust) and bad power.” — Serdar Yegulalp

Today’s WhatIs.com Word of the Day is memory map, a massive table that tells your computer how much memory is available and helps ensure that data is always written to, and read from, the proper places.

There’s an interesting article at Forbes.com this week about recent advances in understanding human memory. Author Roger Kay writes about his own memory issues and explains how memories may not be held in their entirety in the brain but are maintained as a kind of chemical residue of the original perception.

That means my brain, in effect, uses hash values to store and retrieve data.  Does that also mean that when I remember things incorrectly it’s because my brain has suffered from a hash collision?  Makes sense to me!
