FIRSTLY,
every memory location in a computer is created equal. You can move stuff from one location to another without losing any information. In the brain, on the other hand, certain cells specialize in certain jobs. While there is considerable plasticity (the ability to change what some part of the brain does, enabling the brain to recover from injury), there's nothing like the uniformity seen in a computer.

Secondly, processing and memory are completely separated in a computer; not so in the brain.

Finally, data in computers is digital, and not really susceptible to "noise". In the brain, there are continuous voltages.

With those caveats, let's look at numbers. The brain contains 10^11
neurons -- in other words, 100 giganeurons. Each one has synapses
connecting it to up to 1000 other neurons. Many researchers believe that
memories are stored as patterns of synapse strengths. If we suppose that the strength of each synapse can take on any of 256 values, then each synapse ...more
