Comparing the computer and the brain has been instructive to both computer engineers and neuroscientists.
The brain is not slow nor imprecise in performing calculations.
For example, a professional tennis player can follow the trajectory of a tennis ball after it is served at speed as high as 160 miles per hour, move to the best spot, position his arm, and swing the racket to return the ball within a few hundred milliseconds. It can accomplish all these tasks with power consumption about tenfold less than a personal computer.
This is all possible because the brain employs serial and parallel processing, while computer tasks are mainly performed in serial steps.

By studying people with amnesia, it seems that short-term and long-term memories don't form in precisely the same way, nor do declarative and procedural memories.
Memories are held within groups of neurons called cell assemblies. They fire as a group in response to a specific stimulus, such as recognising your friend's face.
The more neurons fire together, the more the interconnection of the cells strengthen. We experience the nerves' collective activity as a memory.
