During data storage, the changing voltage in the read-write head makes a record of the data on the magnetic surface of the disk. During data retrieval, a changing voltage is induced in the read-write head by the spinning magnetic fields on the disk surface. The direction of the spike indicates a change from 0 to 1, or from 1 to 0. The g raphic below shows a measu red induced voltage with three spikes. Background on Neural Networks Neural networks borrow ideas from human information processing .
Information is represented by numbers and processed in parallel.
The emphasis is on what is learned and not on how it is represented internally. Now ask your friend. Both of you came up with the same answer, that's what counts. How your brain did it, is not important. The basic structure of a neural network is given in the picture below.
