Why Digital Storage of Data? Why Not Analog ?
The basic goal of digital memory is to provide a means to store and access binary data: sequences of 1's and 0's. The digital storage of information holds advantages over analog techniques much the same as digital communication of information holds advantages over analog communication. This is not to say that digital data storage is unequivocally superior to analog, but it does address some of the more common problems associated with analog techniques and thus finds immense popularity in both consumer and industrial applications.

War Between AC(TESLA) & DC(EDISON)
You might wonder why ac is even used. Isn’t it a lot more complicated than dc?
Well, ac is easy to generate from turbines, as you’ve just seen. Rotating coil-and magnet devices always produce ac, and in order to get dc from this, rectification and filtering are necessary. These processes can be difficult to achieve with high voltages.
