How I get 0 & 1 stored in memory?

We are save any information in hardisk this is form of 0&1. This is making North pole and south pole in magnetic material. If north pole is maked down side so we say 0, if north pole is maked upper side so we say 1. This is for us 0&1, but this is for computer North & South Pole's direction.

• RAM(Random Access Memory) has in capacitors. Capacitor's in holding charge.

• Capacitors in has charge so we say 0, has not charge we say 1.
• 1 GB RAM    1 GB  = 1024 MB
•                                  = 1024 X 1024 KB
•                                  = 1024 X 1024 X 1024 bytes
•                                  =1024 X 1024 X 1024 X 8 bits.

• Processor  its have in UNITS,Units have in small small registers or this registers are makes from helps fliflop, Flip-flop is a circuit of store 1 binary digit.
