ROM and RAM
RAM Random Access Memory or RAM is a form of data storage that can be accessed randomly at any time, in any order and from any physical location., allowing quick access and manipulation. RAM allows the computer to read data quickly to run applications. It allows reading and writing. It is non-volatile i.e. its contents are retained even when the device is powered off. Static RAM vs. Dynamic RAM Static RAM has a pair of transistors forcing each other on and off, so there are electric fields turning on channels to conduct and turn off the opposite transistor. This is a self-reinforcing state, so it can go on forever. In a dynamic RAM there is just a little bit of charge or not on the gate of a transistor. This charge will leak away in milliseconds, as there is nothing actively maintaining it all the time. So dynamic RAM need to have a refresh jolt every few milliseconds , where a pulse causes the read transistor to reinforce the charge level on its gate. Dyna...
