Re: Flipping a bit
Computer memory has transistor flip/flop switch circuits that are defined to be in one state or the other unless reset by the CPU. In practice individual bits are not set, but rather a group of bits such as a byte or a mulitple of bytes depending upon the the CPU and memory architecture which defines the smallest and largest addressable unit of memory. Of course regarding storage hard drives, the information is stored magnetically, but is also occasionally susceptible to errors.
