So the data is encoded as a series of on and off, or ones and zeros. This is the digital system, it's an encoded language. The actually transfer and storage of the data exists in the analogue world. A flip flop is an electrical circuit, used to store a value, this is what the digital data is stored in with RAM.
The quality of the storage system/device and the retrieval of the data is all done in the analogue world. For example it could be via a cable, where the electrical signal energizes and de-energizes delivering the pattern representing the values of the data being conveyed. The device creating the analogue signal, electrically, through an oscillating stream of light, or a radio signal, what have you, the connecting medium through which the signal travels and the end device that through engineering has to read or discern what the signal represents have varying degrees of efficiency.
The encoding is called digital, as for the entire rest of the computing system including the transfer of the language it's electronics and can be transferred by light pulses or an electrical system, radio signals. All of these methods of transfer of a language are prone to mechanical limitations and failure.
Digital being the organized structure of the data may be perfect, the storage, retrieval and conversion from and back to the analogue world is not perfect. That is why the technology for storage, retrieval, computation and conversion is always being improved upon by engineering methods.
