Bit level device

Bit level device has several meanings, which can be separated by considering their antonyms:

* A "bit level device" provides its output in binary format, whereas a pulse level device outputs raw voltages. A digital circuit or computer needs a separate controller or converter device to receive information from a pulse level device.

* A "bit level device" considers the data a continuous stream of information, whereas a packet level device divides the data into packets.

* A "bit level device" sends and receives data one bit at a time. A byte level device sends and receives data a byte at a time, a word level device sends and receives a word at a time, etc.

* Also, a "bit level device" may refer to a device that considers the data it deals with "opaque", i.e. it doesn't care about the semantics, or meaning, of the data.
