All we have is a byte stream from 'Jefri'.
In particular each process has three standard streams, that are examples of unidirectional byte streams.
A pipe mechanism is often used to connect them between processes, to enable process-to-process byte streams.
The Internet media type for an arbitrary byte stream is .
Other media types are defined for byte streams in well-known formats.
As an example, a Fletcher-8 checksum shall be calculated and verified for a byte stream of 0x01 0x02.
The transmitted byte stream is 0x01 0x02 0xF9 0x04.
If the byte stream is subject to corruption then some encodings recover better than others.
The standard encoding method uses a simple translation of the fields into a byte stream.
The two byte streams could be combined, used to find data in tables, or counted to determine the frequency of various values.
