In those cases, when the destination of a bytestream (the consumer) uses bytes faster than they can be generated, the system uses process synchronization to make the destination wait until the next byte is available.

Often the contents of a bytestream are dynamically created, such as the data from the keyboard and other peripherals (/dev/tty), data from the pseudorandom number generator ( /dev/urandom), etc. Other media types are defined for bytestreams in well-known formats. The Internet media type for an arbitrary bytestream is application/octet-stream. One well-known example of a communication protocol which provides a byte-stream service to its clients is the Transmission Control Protocol (TCP) of the Internet protocol suite, which provides a bidirectional bytestream. Although typically implemented in low-level languages, some high-level languages such as Python and Java offer native interfaces for bitstream I/O. The Unix pipe mechanism provides bytestream communications between different processes.Ĭompression algorithms often code in bitstreams, as the 8 bits offered by a byte (the smallest addressable unit of memory) may be wasteful. In particular in Unix-like operating systems, each process has three standard streams, that are examples of unidirectional bytestreams. On most operating systems, including Unix-like and Windows, standard I/O libraries convert lower-level paged or buffered file access to a bytestream paradigm. In mathematics, several specific infinite sequences of bits have been studied for their mathematical properties these include the Baum–Sweet sequence, Ehrenfeucht–Mycielski sequence, Fibonacci word, Kolakoski sequence, regular paperfolding sequence, Rudin–Shapiro sequence, and Thue–Morse sequence. The detailed format of the bitstream for a particular FPGA is typically proprietary to the FPGA vendor.

Although most FPGAs also support a byte-parallel loading method as well, this usage may have originated based on the common method of configuring the FPGA from a serial bit stream, typically from a serial PROM or flash memory chip. The term bitstream is frequently used to describe the configuration data to be loaded into a field-programmable gate array (FPGA). In practice, bitstreams are not used directly to encode bytestreams a communication channel may use a signalling method that does not directly translate to bits (for instance, by transmitting signals of multiple frequencies) and typically also encodes other information such as framing and error correction together with its data.
