In addition to their fundamental use for interprocess communication, channels can be used as a primitive to implement various other concurrent programming constructs which can be realized as streams. For example, channels can be used to construct futures and promises , where a future is a one-element channel, and a promise is a process that ...
A simplistic example of ECC is to transmit each data bit three times, which is known as a (3,1) repetition code. Through a noisy channel, a receiver might see eight versions of the output, see table below.
Similarly, socket channels (java.nio.channels.SocketChannel and java.nio.channels.ServerSocketChannel) allow for data transfer between sockets and NIO buffers. FileChannel can be used to do a file copy, which is potentially far more efficient than using old read/write with a byte array. The typical code for this is:
A repetition code is a coding scheme that repeats the bits across a channel to achieve error-free communication. Given a stream of data to be transmitted, the data are divided into blocks of bits. Given a stream of data to be transmitted, the data are divided into blocks of bits.
In coding theory, decoding is the process of translating received messages into codewords of a given code. There have been many common methods of mapping messages to codewords. These are often used to recover messages sent over a noisy channel, such as a binary symmetric channel.
For example, the file rename command (variously called mv, move, or ren) is silent on success. Unless redirected , standard output is inherited from the parent process. In the case of an interactive shell, that is usually the text terminal which initiated the program.

In coding theory, the repetition code is one of the most basic linear error-correcting codes. In order to transmit a message over a noisy channel that may corrupt the transmission in a few places, the idea of the repetition code is to just repeat the message several times. The hope is that the channel corrupts only a minority of these repetitions.
