Error Detection and Correction
英[ˈerə diˈtekʃən ænd kəˈrekʃən]美[ˈɛrɚ dɪˈtɛkʃən ənd kəˈrɛkʃən]
In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of digital data over unreliable communication channels. Many communication channels are subject to channel noise, and thus errors may be introduced during transmission from the source to a receiver.
