    Default error correction and detection and technology

    hey guys,
    please I wanna know why a certain error correction or detection is used with a certain technology or protocol, for example in TCP it uses either FEC or ARQ but why not CRC or check sum for example ?
    why UDP uses check sum not FEC ?

    Homework? Google is a good place to start. Your textbook is probably a pretty good resource too.
