Web Audio and Web Coding Final Practice Quiz

The practice quiz below covers much of the content in the Web audio section of MakePages.com as well as content from the XHTML and CSS sections. This quiz is intended for students studying privately with Dr. Estrella or in university courses. Each time you take the quiz, your results will be sent to Dr. Estrella by e-mail. Take the quiz as many times as needed to achieve a perfect score. This practice quiz will help Duquesne students with reading comprehension and better prepare them for the real quizzes to be given via Blackboard.

    2. CODEC stands for Compression Decompression. A codec is a set of rules that determines how data is removed from a file to reduce its file size. Today's codecs result in lossless compression.
    3. CODEC stands for Compression Decompression. A codec is a set of rules that determines how data is removed from a file to reduce its file size. Today's codecs result in lossy compression but the audible loss in quality is minimal.
    4. CODEC stands for Compression Decompression. A codec is a set of rules that determines how data is added to a file to increase the audio quality of the file.
  36. What is MIDI?
    1. MIDI is part of the QuickTime software.
