How Do Computers Save Data? Part 2: Encoding Sound, Images and Video

[@davegraham7550]

Good suscripción of sound waves to digital. Can understand clearly from this. Fidelity depends on how my up down divisions and how how frequently these are made in time.

[@davegraham7550]

How many..

[@CodingCoach]

Yes, then later compression might additionally effect fidelity if lossy. But the goal of lossy algorithms is not to, see here: kzbin.info/www/bejne/nZ6roIuVetaKfJY for more

Excellent explanation, thank you very much. Can your share the presentation please? It's a great material. Thanks in advance

[@davegraham7550]

Like your "a" there. Do you know the website and learning materials at "computer science unplugged"?

[@CodingCoach]

I have not been to that site yet, but I will be checking it out later today, thank you for the link! I participate in local hour of code events. It is a lot of fun working with elementary students!
