Digitizing sound a. achieves perfection using an unlimited number of bits. b. is accomplished via compression using MPEG. c. is accomplished using bits to represent both positive and negative values. d. requires lossless-compression techniques.

Option(c) is correct

Explanation:

Digitizing sound is defined as conversion of analog sound of digits into digital sound of digits. Digitized sound is depicted through bits that address positive and negative values .This is helping in accessing and sharing information.

Other options are incorrect because unlimited number of bits,compression through MPEG and lossless compression are not characteristics of digitizing sound.Thus, the correct option is option(c).

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
