Jorge is sending a large image file to a friend as part of a shared classroom project. Which of the following is most likely true if Jorge opts to compress the image before sending it?

D. The image will require fewer bits in order to be represented.

how do computers represent complex information

Patterns of bits , Depending on context the same sequence of bits may represent different types of information, Abstractions that are represented by computing devices include numbers, characters, and color.

how do computers represent numbers?

With a fixed number of bits some numbers are too large to represent in a computer which will lead to overflow errors.

Analog

an NONdigital representation of something, such as a drawing on paper.

How does a computer represent data

as bits of 0 or 1

Lossless Compression

data compression techniques in which no data is lost.

Lossy Compression

data compression techniques in which some amount of data is lost. This technique attempts to eliminate redundant information.
