Back

16

Front

Which of the following is true of how computers represent numbers? Options: With a fixed number of bits some numbers are too large to represent in a computer which will lead to overflow errors., Using a fixed but large number of bits can eliminate the possibility of round off error when representing numbers in binary, Using a fixed but large number of bits, for example 128, eliminates the possibility of overflow errors., With a large but fixed number of bits it is possible to eliminate either round-off errors or overflow errors, but not both.

Back

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

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? The image can no longer be represented using bits. The image will have been converted into an analog form. The image will require more pixels to display it on the screen. The image will require fewer bits in order to be represented.

Back

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