overflow

• Error Error from attempting to represent a number that is too precise. The value is rounded.

• Error Error from attempting to represent a number that is too large.

• Data with values that change continuously, or smoothly, over time. Some examples of analog data include music, colors of a painting, or position of a sprinter during a race.

• 8 bits

Round-off

• Error Error from attempting to represent a number that is too large.

• 
  Error Error from attempting to represent a number that is too precise. The value is rounded.

• A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is not reversible.

• A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.

Lossless Compression

• Data that changes discretely through a finite set of possible values

• A process for reducing the number of bits needed to represent something in which some information is lost or thrown away. This process is not reversible.

• 
  A process for creating a digital representation of analog data by measuring the analog data at regular intervals called samples.

• A process for reducing the number of bits needed to represent something without losing any information. This process is reversible.
