Analog Data
Data with values that change continuously/smoothly over time
EX. of Analog Data
Music, color of a painting, or position of a sprinter during a race.
Digital Data
Data that changes discretely through a finite set of possible values
Sampling
A process for creating digital representation of analog data by measuring the analog data with samples
Lossless Compression
process of reducing the number of bits needed to represent something without losing any info (reversible )
Lossy Compression
Process of reducing number of bits needed to represent something in which some info is lost or thrown away (not reversible)
