What lossless algorithm uses patterns and repetition to reduce file size?
Run-Length Encoding (RLE)
What is the process that makes the data uniform without changing the meaning?
What type of loop processes every item in a list?
For loop
Why does data need to be stored in binary?
Computers can only understand on and off switch circuits which are represented by 1s and 0s.
Why is lossy compression used over lossless compression sometimes?
Better reduction in file size for the quality.
What method involved two or more processors working on the same task?
Parallel processing

Clustering
What is the practice of summarizing or simplifying data to make it easier to manage and analyze?
Data abstraction
