IPS is a better determiner of computer performance.
IPS is instructions per second which is a rating of how many instructions can be executed by a processor in a given second.
Replace common sequence of character with a single codeword,or symbol that points to a dictionary of the original characters, or to the original occurrence of the word.
Compression reduces file size that makes more place on HDD
Reduction of the space required for storage by an algorithm which converts the data to a smaller number of bits while preserving the information content.
b. Describe a benefit of compression.
c. Describe dictionary-based compression.
d. Describe run-length encoding.
A kind of compression algorithm which replaces sequences ("runs") of consecutive repeated characters (or other units of data) with a single character and the length of the run.
