is a very simple form of lossless data compression in which runs of data (that is, sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is most useful on data that contains many such runs.

Run-length encoding (RLE)

None of the above

The correct answer to the following question will be "Run-length encoding (RLE)".

Explanation:

RLE seems to be useful for replicated information, swapping it with a qualify as well as a copy of something like a repeat element.

Optimized dictionary strategies construct a table of sequences, then substitute appearances of chords with simpler codes.This is a straightforward type of data compression, where data runs become stored as an individual data count as well as a value rather than as the initial run.

Solution: the categorization of functional and non-functional requirement are as follows: some of the more typical functional requirements include: • business rules• transaction corrections, adjustments and cancellations• administrative functions• authentication• authorization levels• audit tracking• external interfaces• certification requirements• reporting requirements• historical data• legal or regulatory requirementswhile,some typical non-functional requirements are: • performance – for example response time, throughput, utilization, static volumetric• scalability• capacity• availability• reliability• recoverability• maintainability• serviceability• security• regulatory• manageability• environmental• data integrity• usability• interoperability
