A: Compressing a file has the potential of significantly reducing its size. Actual
reduction depends primarily on the number and proximity of redundant blocks of
information in the file. A reduction in file size means fewer bytes are transferred
when sending a file to a datalogger. Compression can reduce transfer times
significantly over slow or high-latency links, and can reduce line charges when
using pay-by-the-byte data plans. Compression is of particular benefit when
transmitting programs or OSs over low-baud rate terrestrial radio, satellite, or
restricted cellular-data plans.
