Q64 / 100
What is the difference between "lossy" and "lossless" data compression, and which might be preferred for transmitting sensor telemetry from a constrained IoT device?
Correct! Well done.
Incorrect.
The correct answer is A) Lossy compression discards some data to achieve smaller size (acceptable for some sensor data where minor precision loss is fine); lossless compression preserves all original data exactly, useful when exact values matter
A
Correct Answer
Lossy compression discards some data to achieve smaller size (acceptable for some sensor data where minor precision loss is fine); lossless compression preserves all original data exactly, useful when exact values matter
Explanation
The choice depends on the application — e.g., minor precision loss in a temperature reading might be acceptable with lossy compression to save bandwidth, while financial or critical measurement data may require lossless methods.
