Question

permanently discards data

lossy compression
lossless compression

Explanation:

🆕 New Concept Discovered: Data Compression Types
Reducing file size by removing unnecessary data.

Step 1: Understand the definition

The question asks to match the description "Permanently discards data" to the correct type of data compression.

Step 2: Compare compression types

• Lossy Compression: This method reduces file size by permanently removing (discarding) non-essential information. Once compressed, the original, uncompressed data cannot be perfectly reconstructed.
• Lossless Compression: This method reduces file size by rewriting the data more efficiently without losing any information. The original data can be reconstructed perfectly.

Step 3: Match the description

Since the description specifies "Permanently discards data", it matches Lossy Compression.

Answer:

Lossy Compression
