UGC NET Questions (Paper – 1)

Compression encodes data more compactly, so files occupy less storage and need less bandwidth, speeding up transfers and saving resources.

Option A:
Resolution and quality are set when data is created; compression cannot magically increase original resolution and may even reduce quality in lossy schemes.

Option B:
This option correctly states the main practical benefit: smaller files mean more efficient storage and transmission.

Option C:
Lossless methods preserve all information, but lossy methods discard some details; so not all compression is information-perfect.

Option D:
Malware protection is the domain of security tools like antivirus and firewalls, not compression algorithms.
