Understanding File Compression 31

What is compression primarily used for in digital data?

• Expanding data usage

• Enhancing image quality

• Reducing file size

• Increasing file size

What does lossy compression do to the file size?

• Expands the data temporarily

• Increases it

• Reduces it by removing some data permanently

• Maintains the original size

Which type of compression allows the original form to be restored?

• Lossy compression

• Temporary compression

• Lossless compression

• Permanent compression

What is a common use of lossy compression?

• Software installation files

• Text files

• Video and audio files

• Storing legal documents

Which file format is typically associated with lossless compression?

• GIF

• JPEG

• MP3

• PNG

What is a drawback of lossy compression?

• Higher quality

• Larger file sizes

• Faster decompression

• Lower quality

What is an advantage of lossless compression?

• Ability to restore to original quality

• Reduced color quality

• Smaller file sizes than lossy

• Faster data transmission

How does lossy compression typically reduce file size?

• By duplicating data

• By encrypting data

• By eliminating some data

• By compressing data temporarily

What is a basic example of lossless compression?

• Reducing the number of colors in images

• Encoding repeated characters in text

• Increasing the bitrate of audio files

• Decreasing the resolution of videos

Why is file compression crucial?

• For slowing down data transfer

• For increasing internet costs

• For efficient data management

• For creating digital art
