1.2n Compression

What is the main purpose of compression?

• To store fewer photos

• To increase the file size

• To reduce the file size

• To slow down data transfer

Which type of compression is suitable for images, sound, and video?

• Lossy compression

• Lossless compression

• Both types of compression

• No compression needed

What is the main drawback of lossy compression?

• It is reversible

• It reduces file size

• It affects quality

• It is suitable for all types of data

Which type of compression is most suitable for documents and executable files?

• Lossless compression

• No compression needed

• Lossy compression

• Both types of compression

What is the purpose of lossless compression?

• To reduce file size with some data loss

• To reduce file size without any data loss

• To increase file size with better quality

• To store more photos with higher quality

Which type of data is lossy compression applicable to?

• None of the above

• Text and executable files

• Images, sound, and video

• All types of data

What is the effect of lossy compression on the quality of the image or sound?

• It reduces the quality

• It sometimes reduces the quality

• It has no effect on the quality

• It improves the quality

What is the main advantage of lossless compression?

• It is irreversible

• It is less effective than lossy compression

• It can be used for all types of data

• It reduces file size significantly
