RO93 - File Compression

What is compression?

• The process of increasing the size of something

• The process of reducing the size of something

• The process of changing the color of something

• The process of duplicating something

Why is data compression useful for email attachments?

• It makes emails take longer to send

• It allows sending larger files by reducing their size

• It increases the size of attachments

• It makes emails more colorful

What is lossy compression?

• A type of compression that makes files larger

• A type of compression that loses no data

• A type of compression that permanently eliminates some data

• A type of compression that can only be used on text files

Which file format is an example of lossy compression?

• ZIP

• TXT

• PNG

• JPEG

What is a drawback of lossy compression?

• It can only compress images

• It increases file size

• It reduces file quality

• It cannot be used on the internet

What is lossless compression?

• Compression that loses important data

• Compression that cannot be reversed

• Compression that reduces data size without losing information

• Compression that only works on audio files

What is a benefit of lossless compression?

• It is the only method used for video compression

• It allows files to be restored to their original quality

• It permanently removes some data for efficiency

• It significantly reduces file sizes compared to lossy compression

Which of the following is a characteristic of lossless compression?

• It results in a significant loss of quality

• It can only be applied to text files

• It allows the original data to be perfectly reconstructed from the compressed data

• It is not suitable for digital media files

How does compression affect the transmission of data over the internet?

• It increases the time required to transmit data

• It has no effect on the transmission speed

• It decreases the bandwidth required, potentially speeding up the transmission

• It only affects the transmission of video files

What is the primary advantage of using lossy compression for multimedia files?

• It enhances the quality of multimedia files

• It significantly reduces file sizes with minimal loss of quality

• It ensures that files can be decompressed into their original form

• It is the only method available for compressing multimedia files
