Data Compression Quiz

What is the main purpose of data compression?

• To increase file size

• To reduce file size

• To improve file quality

• To slow down download times

Which type of compression permanently loses some data?

• Lossy compression

• Lossless compression

• Run Length Encoding

• Huffman encoding

What is the main difference between lossy and lossless compression techniques?

• Lossless compression does not reduce file size

• Lossy compression reduces file size without losing data

• Lossless compression permanently loses some data

• Lossy compression reduces file size but loses some data permanently

Which compression technique reduces file size without losing any of the original data?

• Lossless compression

• Lossy compression

• Huffman encoding

• Run Length Encoding

What is the purpose of lossy compression?

• To permanently lose some data to reduce file size

• To reduce file size without losing any data

• To improve file quality without reducing file size

• To increase file size without losing any data
