SLR12: Client-Server & Compression

What is the primary role of a client in a client-server interaction?

• To store web pages

• To request and display web pages

• To process database queries

• To manage network traffic

Which of the following is typically performed on the client side?

• Database queries

• Initial data validation

• Complex calculations

• Data encryption

What is a key advantage of performing tasks on the client side?

• Increased server load

• Reduced web traffic

• Enhanced data security

• Improved database management

Which type of processing is responsible for detailed validation and database updates?

• Client-side processing

• Server-side processing

• Network-side processing

• User-side processing

What is the main purpose of file compression?

• To increase file size

• To reduce file size and download time

• To enhance file quality

• To complicate data transmission

Which compression method allows for the original file to be perfectly reconstructed?

• Lossy compression

• Lossless compression

• Hybrid compression

• Partial compression

What is a common use case for lossy compression?

• Text documents

• Executable programs

• Multimedia files like images and audio

• Database files

Why is lossy compression not suitable for text documents?

• It increases file size

• It loses data that cannot be recovered

• It enhances file quality

• It is too slow

What is the effect of increasing colour depth in an image?

• Decreases file size

• Increases file size

• Reduces colour variety

• Enhances compression

Which of the following is a characteristic of lossless compression?

• Some data is lost

• Original data is fully recoverable

• It is only suitable for audio files

• It significantly reduces quality
