R093: L24 - Static Image Files

What does DPI/PPI stand for and what do they measure?

• DPI stands for Dots Per Inch, and PPI stands for Pixels Per Inch. They measure the resolution of images, with DPI referring to the print resolution and PPI referring to the display resolution.

• DPI stands for Digital Processing Interface, and PPI stands for Pixels Per Inch. They measure the speed of processors.

• DPI stands for Dots Per Inch, and PPI stands for Pixels Per Inch. They measure the color depth of images.

• DPI stands for Data Processing Index, and PPI stands for Pixels Per Inch. They measure the size of digital files.

An increase in resolution affects image quality by:

• Improving the clarity and detail of the image

• Decreasing the clarity and detail of the image

• Having no effect on the image quality

• Distorting the image

List the file formats associated with bitmap and vector graphics.

• JPEG, PNG, SVG, AI

• BMP, TIFF, EPS, PDF

• GIF, PSD, SVG, DXF

• BMP, JPEG, SVG, AI

What is compression?

• A process of reducing the size of data

• A method to increase data size

• A technique to duplicate data

• A way to delete data

Compression is needed because:

• it reduces the size of data for storage and transmission.

• it increases the size of data for better quality.

• it has no effect on data size.

• it is only used for encryption purposes.

Which of the following is a reason for using compression?

• Increase file size

• Save on storage space

• Decrease transfer speeds

• Use more bandwidth

List the types of files that can be compressed.

• Text files, Image files, Audio files, Video files

• Only Text files

• Only Image files

• Only Audio files

The difference between lossy and lossless compression is:

• Lossy compression reduces file size by removing some data, while lossless compression reduces file size without losing any data.

• Lossy compression increases file size by adding data, while lossless compression reduces file size by removing data.

• Lossy compression reduces file size without losing any data, while lossless compression increases file size by adding data.

• Lossy compression and lossless compression both reduce file size by removing data.

What is the primary benefit of using vector graphics over bitmap graphics?

• Vector graphics are easier to compress than bitmap graphics.

• Vector graphics are always smaller in file size than bitmap graphics.

• Vector graphics have a higher color depth than bitmap graphics.

• Vector graphics are resolution-independent and can be scaled without losing quality.

Which of the following is a common use for bitmap images?

• Storing text documents

• Creating logos and icons

• Designing scalable graphics

• Photographic images and detailed artwork
