Q11. Which of the following is a lossless image file format?
a) .jpg
b) .gif
c) .png
d) .bmp
Show Answer
Correct Answer: c) .png
Explanation: PNG (Portable Network Graphics) is a lossless image file format that supports transparency and provides better compression than other lossless formats like BMP. Unlike JPEG, which uses lossy compression, PNG maintains the original image quality without any loss of data.
Q12. Which of the following is a vector graphics file format?
a) .jpg
b) .bmp
c) .svg
d) .png
Show Answer
Correct Answer: c) .svg
Explanation: SVG (Scalable Vector Graphics) is a vector graphics file format that uses XML to describe two-dimensional graphics. Unlike raster graphics formats like JPEG and PNG, vector graphics are resolution-independent and can be scaled without losing quality.
Q13. Which of the following is a common video file format?
a) .mp4
b) .jpg
c) .wav
