Which of the following is a lossless image compression technique?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: B
Explanation:

PNG (Portable Network Graphics) is a lossless image compression technique that preserves all the original data in the image.

Which of the following is a lossy image compression technique?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: A
Explanation:

JPEG (Joint Photographic Experts Group) is a lossy image compression technique that reduces the size of the image by discarding some of the data.

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

  1. Lossless compression preserves all the original data, while lossy compression discards some of the data.

  2. Lossless compression is faster than lossy compression.

  3. Lossless compression produces smaller files than lossy compression.

  4. Lossless compression is more complex than lossy compression.


Correct Option: A
Explanation:

The main difference between lossless and lossy image compression is that lossless compression preserves all the original data in the image, while lossy compression discards some of the data.

Which of the following image formats uses lossless compression?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: B
Explanation:

PNG (Portable Network Graphics) is a lossless image format that uses lossless compression to preserve all the original data in the image.

Which of the following image formats uses lossy compression?

  1. JPEG

  2. It produces smaller files than lossy compression.

  3. It is faster than lossy compression.

  4. It is more complex than lossy compression.


Correct Option: A
Explanation:

The main advantage of lossless image compression is that it preserves all the original data in the image.

What is the main disadvantage of lossless image compression?

  1. It produces larger files than lossy compression.

  2. It is slower than lossy compression.

  3. It is more complex than lossy compression.

  4. It is not as widely supported as lossy compression.


Correct Option: A
Explanation:

The main disadvantage of lossless image compression is that it produces larger files than lossy compression.

Which of the following image formats is best suited for storing high-quality images?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: B
Explanation:

PNG (Portable Network Graphics) is best suited for storing high-quality images because it uses lossless compression to preserve all the original data in the image.

Which of the following image formats is best suited for storing images on the web?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: A
Explanation:

JPEG (Joint Photographic Experts Group) is best suited for storing images on the web because it uses lossy compression to reduce the size of the image without significantly affecting the visual quality.

Which of the following image formats is best suited for storing animated images?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: C
Explanation:

GIF (Graphics Interchange Format) is best suited for storing animated images because it supports multiple frames and transparency.

Which of the following image formats is best suited for storing high-resolution images?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: D
Explanation:

BMP (Bitmap) is best suited for storing high-resolution images because it does not use any compression and preserves all the original data in the image.

Which of the following image formats is best suited for storing images with transparency?

  1. JPEG

  2. PNG

  3. GIF

  4. BMP


Correct Option: B
Explanation:

PNG (Portable Network Graphics) is best suited for storing images with transparency because it supports alpha channels.
