What file format does PNG stand for?

The correct answer is that PNG stands for Portable Network Graphics. This format was developed as a replacement for the older GIF (Graphics Interchange Format) and was designed to provide a more modern image format that supports lossless data compression. Unlike JPEG, which is a lossy format, PNG retains all image data, making it ideal for images that require high quality, such as graphics with text, line art, or images where you want to keep the original quality after editing.

The term "Portable" signifies that PNG files can be used across different platforms and networks without concern for compatibility, which was a significant advancement for graphic data exchange at the time of its creation. "Network" emphasizes that this format was developed with the internet in mind, ensuring that images could be easily transferred over various network protocols.

Understanding the difference between PNG and other image formats is crucial for selecting the right format for specific use cases, such as web design, digital art, or any situation where maintaining image quality is essential.
