Digital images are pictures created or stored in a format that computers can process. They are made up of tiny dots called pixels, which combine to form the complete image. Each pixel has a specific color and brightness, allowing for detailed and vibrant pictures. Common formats for digital images include JPEG, PNG, and GIF. Digital images can be captured using devices like cameras and smartphones, or created using graphic design software. They can be easily shared, edited, and stored on various platforms, making them versatile for personal and professional use. Digital images play a crucial role in fields such as photography, advertising, and social media.
