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 when viewed together, they create the overall picture. Digital images can be captured using devices like cameras or created using software. These images can be saved in various file formats, such as JPEG, PNG, or GIF, each with its own characteristics. Digital images are widely used in many areas, including social media, websites, and graphic design, making them an essential part of modern communication and art.
