Format refers to the arrangement or organization of information in a specific way. It can apply to various contexts, such as documents, images, or data. For example, a text document may be formatted using headings, bullet points, and paragraphs to enhance readability. Different formats serve different purposes, like PDF for preserving layout or HTML for web content. In digital media, format also indicates the type of file, such as JPEG for images or MP3 for audio. Each format has its own characteristics, affecting quality, size, and compatibility with software or devices. Choosing the right format is essential for effective communication and usability.
