An overview provides a broad summary or general understanding of a subject. It highlights the main points, key concepts, and essential details without going into deep analysis. This helps readers quickly grasp the topic's significance and context, making it easier to engage with more detailed information later. In various fields, such as business, education, or science, an overview can serve as an introduction to reports, presentations, or articles. It sets the stage for what to expect, guiding the audience through the material. By offering a concise snapshot, overviews enhance comprehension and retention of information.
