It seems like there might be some repetition in your message. Here's a concise summary of what a summary is:
A summary condenses information from a source into a shorter form, rewording and restructuring the original content while retaining its main ideas and essential points. It differs from direct quotes or paraphrases, as it aims to provide a brief overview rather than an exact reproduction or close restatement of the original material.
