What are the content of an abstract of a research?

An abstract of a research paper typically includes a brief overview of the study's objectives, methodology, results, and conclusions. It summarizes the key points and findings to provide readers with a quick understanding of the research's significance and relevance. The abstract should be concise and informative, allowing readers to determine whether the full paper is of interest to them. Generally, it is written last, despite appearing at the beginning of the paper.
