A dissertation, more commonly known as a thesis, is a research paper that needs to be submitted for a professional qualification. A thesis is a pretty popular name among university students since it is required to obtain your academic degree. It is a very comprehensive research paper, which means that the writer has to use multiple sources to prepare it. However, although the sources can be used to introduce new data, support an assumption or cite relevant information, it doesn’t mean you can simply copy-paste someone else’s work, as this would result in something called plagiarism.

Different types of plagiarism may arise in your work. It can sometimes be unintentional, though there are other types of plagiarism as well, such as patchwork plagiarism, intentional plagiarism, or paraphrasing plagiarism.
