Journal papers are quantitative, have an impact factor, are indexed in databases like Web of Science and Scopus, have volumes and issues, and do not have a fixed deadline. Conference papers are qualitative, have levels like A or B, are indexed, have proceedings, must be submitted by a deadline, and are published by companies like Springer. The impact factor of a journal is calculated by dividing the number of citations in a year by the total number of articles published in the previous two years. Indexing provides recognition of a journal's authenticity and original content.
