Conference papers refer to articles that are written with the goal of being accepted for presentation in a conference; typically an annual (or biannual) event with a specific scope where you can present your research results to the scholastic community, usually through an oral presentation, a poster presentation, or a tabled discussion (www.quora.com). It is different from a journal which is a regular periodical publication, printed perhaps monthly or bi-monthly, which contains collection of reviewed papers (https://academia.stackexchange.com).
