Peer review is a process in which other scholars in the author's field or specialty critically assess a draft of the article. Peer reviewed, or refereed, journals are scholarly journals that only publish articles that have gone through this review process.

A scholarly journal is visibly different from other periodicals/magazines, but sometimes it's hard to tell. You can look on the journal's web page (often under the "About" or "For Authors" link.) Or you can a tool called Ulrichsweb Global Serials Directory to check.
