Synonomous with 'refereed', peer review is a formal process whereby any article submitted to a journal or conference is sent to several established scholars in that field of study, who may suggest improvements.
It is worth noting that some quite scholarly journals and conferences are not peer reviewed. Also, not everything in a publication with 'peer review' status will have been peer reviewed, eg editorial opinion pieces, book reviews etc.
To see if a journal is peer-reviewed you could check the Ulrich's website via the library databases page. Search by journal title.
