Background information in your Introduction should indicate the root of the problem being studied, its scope, and the extent to which previous studies have successfully investigated the problem, noting, in particular, where gaps exist that your study attempts to address.
In this manner, what is the difference between background of the study and RRL?
Background to a study involves a critical evaluation of the context for a study. This may range from situational analysis to the historical evaluation of the gap where a study fits. Literature review refers to a study of relevant ideas that you may use to compare and contrast the concepts under investigation.
