Many basic prerequisite college/school courses are entitiled "(course name) 101". Other courses that one would take at the same time may be titled "102", "103", etc. After taking "100" level courses, one progresses to "200" level courses. This numbering system allows for up to 99 courses in each diffculty level. When someone uses a phrase, i.e. "blogging 101", they are referring to basic principles for that subject that would be taught in a preliminary course.
