101 (pronounced "one-oh-one") is a topic for beginners in any area. It has all the basic principles and concepts that are expected in a particular field.
In American university course numbering systems, the number 101 is often used for an introductory course at a beginner's level in a department's subject area. This common numbering system was designed to make transfer between colleges easier. In theory, any numbered course in one academic institution should bring a student to the same standard as a similarly numbered course at other institutions.
According to this three number arrangement, the first digit corresponds to the college year (1 for freshman, 2 for sophomore, 3 for junior, 4 for senior in undergraduate courses, and 5 and above for graduate courses). The second digit corresponded to a particular subject or to a department (like English, Science, etc.), and the third digit referred to a sequence number within a series of courses on the same subject. Sometimes there are prerequisites, so for instance an English 201 course might not be taken before passing English 101 and 102.
