The Institute of Electrical and Electronics Engineers (IEEE) style is a numbered referencing style that uses citation numbers in the text of the paper, provided in square brackets, e.g. [1]. A full corresponding reference is listed at the end of the paper, next to the respective citation number.
The IEEE referencing system is commonly used in technical fields, typically electrical, electronic and computer systems engineering.
Before you write your Reference List or Bibliography, check with your professor which style they prefer you to use and refer to the instructions included with your assignment.
