Networks can be an important part of everything from social organizations to computer systems. Students who pursue studies in network theory generally learn about the principles that underlie these systems as well as relevant real-world applications.

Requirements for the PhD program often involve the student having already obtained a Master’s degree. Additionally, a thesis or dissertation primarily consisting of original academic research must be submitted. In some countries, this work may even need to be defended in front of a panel.

Part time learning allows one to obtain part-time degrees even if one cannot attend school on a full-time basis. One can learn at his or own pace, gradually accumulating credits which count towards final qualification.
