Although technology may seem like a contemporary development, humans have been using technology since they began converting natural resources into tools. For example, the understanding of fire and its use in prehistoric cooking could be considered a facet of technology.

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.
