The Age of Information (AoI) is a novel elegant metric introduced in the early 2010s to improve timeliness of the information received over a network and prediction quality. Value of Information (VoIU), more recently introduced similarly quantifies the benefit of obtaining sensory updates over a network. This brief tutorial treats the fundamentals of their theory and applications, while early developments in the field including designs and benefits are discussed. We indicate that AoI is not limited to networking and the initial results can be generalized into several directions, such as sampling theory, scheduling and even learning.
