The topic of recent advances in information technology has attracted a wide range of articles on technology theory, applications from many aspects, and design methods of information technology. Reviewing the papers in this topic, it is clear that all fields such as computer science, cloud computing, wireless sensor network, prediction, image annotation, and storage have been involved. And the publications about recent advances in information technology tackled significant recent developments in the fields mentioned above, both of a foundational and applicable character.

Also, we can easily find that most contributors regard “information technology” as synonymous with tools such as the computer, mobile, and tablet and such issues as instructional design, mobile learning, social networking, and open sources.
