Abstract

The discussion over the advantages and disadvantages of the cloud computing is being held over the years. There are three models that are used in order to define has this technology will be used, such as SaaS, PaaS and IaaS. This paper provides the overview of the differences of those models and cover the concerns that are associated with the use of the cloud computing. Even though the future of any technology is not easy to predict, we try to analyze the current market of cloud computing and based on that try to predict how it will evolve with ...

Most researchers and scientist believe that there is no substitute for patient-doctor face to face interaction; however, telemedicine could be used to manage a few medical cases efficiently and remotely.

Cryptography is an art that is involved in writing and interpreting secret messages. It involves encrypting messages into symbols, numbers, and letters that form a different meaning to conceal the message. In other words, it is the use of codes to conceal a message. In the past, cryptography was very common, especially during epochs of combat where it was deployed to communicate coded messages (Bauer 34). It was an important tool that a particular community would use to conceal messages from their enemies. Today, this mode of communication is rarely used. However, codes are commonly used in technology, especially ...
