A platform can be seen both as a constraint on the application development process â the application is written for such-and-such a platform â and an assistance to the development process, in that they provide low-level functionality ready-made. An application, such as a spreadsheet or word processor, which hosts software written in an application-specific scripting language, such as an Excel macro. 2  This can be extended to writing fully-fledged applications with the Microsoft Office suite as a platform.
Pax Romana means roman peace, or literally, the peace of Rome. It lasted roughly 200 years and was a time of prosperity ad relative peace for the empire.
The Roman Republic was gone. In its place, the government was now a dictatorship, under the leadership of an emperor. The first Roman emperor was Augustus, the adopted son of Julius Caesar. He was emperor for 45 years. This was the beginning of the Pax Romana or Roman Peace. This is a very misleading title. There wasn't really peace. Rome continued to expand the empire, mostly through conquest. Rome itself was still beset by criminals and sometimes riots. It is called the Pax Romana because the empire itself was stable. The people knew that there was an emperor to run things and Roman legions to take care of wars and riots. They didn't have to worry about somebody coming in and conquering Rome and destroying their beautiful city.
