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.
When the high infant mortality rate is factored in (life expectancy at birth) inhabitants of the Roman Empire had a life expectancy at birth of about 25 years. However, when infant mortality is factored out, life expectancy is doubled to the late-50s. If a Roman survived infancy to their mid-teens, they could, on average, expect near six decades of life, although of course many lived much longer or shorter lives for varied reasons.
