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.
Unfortunately, records do not tell us how long it took to build Roman roads or how large the road gangs were that built them. The Appian WayââQueen of Roadsâ and forerunner of many other Roman roads on three continentsâwas begun in 312 B.C. as a road for use in the Samnite Wars. The 211 km. (132 mi.) to Capua must have been completed within about a decade. Ultimately, the Appian Way reached southward 576 km. (360 mi.) from Rome to Brundisium on the Adriatic Sea. The road system was gradually extended through the efforts of numerous Roman emperors. Agustus, Tiberius, Claudius, and Vespasian were among those who launched great road-building projects.
