In computing, a platform describes some sort of hardware architecture and software framework (including application frameworks), that allows software to run. Typical platforms include a computer's architecture, operating system, programming languages and related user interface (runtime libraries or graphical user interface).
Role in softwareEdit
A platform is a crucial element in software development. A platform might be simply defined as 'a place to launch software'. It is an agreement that the platform provider gave to the software developer that logic code will interpret consistently as long as the platform is running on top of other platforms. Logic code includes byte code, source code, and machine code.
Microsoft .NET is an umbrella term that applies to a wide collection of products and technologies from Microsoft. Most have in common a dependence on the Microsoft .NET Framework.
Java programs are a typical example of the latter point. Java source code is "compiled" to an intermediate-language bytecode which is then interpreted by an interpreter, the JVM, which then interfaces that program with the Java software libraries. In phones, PDAs and other wireless mobile devices, these libraries are the Java ME. Some phones, even without a full fledged OS, enable Java programs such as games to operate. Java and the bytecode are said to be platform independent. But this is because Java is the platform as well as a programming language. Software really cannot operate without a platform or be platform independent. The programming language is referred to here, meaning the programmer need not be concerned about the hardware or operating system platform, nor will the language change with a different platform.
