网上中文的讨论不多,以下摘一些英文的资料:
In computers, a platform is an underlying computer system on which application programs can run. On personal computers, Windows 2000 and the Mac OS X are examples of two different platforms. On enterprise servers or mainframes, IBM's S/390 is an example of a platform.
A platform is any base of technologies on which other technologies or processes are built.
The platform defines a standard around which a system can be developed.
