sse definition1. Short for Simple Sharing Extension, SSE is a RSS extension from Microsoft that takes sharing information only unidirectional to bidirectional. For example, if you were using a calendar that was utilizing SSE and you updated appointments on your calendar anyone subscribed to that SSE would also have their calendar updated.

2. Short for Streaming SIMD Extensions, SSE, originally known as Internet Streaming SIMD Extensions (ISSE), are instructions for multimedia programs first used on the Pentium III.

SSE has been expanded on with SSE2, which was introduced with the Pentium 4, SSE3, and SSSE3.
