SPARC Architecture
The Solaris operating system runs on SPARC systems. SPARC—Scalable Processor Architecture—is a 32- and 64-bit microprocessor architecture from Sun Microsystems that is based on Reduced Instruction Set Computing (RISC) architecture. SPARC has become a widely used architecture for hardware used with Unix-based operating systems, including Sun's Solaris systems. SPARC is an open architecture that is available for licensing to microprocessor manufacturers through SPARC International.
