Sun Microsystems

A proponent of open systems and Unix, Sun Microsystems is also a major contributor to open source.

The company was founded in 1982 and is headquartered in Santa Clara, California and has a workforce of 34,440 people globally.

It provides a range of products related to computing, from computer servers and workstations based on its own SPARC chips, to storage systems and software, such as the Solaris operating system and Java platform.

For its first-quarter revenue, the American technology giant posted a 7 percent year-on-year dip to US$2.99 billion, while net loss was US$1.68 billion from net profit of US$89 million in the previous year.

Sun recently announced that it will chop up to 6,000 jobs, or 18 percent of the workforce, in a bid to create cost savings of US$700 million to US$800 million each year.
