Technology is a major component of the city's economy, with more than 1,200 technology companies existing within the metro. This high density of technology companies has led to the nickname Silicon Forest being used to describe the Portland area, a reference to the abundance of trees in the region and to the Silicon Valley region in Northern California. The area also hosts facilities for software companies and online startup companies, some supported by local seed funding organizations and business incubators. Computer components manufacturer Intel is the Portland area's largest employer, providing jobs for more than 15,000 people, with several campuses to the west of central Portland in the city of Hillsboro.
