Silicon Valley is a nickname for the southern portion of the San Francisco Bay Area, in the northern part of the U.S. state of California.
San Francisco, officially the City and County of San Francisco, is the cultural, commercial, and financial center of Northern California and the only consolidated city-county in California.
California is the most populous state in the United States and the third most extensive by area.
A U.S. state is a constituent political entity of the United States.

The "valley" in its name refers to the Santa Clara Valley in Santa Clara County, which includes the city of San Jose and surrounding cities and towns, where the region has been traditionally centered.

The region has expanded to include the southern half of the San Francisco Peninsula in San Mateo County, and southern portions of the East Bay in Alameda County.
The San Francisco Peninsula is a peninsula in the San Francisco Bay Area that separates San Francisco Bay from the Pacific Ocean.
The word "silicon" originally referred to the large number of silicon chip innovators and manufacturers in the region, but the area is now the home to many of the world's largest high-tech corporations, including the headquarters of 39 businesses in the Fortune 1000, and thousands of startup companies.
High technology, often abbreviated to high tech is technology that is at the cutting edge: the most advanced technology available.
Fortune 1000 is a reference to a list maintained by the American business magazine Fortune.
Silicon Valley also accounts for one-third of all of the venture capital investment in the United States, which has helped it to become a leading hub and startup ecosystem for high-tech innovation and scientific development.
Venture capital is a type of private equity, a form of financing that is provided by firms or funds to small, early-stage, emerging firms that are deemed to have high growth potential, or which have demonstrated high growth.
A startup ecosystem is formed by people, startups in their various stages and various types of organizations in a location, interacting as a system to create and scale new startup companies.
The United States of America, commonly referred to as the United States or America, is a country in the Americas.
It was in the Valley that the silicon-based integrated circuit, the microprocessor, and the microcomputer, among other key technologies, were developed.
A microprocessor is a computer processor which incorporates the functions of a computer's central processing unit on a single integrated circuit, or at most a few integrated circuits.
An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material, normally silicon.
A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically.
As of 2013, the region employed about a quarter of a million information technology workers.
Information technology is the application of computers and internet to store, retrieve, transmit, and manipulate data, or information, often in the context of a business or other enterprise.
As more high-tech companies were established across the Santa Clara Valley, and then north towards the Bay Area's two other major cities, San Francisco and Oakland, the "Silicon Valley" name eventually came to refer to all high-tech businesses in the region.
The term is now generally used as a synecdoche for the American high-technology economic sector.
A synecdoche is a figure of speech in which a term for a part of something refers to the whole of something or vice versa.
One classical breakdown of economic activity distinguishes three sectors:
The name also became a global synonym for leading high-tech research and enterprises, and thus inspired similar named locations, as well as research parks and technology centers with a comparable structure all around the world.
