Intel Corporation is an American multinational corporation and technology company headquartered in Santa Clara, California, in Silicon Valley. Intel Corporation was founded on July 18, 1968, by semiconductor pioneers Robert Noyce and Gordon Moore (of Moore's law), and is associated with the executive leadership and vision of Andrew Grove. 

It is the world's largest and highest valued semiconductor chip manufacturer based on revenue, and is the inventor of the x86 series of microprocessors, the processors found in most personal computers (PCs). Intel ranked No. 46 in the 2018 Fortune 500 list of the largest United States corporations by total revenue. Intel is incorporated in Delaware.

x86 is a family of instruction set architectures initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address.

The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486 processors.
