Answer by taking a quote from the following article:

Steve Wozniak was born in San Jose, California, the son of Francis Jacob "Jerry" Wozniak (1925-1994) from Michigan and Margaret Louise Wozniak (nee Kern) (1923-2014) from Washington State. He graduated from Homestead High School in 1968. The name on Wozniak's birth certificate is "Stephan Gary Wozniak", but Steve's mother said that she intended it to be spelled "Stephen", which is what he uses. Wozniak has mentioned his surname being Polish and Ukrainian and spoken of his Polish descent, but stated that he does not know the origin of some other people with the Wozniak surname because he is "no heritage expert".

In 1969, Wozniak returned to the Bay Area after being expelled from University of Colorado Boulder in his first year for sending prank messages on the university's computer system. During this time, as a self-taught project, Wozniak designed and built a "Cream Soda" computer with his friend Bill Fernandez. He later re-enrolled at De Anza College and transferred to University of California, Berkeley in 1971. Before focusing his attention on Apple, he was employed at Hewlett-Packard (HP) where he designed calculators. It was during this time that he befriended Steve Jobs. Wozniak was introduced to Jobs by Fernandez, who attended Homestead High School with Jobs in 1971. Jobs and Wozniak became friends when Jobs worked for the summer at HP, where Wozniak too was employed, working on a mainframe computer. This was recounted by Wozniak in a 2007 interview with ABC News, of how and when he first met Jobs: "We first met in 1971 during my college years, while he was in high school. A friend said, 'you should meet Steve Jobs, because he likes electronics and he also plays pranks.' So he introduced us." In 1973, Jobs was working for arcade game company Atari, Inc. in Los Gatos, California. He was assigned to create a circuit board for the arcade video game Breakout. According to Atari co-founder Nolan Bushnell, Atari offered $100 (equivalent to $551 in 2017) for each chip that was eliminated in the machine. Jobs had little knowledge of circuit board design and made a deal with Wozniak to split the fee evenly between them if Wozniak could minimize the number of chips. Wozniak reduced the number of chips by 50, by using RAM for the brick representation. Too complex to be fully comprehended at the time, the fact that this prototype also had no scoring or coin mechanisms meant Woz's prototype could not be used. Jobs was paid the full bonus regardless. Jobs told Wozniak that Atari gave them only $700 and that Wozniak's share was thus $350 (equivalent to $1,929 in 2017). Wozniak did not learn about the actual $5,000 bonus (equivalent to $27,564 in 2017) until ten years later, but said that if Jobs had told him about it and had said he needed the money, Wozniak would have given it to him. On June 29, 1975 Wozniak tested his first working prototype, displaying a few letters and running sample programs. It was the first time in history that a character displayed on a TV screen was generated by a home computer. With the Apple I design, he and Jobs were largely working to impress other members of the Palo Alto-based Homebrew Computer Club, a local group of electronics hobbyists interested in computing. The Club was one of several key centers which established the home hobbyist era, essentially creating the microcomputer industry over the next few decades. Unlike other Homebrew designs, the Apple had an easy-to-achieve video capability that drew a crowd when it was unveiled.
