    First, your date is way off. Computer didn't come into widespread use until at least the late 1970s. My son graduated from a major university with a degree in engineering in 1978. He was the only one in his department in a major California company who had any experience with computers that year. My school system bought its first computers around 1980, and I bought mine (mainly for word processing) shortly after that. I didn't get on the internet until about 1996.

    I think your date should be 1980s (not 1950s) -- and your answer is correct.
