  • Home Computer

    Home Computer
    Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. I first had access to a computer in my 2nd grade class at school. Obviously, the need and access for computers has grown and evolved rapidly since then.
