A home computer was the description of the second generation of desktop computers, entering the market in 1977 and becoming common during the 1980s. They are also members of the class known as personal computers. These computers typically cost much less than business, scientific or engineering-oriented desktop personal computers, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business personal computers, and was usually sold for purposes of education, game play, and personal productivity use.
