Personal computers were affordable and made it possible for anyone to use a computer without being familiar with programming. Spreadsheet and desktop publishing programs popularized the use of computers in homes, schools, and offices. The IBM PC was the first personal computer used widely in businesses. The Apple Macintosh first made its way into schools in the late 1980s. Today computers are everywhere.
Some people use computers to gather and organize information.
Others use them to create art or solve mathematical problems. You'll also find computer chips in VCRs, stereos, cars, microwaves, and other appliances.
