Overview: Computers in Our World

Computers are everywhere. In fact, you can find them in some preny unlikely places, including your family car, your home appliances, and even your alarm clock! In the past two decades, computers have reshaped our lives at home, work, and school. The vast majority of businesses now use computerized equipment in some way, and most companies’ arc networked both internally and externally. More than half of all homes in the United States have at least one computer, and most of them are connected to the Internet. Workers who once had little use for technology now interact with computers almost every minute of the workday. This lesson examines the many types of computers that arc in common use today. Although this class will focus on personal computers, you will first learn about the wide variety of computers that people use, and the reasons they use them. As your knowledge of computers grows, you will understand that all computers—regardless of their size or purpose—arc basically similar. That is, they all operate on the same fundamental principles, are made from the same basic components, and need instructions to make them run.
