devices, or devices. Software refers to the instructions, or programs, that tell the hardware what to do. A word processing program that you can use to write letters on your computer is a type of software. The operating system (OS) is a software that manages your computer and the devices connected to it. Two well-known operating systems are Windows and Macintosh operating system. Probably your computer uses the Windows operating system. 19 LIÇÃO 10 Nouns: os…

forgone wages while you’re in school). By comparing these marginal benefits and marginal costs, you can evaluate whether the extra year is worthwhile. As another example, consider an airline deciding how much to charge passengers who fly standby. Suppose that flying a 200-seat plane across the country costs the airline $100,000.
