The World of Computers -- Ch. Inside the Computer -- Ch. Networks and Networking: Linking the World -- Ch. The Windows Environment -- Ch. Graphics and Multimedia; Tickling our Senses -- Ch. Computers in Society. Computers often referred to as hardware are controlled by software i. Computer use is increasing in almost every field of endeavor. Computing costs have been decreasing dramatically due to rapid developments in both hardware and software technologies.

Computers that might have filled large rooms and cost millions of dollars a few decades ago can now be inscribed on silicon chips smaller than a fingernail, costing a few dollars each.

Those large computers were called mainframes and are widely used today in business, government and industry. Fortunately, silicon is one of the most abundant materials on earthit's an ingredient in common sand. Silicon chip technology has made computing so economical that about a billion general-purpose computers are in use worldwide, helping people in business, industry and government, and in their personal lives.

Over the years, many programmers learned the programming methodology called structured programming. You will learn structured programming and an exciting newer methodology, object-oriented programming. Why do we teach both? Object orientation is the key programming methodology used by programmers today. You will create and work with many software objects in this text. You will discover however, that their internal structure is often built using structured-programming techniques.

Also, the logic of manipulating objects is occasionally expressed with structured programming. You are embarking on a challenging and rewarding path.
