A computer is a device that can perform computations and make logical decisions phenomenally faster than human beings can. Many of today's personal computers can perform billions of calculations in one second—more than a human can perform in a lifetime. Supercomputers are already performing thousands of trillions (quadrillions) of instructions per second! To put that in perspective, a quadrillion-instruction-per-second computer can perform in one second more than 100,000 calculations for every person on the planet! And—these "upper limits" are growing quickly!
Computers process data under the control of sets of instructions called computer programs. These programs guide the computer through orderly sets of actions specified by people called computer programmers. The programs that run on a computer are referred to as software. In this book, you'll learn today's key programming methodology that's enhancing programmer productivity, thereby reducing software-development costs—object-oriented programming.
A computer consists of various devices referred to as hardware (e.g., the keyboard, screen, mouse, hard disks, memory, DVDs and processing units). Computing costs are dropping dramatically, owing to rapid developments in hardware and software technologies. Computers that might have filled large rooms and cost millions of dollars decades ago are now inscribed on silicon chips smaller than a fingernail, costing perhaps a few dollars each. Ironically, silicon is one of the most abundant materials—it's an ingredient in common sand. Silicon-chip technology has made computing so economical that more than a billion general-purpose computers are in use worldwide, and this is expected to double in the next few years.
Computer chips (microprocessors) control countless devices. These embedded systems include anti-lock brakes in cars, navigation systems, smart home appliances, home security systems, cell phones and smartphones, robots, intelligent traffic intersections, collision avoidance systems, video game controllers and more. The vast majority of the microprocessors produced each year are embedded in devices other than general- purpose computers.
Grab your camera and get ready to Meet’n’Greet all your favourite Disney Characters for an encounter that’s unforgettable for all ages. To help you find them for a hug, an autograph and a photo, we’ve included when and where you can meet your favourite Disney Characters in the Disney Parks. Say cheese!
Enter a magical kingdom where you can sail with pirates, explore exotic jungles, meet fairy-tale princesses, dive under the ocean and rocket through the stars—all in the same day! Disneyland Park is a beloved Southern California destination where generations of families have made their Disney dreams come true. Opened in 1955, Walt Disney’s original theme park is divided into 8 extravagantly themed lands—Main Street, U.S.A., Tomorrowland, Fantasyland, Mickey's Toontown, Frontierland, Critter Country, New Orleans Square and Adventureland.
