The Wild and Woolly Web
Like humans, computers are subject to attack by outside forces. With care, though, you can protect your PC from contagious ailments.
As long as networked computers have existed, programmers have exploited their combined power to accomplish difficult computational problems. For instance, computer-animated movies like Toy Story were not rendered on just one machine. The animation was done on what is called a "server farm" of dozens of networked computers.
