A) Make summary of the text.Could the Internet collapse? Here's __ good news ─ a total collapse of the Internet would be almost impossible. The Internet isn't __ magic box with an on/off switch. It's not even __ physical thing. It's __ collection of __ physical things and it's constantly changing. The Internet isn't __ same entity from one moment to __ next ─ machines are always joining or leaving __ Internet. It's possible for parts of __ Internet to go __ offline. In fact, this happens all __ time. Whether it's __ particular server that crashes and needs to be rebooted or replaced or __ cable under __ ocean gets snagged by __ anchor, there are events that can disrupt Internet service. But __ effects tend to be isolated and temporary. While there is such __ thing as the Internet backbone─ a collection of cables and servers that carry __ bulk of data across various networks ─ it's not centralized. There's no plug you could pull out from __ socket or a cable you could cut that would cripple __ Internet. For the Internet to experience __ global collapse, either __ protocols that allow machines to communicate would have to stop working for some reason or __ infrastructure itself would have to suffer massive damage. Since __ protocols aren't likely to stop working spontaneously, we can rule out that eventuality. As for the massive damage scenario ─ that could happen. __ asteroid or comet could collide with __ Earth with enough force to destroy __ significant portion of the Internet's infrastructure. Overwhelming __ gamma radiation or electromagnetic fluctuations coming from __ sun might also do the trick. But in those scenarios, __ Earth itself would become __ lifeless hulk. At that stage it hardly matters whether or not you can log in to MySpace. The positive way to look at this is to realize that __ men and women who helped design __ Internet created __ amazing tool that's remarkably stable. Even when sections of __ Internet have __ technical hiccup, __ rest carries on with __ business as usual. While __ collapse of __ Internet would be __ catastrophic event, it's not one you need to worry about. (By Jonathan Strickland) Read this e-mail.
