1.The influence of the InternetThe influence of the Internet has caused a change in the way we shop, communicate, and learn.Prior to the Internet, everyday tasks such as banking, paying bills, and shopping took time outside the home. With the Internet, online banking allows people to keep their personal finances on track twenty-four hours a day. While this is nothing new, banks did offer phone services to do the same functions, the fact that online banking can now be combined with online bill paying, late payments are quickly becoming a thing of the past. Even online shopping can save time and energy. Shopping for the latest trends in clothes? Hop on line and pick outfits from your favorite stores. No more going to the mall, finding a parking space, then not being able to find your size. Online shopping gives more options and real-time inventory of items. A mall store may have limited space to display all the trends, but an online store is only limited by the size of their imagination. Online shopping has even progressed into the supermarket realm. Sit at home on a Thursday evening and order food for your Saturday backyard bar-ba-que for delivery on Saturday morning. No more pushing a cart around a big box store, and lugging heavy plastic bags to you car. Door to door delivery of groceries means you never have to go to the store again.The Internet has also closed the gap for many families separated by the miles. While the US Postal Service has progressed since the days of the Pony Express, the Internet has made stamps and phone calls nearly obsolete. During World War II, letters to and from troops were censored and shrunk to nearly microfiche size. With all the processing required, letters often took weeks or months to arrive. Today, a quick email takes seconds to convey feelings of fear and joy to love ones around the world. As the Internet becomes utilized more for emails, emails themselves have become more sophisticated. Pictures and short movies now zip around the world at lightning speed. Want to show the newest member of the family to Grandma in Florida? Take some video and attach it to an email. For less then the cost of a plane ticket, she can count all the fingers and toes herself.The Internet is probably most famous for the ability to spread information, fact or fiction. We were once limited to news editors of a local paper, then to national cable news. Now anyone can search the globe, visit local papers in foreign countries, and see the views of all sides. This ease of information has also brought with it a large amount of hoaxes, money schemes, and fallacies. Internet websites offering quick money, instant weight loss, and Nostradomises predictions sit side be side websites providing legitimate health information, historic facts, and online stock trading.The Internet has also helped increase the entire computer hardware industry. To compete in the latest online gaming, the fastest computers are often needed. The hardware industry constantly pushes bigger, faster, and more expensive equipment, even to people that already own a computer. The hardware industry may push speed of hardware as a reason to upgrade, but the average Internet user will always be limited by the speed of their Internet connection. Dial-up Internet access is the same speed whether using a four year old slow computer, and the latest model from the Dells and Gateways of the world.2.Uses of the Internet Companies, individuals, and institutions use the Internet in many ways. Companies use the Internet for electronic commerce, also called e-commerce, including advertising, selling, buying, distributing products, and providing customer service. In addition, companies use the Internet for business-to-business transactions, such as exchanging financial information and accessing complex databases. Businesses and institutions use the Internet for voice and video conferencing and other forms of communication that enable people to telecommute (work away from the office using a computer). The use of e-mail speeds communication between companies, among coworkers, and among other individuals. Media and entertainment companies run online news and weather services over the Internet, distribute music and movies, and actually broadcast audio and video, including live radio and television programs. File sharing services let individuals swap music, movies, photos, and applications, provided they do not violate copyright protections. Online chat allows people to carry on discussions using written text. Instant messaging enables people to exchange text messages; share digital photo, video, and audio files; and play games in real time. Scientists and scholars use the Internet to communicate with colleagues, perform research, distribute lecture notes and course materials to students, and publish papers and articles. Individuals use the Internet for communication, entertainment, finding information, and buying and selling goods and services4.1.moderate suggestionMost of us use computers to search for more information about the interesting problems on the textbooks, about Iraqi wars and about Oscar. Some of us use computers to do some drawings, to make up interesting flashes. And some of us use them to play games. If we are tired and want to take a short rest, playing games for a while is OK. But its forbidden that we spend hours and hours on the games. There is also someone using computers to talk with people in the Internet and even falling in love with him or her. The Internet is not a real world and we cant tell lies from truths. So falling in love with somebody on the Internet is not safe and is bad for our study. We should keep ourselves out of it. As is generally known, the computer can do a wide range of work, including complex computation and analyses. People now also use it as a teaching aid in designing. An infinite variety of software can be put into the computer, which explains why it is so powerful. There is, however, one thing which we should bear in mind: that the computer cannot think but man can. So there need not be any fear that someday the computer will control us and all we should expect is try our best to bring it to perfection. A computer age is not a pipe dream and there will come a day when most of our needs can be met by this wonderful machine.5.the disadvantages of internet and computer Internet makes people passive by stopping them making their own entertainment. So much so that when there is a breakdown or jam, people may find that World Wide Web turns into World Wide Wait. What is worse, some children have accessto the scenes of violence and sex. Apart from these, it can be affected by viruses(病毒) and hackers(黑客). We should handle its problems, meanwhile we should exploit its potential as well. With proper management of Internet people ought to experience more fruits of the information revolution. All the wisdom of the ages, all the information that has enlightened mankind for centuries, should be available to us with the healthy development of Internet6.the developement of computerComputers take numerous physical forms. Early electronic computers were the size of a large room, consuming as much power as several hundred modern personal computers. Today, computers can be made small enough to fit into a wrist watch and be powered from a watch battery. Society has come to recognize personal computers and their portable equivalent, the laptop computer, as icons of the information age; they are what most people think of as a computer. However, the most common form of computer in use today is by fa
