Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 22 to 28.

The Internet started out as a limited network called the ARPANET (Advanced Research Projects Agency Network). It was a network of computers that allowed communication even if computer became non-functioning. It was the academic and scientific community that adopted Internet, using a protocol called TCP/IP. TCP/IP allows a number of different network computers to be connected together. This is called the Internet. The Internet allows the creation the World Wide Web or the Web for short. The Web consists of Internet sites that allow data to be shared by others. Aside from making the Web possible, the Internet also makes e-mail, chat rom and file-sharing and telephoning possible. It even allows people to watch media and play games.

The Web can be read in a browser. A browser is simply a software program that uses HTTP (Hyper Text Transfer Protocol) data transmission. This will allow you to view Web pages. HTTP let you browser read the text, graphics, animation, video and music that are on the Web page. It also enables you to click on a link on the page using the mouse. The links on a Web page that guide you to go from one Web page to another are called hyperlinks. A Web page usually contains many hyperlinks so that you can “browse” the Internet. It is much like reading a book. You can go from page to page and get new information. One example of a browser is Internet Explorer. In the address box of your browser, you can type in an address called a URL for “uniform resource locator”.

To be able to use the Internet, you must have a computer with an Internet connection and software that lets you view that Web pages. Internet connection is called a dial-up connection. It needs the use of your telephone to connect your computer to an Internet service. A faster type of connection is called broadband. This requires a cable or some other equipment. If you turn on the computer with a broadband connection, it connects you the Internet at a time.
