Name: Class: Date: ACE Chapter 4 review True/False Indicate whether the statement is true or false. 1. Today s Internet joins together networks of over 300 million computers, or Internet hosts, to create the world s second largest internetwork. 2. In 1989, ARPA commissioned ARPANET for research into networking. 3. The Internet is a combination of hardware, protocols, and software. 4. Software allows users to interact with the Internet to access information and services. 5. ISPs work as liaisons between Internet users and the telecommunications companies that own the backbones. 6.

An e-mail message sent from New York to Los Angeles passes from router to router until it reaches its destination. 8. Most dial-up service providers advertise an accelerated feature that boosts speeds up to five times that of a standard dial-up connection (to 280 Kbps). 9. A modem splitter is used for customers who use the cable for both television and the Internet. 10. Cable modem network lines are shared by neighbors, so if many neighbors access the Internet simultaneously, they might experience slower throughput. 11. Like a dial-up connection, and unlike a cable modem, a DSL line provides an always-on connection. 12. DSL is slower than cable service, but because it is a dedicated line rather than a shared line, you do not compete with neighbors for bandwidth. 13. Satellite service is slower than dial-up service but much faster than either cable modem or DSL. 14. The protocols for the Internet are the Transmission Control Protocol (TCP) and Internet Protocol (IP). 15. The Internet is a packet-switching network. 16. The Internet Protocol requires that all devices connected to the Internet have the same IP address. 17. IP addresses can be static, permanently assigned to a particular computer, or dynamic, assigned to computers as needed. 18. Domain names and IP addresses are managed by the Internet Corporation for Assigned Names and Numbers (ICANN) and can be purchased from accredited registrars. 19. Registering a domain name does not provide you with your own Web site, only with ownership of the name that you can associate with a Web site you have created and stored on a Web server with an assigned IP address. 20. It is anticipated that DHTML will gradually replace HTML as the primary markup language of the Web. 21. While creating static Web pages, those that simply present unchanging information, has become easy, today s professional-quality Web sites have evolved well beyond these basics. 1
Name: 22. JavaScript is similar to Java in that it provides functionality in Web pages through programming code that is embedded in an HTML document. 23.

Pervasive communications are the result of advances in wireless communications and Internet communications. 25. Asynchronous communication is not always possible as it requires all participants to be engaged in communication at the same time. Modified True/False Indicate whether the statement is true or false. If false, change the identified word or phrase to make the statement true. 26. Routers are the rules that are implemented in network software and hardware to establish connections between two or more computers to allow them to communicate. 27.

Search engines scour the Web with podcasts called spiders that follow all Web links in an attempt to catalog every Web page by topic. 34. Answering machines, voice mail, and e-mail are tools for synchronous communication. 35.
