Surfing the Net-which wave to ride?
The Internet, or "Net," is a basically a complex collection of networks. The Net is also referred to as the Web, the World Wide Web, WWW, [W.sup.3], the information superhighway, cyberspace, and a number of other slang terms. It is a large network of networks connected by fiber optic cables, satellites, phone lines, and other communication systems. The Net currently connects more than 30 million users and businesses all around the world. It links 30,000 computer networks in over 100 countries, and that number is dramatically increasing every day. The Internet is very versatile, powerful, and useful.
On the Internet, you can find a tremendous amount of information and a multitude of services that can enrich both your professional and personal life. Most people use the Internet to send and receive electronic mail (e-mail), download or upload files of information or data, search the numerous databases for information, join "chats" or electronic discussions, play games - both alone and with another user or users, and run programs on remote computers. It is also a rich marketplace for both products and services.
In Private Hands
The Internet, developed by the U.S. Department of Defense, started as a network to link scientists and academicians around the world. Today, however, the Internet is maintained by private industry - not by the government. It has evolved into an exciting, easy, and inexpensive way for people to communicate across the globe. No single person, corporation, institution, or agency owns or operates the Internet, although individuals, corporations, educational institutions, and government agencies own and operate the smaller individual networks that comprise the Internet. No one screens or regulates the data, and there are no rules about the nature of information or where it is stored. So, the quality of the data varies greatly. In recent years, groups have been formed to self-regulate the Internet in an attempt to prevent the government from doing so.
Many people use slang terms when they refer to the Web. Some terms that you might encounter, and their meanings, are listed in the accompanying "Web Slang" glossary.
"Surfing the Web" is a slang expression for browsing, or looking around the Internet. There are many ways to gain access to information on the Web. But, first, you must get on line which requires a computer and a modem hooked up to a telephone line.
Browser, or Service?
Often, your access route to the Internet will depend on your needs. You may purchase a Web browser for access to the myriad information sources of the Web, or you may subscribe to an on-line service. An easy, quick way to "get onto" the Web is to purchase a Web browser such as Netscape Navigator. Web browser software usually includes the communications and utility software you need to get on line and onto the Net. Other Web browsers include: Cyberjack, Chameleon, InternetSuite, Internet in a Box, Internet Membership Kit, NetCruiser, GNN, Pipeline, and Sprynet.
On-line services provide information and services to members for a fee. Some of these include: at-home banking, e-mail, shopping at home, news and weather, travel information and reservation services, investment services, and stock market information. Some of the major on-line services are:
America Online - provides news, weather, shopping, finance, travel information
Prodigy - provides news, weather, shopping, finance, travel, numerous family services
CompuServe - provides mostly business-oriented services
Microsoft Network - provides news, weather, shopping, finance, travel information
Delphi - provides Internet access and services
Genie - provides news and database information - mostly technical and professional in nature
Imagination - provides games and entertainment
eWorld - provides general services, mostly for Apple and Macintosh users
Dow Jones - provides finance and business information
Ways to Communicate
The various ways to communicate with others on the Internet include e-mail and bulletin boards. E-mail, or electronic mail, is similar to sending or receiving messages or memos by mail, but they are transferred over cable or phone lines between computers. Users are not required to use the same network. Many organizations provide e-mail systems for their employees. E-mail is also offered by service providers such as Prodigy.
Bulletin boards, newsgroups, and discussion groups provide a way to interact with other users who have common interests. Thousands of subjects are discussed on the Internet via bulletin boards, including politics, business, the environment, music, sports, religion, and more. There is probably a bulletin board set up for just about every topic imaginable. Bulletin boards often serve as a form of electronic club for a specific purpose. Many computer vendors set up bulletin boards to provide on-line service for their products. A number of organizations list job openings and company information on the Web, and many prospective employees list their resume on the Web.
Linking and Downloading
A user who attempts to gain access to information on the Web will encounter one of three possible outcomes: the link may be successful, busy, or closed. When a link is successful, the user will be connected to a host that will transfer data to the computer and display the data on the screen. If too many people try to reach the same host at the same time, the host might be busy, and some users won't be able to get through. Sites that have been removed or renamed are considered to be closed or abandoned. The amount of time it takes to connect or "link" to a host depends on the volume of traffic.
The address of the host is a uniform resource locator, or URL. It is made up of many parts, all indicative of the location and type of host. A URL is composed of a protocol identifier, a server address, and a file pathname. For example:
http:// = protocol identifier
www.netscape = server
com = type
home = folder
welcome = filename
html = extension
To obtain files of data from a host server on the Internet to your computer, you need to use File Transfer Protocol, or FTP. FTP provides a way to link to a computer elsewhere on the Internet, view its directories, and transfer files to and from your computer. A protocol is a set of rules or a standard that has been set up to allow computers to communicate. FTP will allow computers to transfer files efficiently. You can quickly recognize an FTP site by its URL, which begins with ftp://, http://, or gopher://.
Downloading, or transferring files from the Internet to your personal computer, is very useful. There is myriad information on the Web - some free, some available for a fee. You may move this information to your computer for your own personal use. Included are games, clipart, sounds, video clips, utility software, reference information, research information, and more. There is also an on-line shopping service which allows users to purchase items or services through their personal computer - usually at a discount.
The Internet does seem a bit overwhelming the first time you attempt to go online. There is much information, and there are many sites to visit. But, once you get a feel for the way it works, you will find the ride exciting. Enjoy the surf.
