Lesson 15: Using Archie (Another Search Tool) LEARNING OBJECTIVE: One will learn what Archie is and how to use it. Using FTP you can download all kinds of documents and softwareprograms from all over the world. The problem is that there arethousands of FTP sites. So how do you find that file on "how toimprove your baseball game?" that you have heard is out there. This is where you need the Archie program. Archie is another computer program that lets you type in searchwords to search for things. You can use Archie to search throughthousands of FTP databases all over the world for the file or filesthat contain the information you are looking for. Most FTP directories have a special file that is called an Index file. The Index file is a list of what information is contained in each file onthat particular computer. Think of an Index file like the index at theback of a book that tells you where in the book to go to find outabout a particular subject or to find out the definition of a particularword. The Archie catalogue maintains a list of about 1500 FTP sites wherealmost 3 million unique files are kept. These files contain over 200gigabytes of information. Archie can search this database for file locations when you give it akey word to search for. The Archie program will not actually get thefile for you, but it will tell you where you can find it. Once you knowthe file's name and location, you can use your FTP program to get it. There are three ways that you can use Archie: 1. You can use an Archie server that is running on your local Internet service provider's system. 2. You can use telnet to connect directly to an Archie server. Some Archie servers are: o archie@archie.ans-net o archie@archie-unl.edu o archie@archie.sura.net 3. You can use Archie by sending an e-mail letter directly to an archie server. To conduct an Archie search via e-mail, you should send an e- mail letter to the Archie server closest to you. Assuming you were interested in Apollo 13, in the body of your letter you would type: o Find Apollo 13 o Set mail to jamiec@mynet.com o Quit Archie servers are sometimes very busy, so sending an e-mail requestis sometimes faster than trying to search online. |

Lesson 18: Using IRC (Internet Relay Chat) LEARNING OBJECTIVE: One will learn how to use IRC. Internal Relay Chat (IRC) is a program that enables you to hold liveon-line conversations with people around the world. It is somethinglike a global CB radio network that you access via computer. It is afree-for-all place where people speak their minds to whoever willlisten. It is organized into channels that are based on topics. It is afairly new part of the Internet. IRCs allow you to chat in real time with people all over the world, just like you would having a telephone conversation - only this isonline. It's like having a telephone conference call with people in Russia, Mexico, and Australia - all at the same time! One of the main attractions of IRC is that you can create and control your own channels. You can have private online chats with a groupof friends, like getting together at someone's house - only this houseis on the Internet in cyberspace and your guests may be from all overthe world! If you are not using one of the Internet programmme that supports IRC, you can get both Windows and Macintosh shareware programs fromseveral FTP sites on the Internet. After you install the program andconfigure it - following the instructions that come with the program -you must now choose your nickname. This is the name (not yourfull, real name) by which you will be known on the chat channels. Then you call up your Internet provider as you normally do and logon to an IRC Server. (There are many books on the market that can provide lists of IRC servers.) It takes a little getting used to - much of what you see will look likegibberish at first. Do not worry about it. The part that you need to understand will soon become clearer the more time you spendon it. You might find a book that has an example of what you mightsee to help you understand it. Basically, after you log onto the Internet and join a chat (channel), you type something on your computer, and all the other peopletuned into your channel can see it instantly. At any one time, hundreds of channels are buzzing with chatter. You can either joinone of them or create your own. |

Lesson 19: Expressing Feelings and Emotions on the Internet LEARNING OBJECTIVE: One will learn some of the ways people convey feelings, emotions and other things that are difficult to express on the Internet. One of the most interesting things about the Internet is the way people convey feelings and emotions. Because face-to-face electronic chat is still somewhat of a dream for the general public, creative humans have developed their own set of lettersand symbols that represent emotions, feeling, and other things that are tough to express. Those familiar with techno-speak call these symbols emoticons (emotional icons) or simply smileys. Emoticons are lots of fun. You can read most of them by tilting your head 90 degrees left and looking at the symbol. A smile (sideways) looks like this: :-) Neat, eh? Here's a hug: (01 Not happy: :- ( How about: [:-) Wearing a Walkman !?! Or how about designing a list of famous people. Can you guess the following? *<:-) Santa +O<:-) The Pope |
