	your service from a retail ISP. Your ISP takes its profit and buys
	bulk services from a bigger provider who does the same thing. This
	may happen a couple of times until there gets a point where there are
	places where the big providers all connect together and communicate
	with each other. There are only a few of these in each area of the
	world and they pay a fee to connect at these points. The connection
	points are connected together by international providers, so that if
	you connect to the Internet at one point, you can get anywhere in the
	world.
	2.2. Who Runs the Internet?		There is a large variety of activities that users can do on the
			Internet. These activities include surfing, searching, sending mail,
			transfering programs and documents, chatting, and playing games.
	The Internet is operated as a cooperative effort among the ISPs,		SURFING
	software companies, volunteer organizations, and a few facilities
	that tie the whole thing together. The ISPs and software companies
	are completely independent and most of them compete with each other.
	The ISPs agree to connect to each other and transmit information
	following an established set of rules (protocols). The software
	companies agree to manufacture programs (such as email or web
	browsers) that also follow protocols. These protocols are developed
	by a group of volunteers (Internet Engineering Task Force IETF) that
	come together regularly and discuss how the Internet is running and
	how to standardize new services.
	But, there are things that must be unique in the Internet, just like		Surfing is one of the most popular Internet activities. To surf, a

	a wide variety of computers.		By clicking on one of these links the user is then connected to that
			information. This information may be at the same location or may be
			at a different location. This new information may, in turn, have
			links to other information. So just like a footnote or reference in
			a print publication, links can be used to find related or non-related
			information.
	2.3. What Can I do on the Internet?		SEARCHING
	There are a variety of applications and activities on the Internet.		Searching involves using a special program known as a seach engine.
	These include the ability to surf, use search tools, send mail,		There are several of these engines that are located at various search
	transfer programs and documents, and chat.		sites. The popular web browsers have location information about
			these search sites. Searching is similar to using a card catalog in
			a library. Just as a person would look up a topic in a card catalog
			and find one or more references to that topic with library location
			information, a search engine provides the user with a list of sites
			that may contain relevant information. This list is actually a set
			of links to these sites so that all the user has to do is click on
			the link to go to the location. Just as different library card
			catalogs will contain different reference cards, different search
			engines will provide different reference lists.
	Surfing is one of the two most popular activities. To surf, a user		E-MAIL
	uses a program known as a web browser. The web browser enables the
	user to connect to a location that contains information. From one
	location a user can follow various links by clicking on them to
	explore the Internet. Like following a footnote or reference in a
	print publication, links can be used to find related or non-related
	information.
	Typically surfing begins by connecting to a site that contains a		E-mail is another very popular activity. It is very similar to

	Another application and activity known as chat takes place with		CHAT
	another person or persons who are also on the Internet. Chatting is
	very similar to going to a party. Just as people congregate in small
	groups and discuss things, chatters meet in chat rooms to discuss a
	topic. Chat rooms are generally sponsored or operated by an
	organization that has an interest in the topic area. For example, an
	online news organization would have a chat room for chatters to
	discuss current events. To chat one person writes a message which
	can be read, as it is being written, by the others who can respond to
	it in turn. Persons who enter a chat room but dont enter the
	discussion are said to be lurking. Chatters come and go to chat
	rooms the same way people move about groups at a party.

			just as at a party where some people never say anything, so there may
			be people in the room who are just listening. Also, just like at a
			party, some people may portray themselves to be someone different
			than who they really are. Lastly, remember that chatters come and go
			to chat rooms the same way people move about groups at a party.
			GAMES
			Some people use the Internet to play games. These games can be role
			playing games, action/adventure games, or online versions of old
			standbys like chess. Some games require the user to purchase a copy
			of the game and install it on their computer, while others are played
			by going to a game site. Just like other forms of game playing,
			Internet game playing can be challenging, entertaining, and an
			enjoyable social experience. Don't be afraid to have fun.
			OTHER ACTIVITIES
			Other popular activities include electronic shopping, banking, and
			investing. Many retailers describe and display pictures of their
			products on the Internet enabling people to buy on line. Shopping
			also includes purchasing services such as an airline ticket or
			ordering groceries. Many banks allow people to transfer funds, check
	available funds, pay bills and other such activities while on the		available funds, pay bills and other such activities while on the

			protecting your information. If you are in doubt about how your
			information will be protected, don't use your credit card at that
			site.

	addresses. IP addresses are used to move (route) the message along
	the best path to the destination. Thus the name has to be translated
	into an IP address. The name-to-address mapping system called the
	Domain Name System (DNS) does this. Once the address has been
	determined, a set of protocols called routing protocols find the best
	path to the destination. Then an activity session is created between
	the source and the destination computer. The e-mail protocol checks
	the destination to make sure that it will accept the message.
	Finally the message is transmitted. As it moves from the source to
	the destination it may cross several networks that belong to several
	ISPs. All of this activity takes place within the time it takes to
	read this paragraph!

			managing the email system and follows rules that have been
			established by the company providing the e-mail service. Sometimes
			the name portion of the e-mail address is referred to as a mailbox.
			The portion to the right of the "@" sign is the name of the computer
			system that is providing the e-mail service. This name is usually
			the name of the company that owns the computer system followed by a
			"dot" and an abbreviation that represents the "domain" or group of
			names which the organization falls under. Examples of these "top
			level" domains are "edu", "com", and country codes such as "fr" for
			France and "jp" for Japan. When an e-mail is sent the portion of the
			address to the right of the "@" sign is used to find the destination
			computer of the email.
			URL
			A Uniform Resource Locator (URL) is commonly used to identify a
			computer that provides world wide web service. It usually looks
			something like "http://www.newspaper.com". This address also
			consists of two parts. In this case the two parts are separated by
			the "//". The portion to the left means find the world wide web
			service that is located at the computer identified to the right of

			is providing the world wide web service. Its name is composed of
			parts that are similar to those described for the name of an email
			computer. Sometines the portion of the right contains additional
			information that identifies a particular document at the web site.
			For example, http://www.newspaper.com/sports/article1.html would
			identify a specific article in the sports section of the newspaper.

			E-mail in particular can lead to misunderstandings between people.
			Users should remember that the reader only has the text to determine
			what is being said. Other conversation cues such as "tone of voice"
			and body signals like winking are not present in the text. Because
			of this, users of the Internet have developed cues to put in the
			text. Text techniques such as capitalization and symbols known as
			emoticons (also called "smilies") are used.
			A typical smiley looks like this :-)
			Additionally, acronyms have evolved over time (for example IMHO - In

			searching. Use keywords like "netiquette" and "emoticon" with your
			search engine to find more information.

			Computers take turns sending and receiving information. When a
			computer is sending information, it is known as the "source"; when it
			is receiving information, it is known as the "destination." (The
			same computer can be both a source and destination at different
			times. This is especially clear when one thinks of sending and
			receiving e-mail.)
			Every computer on the Internet has a unique Internet "address" that
			identifies it from among the millions of computers. The Internet has
			specialized computers between the source and destination located at
			network inter-connection points. These computers are known as
			"routers." The routers understand how to use a computer's address to
			appropriately point information from one computer to another over the
			Internet.
			In an exchange of information the following occurs:
			* The source finds the address of the destination.
			* The source contacts the destination and says "hello".
			* The destination responds back with a "hello" of its own.
			* The source tells the destination that it has information to
			send.
			* The destination tells the source that it is ready to receive the
			information.
			* The source breaks the information into small pieces called
			packets and sends each packet on its way to the destination.
			* The routers guide each packet to the destination.
			* The destination takes the packets and puts them back together to
			form the information.
			* The destination tells the source that it has received the
			information and asks the source if it has anything more to send.
			* If the source says no, the destination will say "good bye"
			unless it has something to send back. If it does, it will break
			the information into packets and send them.
			* Once both end users are done "talking" they say both say "good
			bye".
			Clearly our simplified introduction to this section did not explain
			many steps in this process, such as how a computer discovers the
			address of another computer or how packets are divided and
			reassembled. Fortunately, these are specifics that people using the
			Internet never really need to deal with!
			2.6 Who Runs the Internet?
			No one. The Internet is a cooperative effort among Internet Service
			Providers (ISPs), software companines, volunteer organizations, and a
			few facilities that tie the whole thing together. The ISPs and
			software companies are completely independent and most of them
			compete with each other. The ISPs provide internet service to people
			much the same way that they obtain telephone service from a telephone
			company. ISPs agree to connect their networks to each other and
			transmit information following an established set of rules
			(protocols). The software companies agree to manufacture programs
			(such as email or web browsers) that also follow protocols. There
			are other organizations that keep things straight. Some assign
			Internet addresses in much the same manner as telephone numbers are
			assigned, others keep track of names used by Internet users and
			groups, and a large volunteer organization called the Internet
			Engineering Task Force (IETF) develops the protocols computers follow
			to make network communications succeed.
	3. Security Considerations		3. Security Considerations
	It is important to realize that not Internet user is a good netizen.		The question "is the Internet secure?" can be a confusing one for
	Therefore, users should learn to protect themselves. The IETF has		people, who will hear many assurances that it is secure and many
	published several RFCs that provide security information and		scary stories saying it is not secure. There are a few basic rules
	guidance. Additionally, users can protect themselves from sites and		of thumb to remember that will address most concerns.
	documents that have unwanted content by using baby sitting software.
			First, make it a rule never to share account passwords with anyone.
			Learning a password is the easiest way for someone to break into a
			system. Most people feel that their files are not that interesting
			to anyone, but someone may be able to get a foothold from one
			innocuous account to other places in the same computer system. Many
			good security practices can be found in the Users Security Handbook
			[FYI 34, RFC 2504].
			Second, understand that there are means for people to track the
			information a user sends via email, the files one downloads, and the
			sites visited on the web. The system administrators and network
			engineers who oversee a sites' computers require access to
			information that an individual may think is secret. In practice, no
			responsible system administrator or network engineer will violate a
			person's privacy out of personal curiousity. However, if someone
			less legitimate attains illegal access to a system, they also will
			have access to this information. This situation is not a problem for
			most people, but it should be understood that things like email sent
			a year ago or a log of users web pages browsed may still exist in
			some system's backup archive tape and can be easily resurrected and
			published widely.
			Third, before giving personal information over the Internet, such as
			filling in a form on a Web page, users should realize that there is
			no assurance of confidentiality or privacy. It could be compared to
			faxing such information to a party that you've never dealt with
			before. While many organizations on the Internet are responsible
			with information received via the web and email, this cannot always
			be determined in advance.
