.. ent day people are telecommuting over the Internet, allowing them to choose where to live based on quality of life, not proximity to work. Many cities view the Internet as a solution to their clogged highways and fouled air. Schools use the Internet as a vast electronic library, with untold possibilities. Doctors use the Internet to consult with colleagues half a world away. The Internet even offers a single Global Village; it threatens to create a 2nd class citizenship among those without access.
As a new generation grows up as accustomed to communicating through a keyboard as in person, life on the Internet will become an increasingly important part of life on Earth. The Age of the Internet has arrived. How It Works In Present Day The Internet works by a number of connections one leading to a bigger one and then somehow finding where it wants to be. So how does it do this? First it begins at the users PC where that is equipped to send and receive all variety of audio and video. From there is the data goes out through the PCs communication to connect the Users to the “Local Loop” which is the Internet service provider such as AOL or some other online provider.
In there the system decipher what kind of data is being sent and at this location it tells the data what type of data it is and where to go. Examples of the different kinds of data are examples of this are Domain Name Server, E-mail, and newsgroups. From there it is sent to the ISP backbone which interconnects the ISP’s, POPs, AND interconnects the ISP to other ISP’s and online content. At this location the data is routed to the desired location and the online content they user was looking for is found. The data is then sent back through the system to the original user. The information that is on the data coming back could have came from a wide array of sources such as books, finical markets, embedded chips or even made up by someone trying to fool the user.
Many Things To Do Over The Internet There is a plethora of things to do over the Internet and it has made a huge impact of society. Over the Internet people can communicate through chatting or email, the can learn just about anything they want to on the vast number of websites dedicated to just about everything, a person could purchase something over it by the means of e commerce, and they can even listen to radio stations from far away through their computer. This is just a short list of the many things that could be done over the Internet but now this paper will discuss some of the main features of the Internet. E Commerce E commerce is doing business over the Internet. This is done by first the user logs onto the companys site and searches around on it until they find the desired product they want to buy.
Then usually a from will come up and the user will enter vital finical information by either putting down his credit card number or other means of money. Then the data is encrypted and sent over the Internet. This is dangerous because if the data is not encrypted enough a person may be able to break the encryption and obtain the purchasers finical information. This is one of the major concerns of the purchasers and why some people do now buy things online. When the data is transmitted safely to the seller then the transaction is a complete and the item is sent to the user by some from and the purchasers finical account information is updated.
The negative sides of this type of business is that since many people are afraid of someone steeling their information and because of the time shipping the product to the purchaser the people do not purchase online. Even though some people think this there is a tremendous amount of people that do their business over the net and e commerce has become a huge player in the finical environment. E Mail E-mail is the electronic exchange of information. An e mail or electronic message is just like a letter you can send in the mail but instead of the user getting a hard copy, the user gets a soft copy. It works by first a message sender uses mail software, called a client, to compose a document, possibly including attachments such as tables, photographs or even a voice or video recording.
System software, called Transmission Control Protocol (TCP), divides the message into packets and adds information about how each packet should be handled-for instance, in what order packets were transmitted from the sender. Packets are sent to a mail submission server, a computer on the internal network of a company or an Internet service provider. Internet mail addresses attached to each message are in the form “[email protected]” –one specific example being “.” The multipart domain name denotes a top-level domain (“.com”) following the second-level domain (“sciam”). A message is delivered to an individual or a group by the mailbox name (“editors”). Then it goes to the mail submission server which converts the domain name of the recipient’s mail address into a numeric Internet Protocol (IP) address.
It does this by querying domain name servers interspersed throughout the Internet. For example, the mail submission server can first request from the “root” name server the whereabouts of other servers that store information about “.com” domains. or it can then interrogate the “.com” name server for the location of the specific “sciam.com” name server or a final request to the “sciam.com” name server provides the IP address for the computer that receives the mail for sciam.com, which is then attached to each message packet. Next it is sent to routers that are dispersed throughout the Internet and read the IP address on a packet. It then relays it toward its destination by the most efficient path and because of fluctuating traffic over data lines, trying to transmit a packet directly to its destination is not always the fastest way.
The packets of a single message may travel along different routes, shuttling through 10 or so routers before their journey’s end. It eventully makes it to its destination mail server places the packets in their original order, according to the instructions contained in each packet, and stores the message in the recipient’s mailbox. The recipient’s client software can then display the message. E-mail has revolutionized the way people communicate. Now instead of waiting a day or two for the post office to mail something a e mail can get it to the desired location just about anywhere in the world in seconds.
A sender can also now send files over within an e mail as an attachment. One of its best qualities is that for the most part e mailing is free. The only costs that might be incurred are though the service provider or some other accessing fee.
