Information - Web - General Domain Names What is the Domain Name System? The Domain Name System (DNS) helps users to find their way around the Internet. Every computer on the Internet has a unique address 굳t like a telephone number 稩ch is a rather complicated string of numbers. It is called its "IP address" (IP stands for "Internet Protocol"). But it is hard to remember everyone's IP address. The DNS makes it easier by allowing a familiar string of letters (the "domain name") to be used instead of the arcane IP address. So instead of typing 192.0.34.65, you can type www.icann.org. It is a "mnemonic" device that makes addresses easier to remember. Translating the name into the IP address is called "resolving the domain name." The goal of the DNS is for any Internet user any place in the world to reach a specific website IP address by entering its domain name. Domain names are also used for reaching e-mail addresses and for other Internet applications.

POP mails - Point of Presence email storage facility (also known as Post Office Protocol) OK...simply put a POP mail box is somewhere on the internet where your emails are stored until you decide to download them. Anybody who can send emails will already have a POP box. This is usually with your dialup provider - the company you use to connect to the internet with (i.e. aol.com). So....why do you need one (or 5). Well lots of people like the fact that they can store their emails on our servers instead of somebody else's. PPP Internet access required to read or send e-mail. This means you will need to have a dial up account to connect to the Internet with your local ISP (Internet Service Provider). You will also need to use your ISPӍTP address to send mail. When setting up a program to get and receive mail, you should be able to put our address in the POP setting and your local ISPࡤdress in the SMTP setting. There are two versions of POP. The first, called POP2, became a standard in the mid-80's and requires SMTP to send messages. The newer version, POP3, can be used with or without SMTP. IMAP Something newer than POP is IMAP, for Internet Message Access Protocol, a protocol for retrieving e-mail messages. The latest version, IMAP4, is similar to POP3 but supports some additional features.

IMAP was developed at Stanford University in 1986. STMP SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail. However, since it's limited in its ability to queue messages at the receiving end, it's usually used with one of two other protocols, POP3 or Internet Message Access Protocol, that let the user save messages in a server mailbox and download them periodically from the server. In other words, users typically use a program that uses SMTP for sending e-mail and either POP3 or IMAP for receiving messages that have been received for them at their local server.

Servers / Clients The data used on the Internet is delivered by servers. There is an email server to handle your email, an FTP server to transfer files, and a Web server that delivers webpages so that you can view them on your computer. Your browser is the client, and the remote computer is the server. It is only by convention that these servers are named www, but they can be named anything. Lately, there have been websites that eliminate the WWW and just use the domain name. It is the http:// that tells your browser it is Web traffic. It then asks the server for data on a specific port. It is presumed that if you are using a browser, you are using Web traffic. Http defines how to format and transmit the data and what actions the Web servers should take in response to various commands. |
