Internet Service Provider

     An internet service provider (ISP) connects you and/or your stuff to the internet cloud which accesses the outside world. Many people consider this a form of magic, but like anything else, it's not once you know how.

     The purpose of this document isn't to teach you how to be an ISP, but to educate you on the basics so you know what you are asking for.

     Who is the best ISP? The best is, whoever you find that takes care of your needs. Your ISP should be up and running 100% of the time. They should not be constantly over-subscribing their services.

     Should we choose the biggest? We all know the biggest can have some advantages, but the smallest can make it up in versatility. From the largest to the smallest, some are good and some aren't. Get a good one. If you count on the internet for your income, a little extra cost could save you a money and reputation in the long run.

Modem Access

Basic internet service for most people starts with modem access. The ISP is connected to the internet with a big line and distributes internet to individuals through smaller lines. The phone line is where most folks start out. The price is reasonable and it gets you into everything on the internet.

Unfortunately, phone lines have been limited to 56k for internet access. How much speed you actually need depends on what you do. If you just check your email with text only, you really won't notice much difference with different speeds. If you download huge files, you'll want the fastest download speeds you can afford.

Email

     Email is one of the most popular services of the internet. Most people have some form of email. It is the one thing that defines us while we visit the cyber world.

     If you just have web access, your email address domain will be shared by the ISP. In other words, you are using their domain. If you have your own domain, your email address can be through your own domain.

     Email is actually accomplished in two stages. One is sending, the other is receiving.

Email Servers

     When you send an email to Aunt Mildred in New Jersey, the sending server (SMTP) first determines where Aunt Mildred's server is located and sends the message to the server in New Jersey. That server in turn, looks at the email address and determines which mail slot to put the message in.

     Later, when Aunt Mildred checks her email, she logs into her email server (POP3). The server then delivers her email messages, including yours.

     Now, let's say Aunt Mildred replies. Her email server (another SMTP) has to figure out where your server (another POP3) is and send the message to it. Now, your email server must determine which mailbox to place the message in.

     Then, when you log in to the email server, you get Aunt Mildred's email message.

High Speed Access

     Once you reach the point where 56k just doesn't cut it, you are going to want to take the next step and go high speed. Many technologies exist. Most choices are limited by availability. Very few areas include everything.

     The speed options also include upload and download speeds. The upload speed is usually about 10-50% of the download speed. This works great for most people, because surfing involves short requests for larger downloads. If you are running servers, you want faster upload speeds.

     Another aspect of speed is guaranteed bandwidth. If an ISP has 1000k of bandwidth and distributes to 50k lines, how many lines can they sell? Basic math says 20, but since everyone isn't flying full speed constantly, they could increase that number without degradation.

     If your ISP grossly over-subscribes, your bandwidth can decrease dramatically. During prime time hours, this could be the slowest internet access there is. Really not worth the money.

     Frame Relay is commonly known as a T1, T3 or 56k Frame. These have been around forever and are pretty reliable. They are also expensive. The upload/download characteristics of a frame relay line are usually balanced. The phone companies tend to understand these and support them better.

     The DSL technologies are still relatively new. They are provided through regular phone lines. Many DSL's even allow you to talk on the phone while you surf. DSL does require your physical distance from the phone company equipment to be within the supported area.

     Cable modems are also a new technology. Obviously, you must have cable in your area to get cable internet access. Not all cable providers have internet capabilities. Most cable connections prohibit running servers.

     Some areas are using wireless technologies. Rural areas are an ideal target for these. These are still pretty new. Watch for these, they might get real interesting in the next few years as the technologies shake out.

     Costs vary quite a bit for each of the high speed options. Some options, like DSL you often pay an ISP and the phone company for your lines.

Domain Name Service (DNS)

     Domain Name Service (DNS) really is the backbone of the internet. Never heard of it? Good, that means yours is working great!

     The internet is based on a system of IP addresses. These take the form ###.###.###.### where each ### is a decimal number between 0-255. An IP system is limits the network to 4 billion addresses. As humans, we tend to remember names better than numbers. So the internet uses names like www.amazon.com. The DNS server makes the translation to IP's for us.

     DNS is actually an hierarchical distributed database. Now there is a buzz word you can amaze your friends with. Now, let's define it so you can really astound them!

     In a nutshell, the term hierarchical in this case means that one controls a few which control the rest. One what?

     Let's say you have a company network. Your Network Guy has probably got a map of some kind to define the network. On the internet, each small network is defined (mapped) by the local DNS server. Each machine on the local network is assigned an IP address.

     Now, when someone outside calls a resource on this small network, this DNS server is called. This DNS server is known by a ROOT DNS server. Each ROOT DNS server controls a top-level domain such as .COM or .ORG etc.

     A central database knows where every ROOT DNS server is and is also the registration clearing house. Just recently, control of this huge database has been distributed to hundreds of companies.

     OK, why do we care about all this? Every domain must be referenced by at least two DNS servers. If one goes down, the other must take over. If they both go down, you are lost. Not only can nobody find you, but if you use this ISP for access, you can't find anybody else either.

Web Servers

So you say "I want to make my own web page." You need a home for your files. The web server stores the files and distributes them to everyone who comes along, that wants to see it.

An internet web page hosting service should not only run your HTML files, but should also be capable of CGI and Perl scripts.
