Web Hosting - DNS, How The Internet Keeps Track of Names
The way computers communicate is, in a way, very similar to something very familiar: the postal system that delivers letters and packages. Here's how...
The Internet is just what the name suggests, a large inter-connected set of networks. But those networks are pointless without the one part that forms what is called their 'end-nodes', otherwise known as computers. Those computers often need to share information because the people who use them want to share information.
But, in a system where there are millions of separate computers, how can you enable them all to communicate? One very important feature of that solution is performed by something called DNS, the Domain Name System.
Every part of a network that is going to send or receive information is assigned an IP address. That's a numeric identifier that uniquely specifies a particular 'node', such as a computer, a router that directs traffic or other component. They look like this: 209.131.36.158
But those numbers are more difficult for people to remember and work with. They also aren't very attractive from a marketing perspective. So, a naming system was layered on top of some of them, mostly the computers involved, though routers have names, too.
But once you have a system that associates a unique IP address to a given name, you need some way of keeping track of all of them. That's carried out by several different pieces of the system: Name Registrars, DNS Servers and other components.
The Name Registrars, overseen by IANA (Internet Assigned Numbers Authority) and other international bodies, provide and keep track of domain names. When you register with GoDaddy or any of a hundred other intermediate companies, ultimately that information makes its way into a number of specialized databases stored inside DNS Servers.
A DNS Server is the hardware and/or software that tracks and forwards the IP Address/Domain Name pair from one place to the next. In many cases, there are a number of them between your browser and the remote computer you want to share information with.
Suppose you request information from, say, Yahoo's site by clicking on a link on their site. DNS resolves (translates) the name of WHO IS making the request and OF WHOM, to addresses, then passes the request through the network to the requested IP address. The requested data is then passed back through the mesh of network components to your computer and displayed in your browser.
Whether the communication is between a desktop computer and a server somewhere, or between one server and another, the process is essentially the same. DNS servers translate names into IP addresses and the requests for data are forwarded on.
In some cases those DNS servers are part of a specialized network computer whose sole job is to do the translation and forwarding. In other cases the DNS software may reside on a server that also houses a database of general data, or stores email, or performs other functions.
But however complicated the chain or the parts, the basic process is simple. Translate the name to an address, just as the postal system does. Whether international or local, your name is associated with an address, and the deliveries are made to the address, then forwarded to a particular name.
Is Christian Publishing the Easy Road to the World of Writing Success? (Christian publishing) Any community with a special interest will pay for products that cater to that special interest. If that community is of significant size, you can bet that there will be products galore geared to them. There is money to be made where there is a need for a product. The Christian community is one such group that has a desire for a very specific product. They are interested in products that explain their faith and expand their knowledge of what is less understood within that faith. They also seek encouragement in what is already agreed upon. Because of all of these needs, there is certainly a market to be entered into within the Christian publishing network. The question is, since the group is exclusive, does that mean that there are too few writers for the consumers? Is it easier to get published when you’re not competing with the best of the secular authors? Those are difficult questions to answer with any certainty, but there are some topics to explore within that subject. Degree of Expertise In one genre of Christian publishing one qualification is essential. To write with expertise on subjects of faith, it is necessary to have the correct education. A seminary degree at the very least is required for convincing publications. The publishers do not accept authoritative writing from those without the proper education. When it comes to education, separate Christian denominations will expect degrees endorsed from those specific denominations. You may have expected that a Christian would need to write for the Christian community, but the requirements can be much more stringent. Just as a pastor or preacher must have the proper education to teach a congregation, a writer on subjects of theology or other topics from the Bible must also have the credentials to back up his claims. While it is not possible for every writer to obtain the correct degree for authoritative writing, there are other kinds of writing that will easier to achieve within Christian publishing. Experiential Knowledge A huge portion of Christian publishing is made up of personal stories. A Christian has unique experiences related to his faith. People who seek encouragement will buy books that relate to their own circumstances. A typical human problem is grief. If a Christian can effectively write about their grief from a perspective of faith then those writings will be helpful to other struggling Christians. Other important subjects include doubt, blessings and prayer. A lay Christian can back up their experiences and observations with scripture and therefore be much more relevant in their writing to the Christian community. If the writer’s material is not sufficient to fill a book, there are other outlets within Christian publishing for those who are able to inform and encourage fellow Christians. Magazines and church bulletins often publish poetry and short stories for the building up of believers. The Bottom Line Christian publishing may not be necessarily easier to do than secular publishing. If your heart is in the ministry to other Christians however, it may be the best field for you to attempt writing for. Christian publishing is not a ‘first step’ to enter into the publishing world. Most publishers are only looking for sincere and relevant publications. They will avoid writings done only for the money and will favor those with the honest goal of furthering the message of the Christian faith. Specific communities are looking for products geared to their lifestyles, but the best candidates for creating those products are those who have talent invested in that community. Entering into the Christian publishing world will be a similar task to entering into the scientific publishing world. It will take dedication and work. The writer will come out with a deeper understanding and faith of his own. Web Hosting - Do It Yourself Administration, Things to Consider The choice of whether or not to try to administer your own web site brings with it a host, pun intended, of issues. For most web site owners, the primary focus is naturally on creating, maintaining and enhancing the site. That often is just part of managing an entire business, for which the web site is just the means to an end. That implies there will be little interest in or time left over for technical administration like database maintenance (tuning, space management, security, bug fixes), establishing and maintaining backups to ensure they're successful and usable, email administration, disk space management, applying operating system fixes for bugs and security, and other tasks. But cost is always a factor in any business. Paying for technical help can burden the budget of a new and struggling business. Consulting fees can range from a few dollars an hour to over $100. On the lower end, the poor skill level and quality of work will make it not worth even that small amount. On the higher end, you can quickly rack up expenses that will bust your business. Permanent employees are usually somewhere in the middle of that range when you add up salary, employment taxes and more. Often, server and/or web site administration can be paid for as part of the web hosting package. That cost is usually lower than independent contracting help, but those staff are usually tasked with maintaining dozens if not hundreds of servers and sites. They can, therefore, give very little individual attention to yours. Often, novice web site owners are intimidated by some of the technical requirements for server or site administration. But, as with anything, a little familiarity can show that the knowledge required is more modest than one might expect. Administration in many cases involves fairly elementary, and frequently repetitive, tasks. These can be learned easily. Using a test site or a free hosting service is a good way to practice and learn without risk or cost, other than time invested. Once that initial hurdle is jumped over, administration can be done quickly and some even find it interesting. It allows the site owner to exercise additional control over the total product, and there's satisfaction in being able to say 'I did that' even if you prefer not to do it forever. That real-life learning experience also allows the site owner to better judge any consultants or staff that are hired. It's much easier to judge if someone is providing you with an accurate assessment of a problem if you've solved it yourself. Any time-estimate they provide to fix it can also be better calculated if you've had to do it yourself. Every web site relies on a variety of factors, usually unseen, in order to continue to function properly. But the fact is that they misbehave from time to time. Deciding whether to tackle those problems yourself depends on your available time and skill set, and what it will require to get things back on track. In other words, it's a standard cost-benefit analysis that everyone has to undertake every day in life. |
