What To Look For In Web Hosting Selection PDF Print E-mail
So, you decided to host your domain or website on the World Wide Web. Good, do you know how to decide on the best web-hosting package? Let me help you with a few guiding points to make a good and informed decision. There are a great number of factors in choosing and I am going to describe each very briefly:

1.Reliability of the server and Uptime
2.Traffic Transfer or Bandwidth
3.Disk or storage space
4.Technical or service support
5.Add-ons capacity

Reliability of the servers and Uptime: The servers of the web host should be reliable and should have a continuous uptime of a minimum 99.5%. The server reliability translates into the availability of your website on the net. If someone tries to access your site and they get ‘server not found’ message too many times, they will shift their business elsewhere. A good web host will guarantee 99.8% uptime round the clock 7 days a week.

Traffic Transfer or Bandwidth: Traffic transfer or bandwidth refers to the capacity of the web host to accommodate simultaneous access to your website. This is measured by the bytes number (amount) transferred by your site when web surfers access your site on the web. All web hosts will charge for this service and there is no such thing as ‘limitless bandwidth’. It is good if you can find out the details before hand so as to avoid bad surprises with high bills for data transfer. A simple website will be comfortable with about 50 GB to 100GB.

Disk or storage space: As important as the traffic transfer size, is the disk or storage space. Similarly, you should look out for a minimum 200 MB. Many web hosts will and can offer you larger disk / storage spaces, which is absolutely fine. However, keep in mind that even if you are a totally professional site you may not need more than 5000 MB. So, a realistic move is to aim at 200– 1000 MB as disk/storage space.

Technical support: Look for history of the web host and find out their approach and time of rectification of different problems that can crop up with the server and sites. All web hosting entities will assure you of round-the-clock service seven-days-a-week. However, very few really function this way. It is very important to have a good service support so as to have an interrupted access to your site. Be careful of free services and false assurances in this field as it can destroy your business with lack of proper support.

Add-ons capacity: You should be able, unless you prefer otherwise, to add, update, and delete things in your website yourself. The most normal of these things would be managing your email, passwords and creating different accounts. There are more advanced features with the control panel of the host, which could allow you to add or delete extra items on your website directly. You should find out the amount of liberty your host can extend to you.

In case you are planning to run a business complete with financial transactions, order forms, you will need additional services like secure server for credit card encrypting and the like.

Other plus points are email auto-responders, mail forward, re-routing, and multiple accesses. This would ensure that your negotiations cover all bases.

All About The DNS Domain Name System
We all know that in the world of domain names today, the presence of the DNS domain name system is very much significant. It is interesting to know that the acronym DNS actually stands for Domain Name System/Service/Server. However, I will be using the term DNS domain name system here to provide you with a clear knowledge about the meaning of this particular thing.

The DNS domain name system is actually a powerful tool that contributes a great part in the domain name process. It is often described as an internet service that translates or transforms the domain names into an IP or Internet Protocol address.

Aside from knowing such basic function of the DNS domain name system, it is also interesting to learn that a basic possession of the DNS domain name system is caching. This property takes place in situations when a server welcomes information about a mapping, it caches that information. Therefore, with such function, a later question for similar mapping can use the cached output, and will not result to additional questions to other servers. And generally, the DNS domain name system applies the caching to optimize the cost of the search. But how does the DNS domain name system caching works?

In terms of caching, it is very nice to know that every server has a cache for currently applied names along with records of where the mapping data for a particular name was taken. So when a particular client is asking the server to determine a certain domain name, the DNS domain name system then does check if it has the power for a domain name, and if it does, the system doesn’t need to cache the information. However, if it has no authority for a domain name, the DNS domain name system then checks its cache whether the domain name has been resolved currently, and if yes, the DNS domain name system reports the caching data to its clients.

There are some instances that the DNS domain name system cache can be examined when the system cached the data once, but didn’t adjust it. Due to the reason that the information about a certain domain name can be changed, the server may have inaccurate data in its caching table. There is a certain value known as the Time to Live or known as TTL which is applied when to age the information. So whenever an authority responds to a request for a domain name, it then involves a Time to Live value in the answer which indicates how long it assures the binding to linger.
