Data Center

A service that is used to provide a huge amount of electrical equipment that can be either computers or other communication equipment is known as a data center. It is an association that is solely maintained for the purpose of managing or organizing data that is essentially required to be used for daily operations. For example, the data center of a bank would store all detailed information of its customers. All companies have a data center of their own large scale companies may even multiple data centers. For the large cities, the data centers are provided with their own individual data location to prevent theft of data and to maintain security of the important data contained.
The organizations providing the data center service handle the data contained by them with utmost security as it is the lifeline of the company. Therefore the data center organization maintains high level or integrity and provides optimum functionality of the computer environment that it hosts for. This is usually shown by the general layout of the data center.
The data center can cover the area of a room to an entire building depending upon its size. Most of the data are stored in for of racks with corridors provided between them for easy access. The servers that are available vary from 1u servers to huge silos that occupy various tiles stacked upon the floor. Some of the mainframe computers and storage devices are often as big as the racks and are placed next to them.The communications are mostly based on the ip protocol service in most data centers. They are equipped with routers and switches which comprise of the critical components that act as transporters of traffic to the outside world from the servers. Using two or more upstream service providers provide redundancy to the available internet connection.Some of the datacenters run the basic internet and intranet services like email servers, proxy servers, DNS servers etc.
As mentioned earlier, the data that is available in the centers are treated with utmost security. Many network security elements are employed to keep the data safe. Such as firewalls, VpN gateway, Intrusion detection systems to detect malicious activities etc. are incorporated. Common monitoring systems and other such applications are also available. For added security for emergency situations such as failure of communication inside the data center, offsite monitoring systems are also provided.

A Domain Name System or DNS can be considered to be the “address” of a particular source of information (or website) available on the Internet. The most important function of DNS is to provide an interface through which plaintext words which can be understood by human beings i.e. the web address of a particular site is translated into a set of numbers readable by the computer.
DNS is also used to store a lot of information such as lists of mail servers which will accept electronic mails, for a particular domain. DNS is a highly essential component for internet usage as it provides universal redirection service which is based on keyboard operations.
The DNS space consists of a tree of domain names. One or more resource records are a part of a node or a leaf which holds information associated with the domain name. This DNS domain name tree is subdivided into a number of zones. A zone is nothing other than a set of nodes connected together and served by a common DNS nameserver. This process is however authoritative.A resolver is used to look up the information associated with all the nodes. A resolver communicates with a nameserver by sending it various DNS requests, and then analyzing the DNS responses it receives from the nameserver. Resolving is an iterative process which involves looping through multiple DNS nameservers in order to obtain the required information.
DNS is a collection of multiple DNS servers. Each domain and subdomain will have one or more authoritative dedicated DNS servers which possess all information about that domain. The hierarchy of the domains and subdomains is reflected in the hierarchy of the Domain Name System Servers. At the head of the hierarchy tree is the root nameserver. A root nameserver is the server which is queried by the resolver.
The facility of local caching is also available in the DNS resolution process. Caching is the recording of the results of a DNS query for a certain amount of time when a successful answer is obtained. The resolver takes a certain amount of time to cache each DNS response. This time is known as the Time To Live (TTL)an it is the duration a DNS response will remain valid. Such a TTL may range from a few seconds to several days and in very rare cases even weeks.
The DNS is also used for other applications such as :-Hostnames and IP addresses do not always match on a one-to-one basis. Several hostnames may correspond to a single IP address and may be combined with virtual hosting, this allows a single machine to serve many web sites. In an alternative basis a single hostname may correspond to many IP addresses.

It is quite commonplace to observe that in many kinds of markets a particular brand tries to secure the majority of consumers. Such a habit is termed as monopoly. When it comes to the operating systems for personal computers Microsoft is a corporation that is accused of this practice. With its hugely popular Windows family of operating systems Microsoft enjoys a large part of domestic and corporate customer base. However, in recent times certain small contenders have raised their head to give it some serious competition. In the sphere of web servers, the most prevalent operating system is Microsoft Windows 2000, which is touted by the company as a true server class OS. It holds a large share of the server operating systems. But in recent times Linux has risen to a challenging position and it is being considered by many as the proverbial Goliath to counter Microsoft’s monopoly.

Many people believe that Microsoft is the supreme as far as computer system is concerned. However there are serious challenges to the issue now with other hosting services as Linux stepping in. It cannot be denied that even today most people prefer Microsoft to any thing else. However as per the current trend the hosting services as Linux too are gaining immense popularity. What makes this hosting service popular? How does these two systems compare? In the article below we discuss the pros and cons.
Using a Windows OS does not require you to opt for Windows web hosting. Linux is a suitable contender. If you have the technical know how of using your web publishing application and FTP, you can resort to the web host you like. It actually depends on the purpose you want your site to serve. As a matter of fact interactive websites use languages like PHP, Perl or ASP.
For web hosting purposes Linux is said to have more benefits than Windows. It is relatively more steady, secured and efficient and meets the requirements of challenging environments of Web servers. Only if you use Microsoft oriented languages you should resort to Windows. For mainly informative sites Linux is the best choice. But when it comes to having interactive chat sites or databases in your site Windows 2000 is a better choice.
A web address developed for a Linux based server can easily be moved to a Windows based server. The opposite is not so easy. Linux traditionally gives a stable and rock solid foundation to your site. A web site based on Linux hosting usually has superior up-time than its windows counterpart. The Linux, as everyone knows, comes for free or occasionally at a meager distribution rate. This has led to its popularity among cash-stripped users. It bundles many applications with the OS that comes in handy in work and are as reliable as the OS. A Linux based web hosting is more suitable for upgrading and modifying an existing web site since it offers more scalability than Windows.

Bandwidth

Now for all you people who are new at computers you may wonder what a web hosting band width is? How is it measured may be another question in your mind! Well take heart. For we are here to tell you what web hosting band width is all about.
When one starts searching for the most suitable web hosting service the issue that bothers him is the bandwidth of the service. It is indeed a deciding factor to your websites performance as well as success. In plain words, Web hosting bandwidth is the quantity of data transfer that the web site faces. Bandwidth in measured in units called Bits. If you visualize bandwidth as a highway, the term traffic can be visualized as cars on that road.
Bandwidth can mean the data trafficking capacity of the network. Alternatively it can also signify the data limit your web hosting service has allotted you for a time period. Different web hosting services have different policies for their consumers. The reason the hosting company monitors the bandwidth consumption of a site is to restrict it from exceeding the limit. If a web site overuses the bandwidth it will cause a server downfall. A slow loading web site in the web browser is a surefire sign of inadequate bandwidth.
If you are thinking how much of bandwidth is adequate for you, the answer is that it depends on your site’s content and the purpose. For example, a text heavy site will be smaller in size compared to a site rich in audio visual and interactive contents. A hosting bandwidth that is enough for the former can prove to be a bottleneck for the latter. So the larger the download or upload files are, the bigger amount of bandwidth is required. Also remember, even if a visitor does not upload and download any file, the mere loading of the page in his browser window consumes some bandwidth. As a matter of fact most web hosting services measure bandwidth in units of GB. You can make an average estimate by calculating factors like the average number of users per month, average page views, and average page size etc.

Some people say that advertising is everything! Regardless if you have a product, a service, a hobby website or just want to share pictures of your wedding, you have to advertise somehow to get the traffic to your site or blog.
But not all traffic is equal. There are services that can help you drive tons and tons of traffic to your site and it won't do you any good at all because it's not targeted traffic.
Webmasters and marketers that want traffic on their own site. So they most likely won't spend any more time on your page than is required by the little timer these services use and then they are gone again. Even if your site is about these traffic services (this is about the only time you will see very much benefit from using such a tool) you will still have to spend a ton of time just surfing and clicking around to get a real benefit from these programs. Once marketers realized this they switched gears. They started promoting all the different programs to a lot of other marketers to get them in their downlines, so they could get some traffic as a bonus. This became their new focus. The problem is that everyone else did exactly the same thing, so not a lot of people were surfing the internet anymore.here are some tips on how you can generate exactly the traffic you need and bring the visitors you want to your website without having to chase after them

Content
What is your website about? Do you just have a page with a lot of links and not much else? If this is the case, think about adding some content to your website that will be of value to any potential visitors. You could write articles or find articles at one of the many directories that you can reprint on your site. Talk about your experiences in your subject matter. You don't have to put up some kind of resume (although that can work too), but rather try writing about what you are doing, as it relates to your topic of choice. Let's look at the model airplanes again briefly, you could talk or write about the latest plane type you built, how the last time flying your plane went, what challenges you run into or perhaps even post some pictures of your plane or of you flying it.

Forums and bulletin boards.
You could add a forum or bulletin board to your website where your visitors can interact with each other. There are a lot of free services available out there that you can use to either remotely host a forum for you, or even software you can install on your website's server. To find some of these, just head over to your favorite search engine and you will definitely find plenty to choose from. And while you are visiting the search engine, why not run a search for any bulletin boards and forums that are already out there for your chosen topic? You could visit those and interact with the visitors there and since many allow you to post a signature or a profile, you could add a little line about your own site with a link (just check the rules of the forum first so you don't violate any of them).

Start a blog.
Blogs are very popular and search engines love them because they provide constantly new and fresh content. Your blog would be a great place to talk about what you are up to that day. So if you spent some time today buying new parts for your plane you could write about where you found them, how much they cost you, why you chose those parts, anything really goes. The really great part about this is that you can point links from your blog back to your website, so when the search engine stops by to grab and index your latest content, it will also stop by your website and you will start seeing very targeted traffic heading your way

Write articles.
Writing articles isn't hard and can be a great source of fresh, new traffic to your website. There are a lot of ezines on any topic out there and there are also a lot of directories where you can share your article. Basically, what you do is write an article and then add a small resource box that links back to your website (just like a signature) and then let other ezine publishers know that you are allowing them to print your article in their ezine. And many publishers go to the article directories to find new content for their newsletter and even their websites. And since there are websites and ezine newsletters on any imaginable topic out there, you can't lose. Write an article every couple of days and post it in the directories (even one a week or every two weeks will start getting you traffic). Very soon you will find new traffic coming from search engines, newsletters and websites. Best of all, these five simple tips will bring targeted traffic, meaning the visitors are coming to you because they are interested in what you wrote. So there you have it. Whether you have a simple and basic Work at Home Business or a significant Internet Marketing enterprise you can benefit from these five easy and simple ways to advertise and drive traffic to your website at absolutely no cost.

When webmasters have created their final master piece, their next step is to promote, promote and promote. This is a vital step in survival of your website and will increase your sales and visitors.Many webmasters, especially beginners, gets so excited and want to take major steps so that they can get hundreds of visitors next day. Sometimes they try to adopt many illegal ways to promote their website. This causes their website to be banned from major search engines and as well as it is disliked by many people. Conclusively this decreases your website reputation drastically.Its cause is sometime a wrong advice or some people do these steps purposely to increase traffic without knowing its side effects. We will discuss here these website promotion mistakes and we would advice you to never use these techniques if possible.

Never Submit Your Website When Under construction: It is always better to submit your website when it is fully functional. This leaves a real bad impression on directories or search engine, wherever you submit to. If your visitors see a under construction sign, many of them are not going to come again, especially if this sign stays for longer.

Do Not SPAM: Spamming can be of different types. I would concentrate on email spamming now. Never force anyone, by sending them emails, to view your website or product, especially if they have not subscribed for that. There are many offers available on net that you can get thousands of emails list and use it for your advertising. Never trust them whatever they say. You are not going to gain anything; however, you could make more enemies and get your website banned sometimes.

Redirectors: Many websites use redirectors or set their fresh rates too high. It really has a bad effect on search engine ranking. Try to avoid them as much as possible.
Avoid Wrong Methods Of Web page Optimization:Many people still use those old methods to hide text by changing its color with back ground color so making it invisible to see. Do not also try to hide text with layers. This was good enough in 1995 when search engines were in their developing stages. Now they have got quite intelligent to overcome such techniques and give penalty to websites using such technique.

Don’t Create Doorway Pages: Many search engine optimizers did reverse engineering and get lot of knowledge about search engine algorithms. They used this knowledge to create doorway pages or welcome pages or jump pages, which were used to get first 10 positions in search engines. These pages were very well optimized for search engines and ranked very well.That is good if your website is very much dynamic and its pages are not well ranked by search engines. But how could spammers can stay away? Then every spammer used these techniques excessively and conclusively it became difficult for people to get relevant content. Search engines then realized this trend of increasing such vast amount of doorway pages and they penalize those websites now which use these techniques. So I would recommend to never using this method to promote your website.

Don’t Involve in Link Making Schemes: I would recommend you to increase your page rank but not by using unreliable link producing schemes. Search engines have become very choosy about which type of links a website is having.So it is better to never involve in links farms, auto link exchange programs, site networks. Search engines penalize hardly those websites who try to artificially increase their incoming links or suddenly gain so many links in very small amount of time.It is better to get links by legal ways. Get them from quality websites and try your best to inbound links only.

Keyword Frequency: It is always advised that you should not stuff your web page only with key words, instead of using your primary keyword hundreds of times, pay your attention to contents. If you are really so concerned about your keywords then it is better to use different keywords at different places in your website.

Don’t Spend Your Time On Scrap: Sometimes we may have seen websites showing guaranteed no. 1 position in search engines or submit your website to 1500 and plus search engines. They are lire mostly. Because there are only about 10 major search engines which receive about 95% of the internet traffic. All other search engines are smaller ones and get their primary results from major search engines.It is a real wastage of time and money if you are going to use those schemes. Sometimes they also optimize your website in such way that it can even get banned, so be careful.

Don’t Buy Untargeted Traffic: Many websites claim that they will send 10,000 visitors or so. What do you think, will that be targeted traffic and will that traffic change into your potential customers? Think carefully and then decide before choosing any such type of offer.

In this article I will tell you about my top 5 free ways of increasing website traffic.All these methods are completely free and if you spend some time on them you will find that they work consistently.

(1)Writing Articles
Writing an article on a subject related to your website and getting that article published has two major benefits: - People who are interested in your article will read it and often click on the URL in your resource box find out more. This gets you another free targeted visitor. Targeted, because that reader wants to find out more on the subject of your article, which is hopefully related to the subject of your website. - Every publisher of your article must also publish your "resource box". Adding a resource box with your URL to all of your articles will increase the number of links leading back to your website, which in turn helps to increase your search engine position For a list of directories to submit your article to, see Article Submission Directories

(2)Forum
There are many discussion forums on the internet, on every topic you could possibly imagine. Most discussion boards allow posters to attach a "Signature" with their post containing additional information about themselves, such as their name, URL and sometimes even an advertisement. By visiting a few forums regularly and participating in the discussions, asking and answering questions, you can build up trust with other forum members, whilst at the same time getting free exposure for your website. Just try to make a useful contribution to the forum - be sure to read the forum rules and don't spam!

(3)Reciprocal Linking
Reciprocal linking has two main benefits for you. Firstly, the more links that you exchange, the more chance there is that someone will follow a link from another site and land on your website. Secondly, your website will be perceived more importantly by search engines. The more links you have from other sites, the greater your chance of getter ranked more highly by all the search engines. Here are some Dos and Don'ts to help you get more out of your link exchanges. - Do link with sites that will be of interest to your visitors. - Don't link with pages that have unorganised link directories with hundreds of links on each page. This won't benefit you with increased traffic or search engine rankings. - Do link with sites that have a clearly labelled "Link Directory" from their main page. You aren't likely to get much traffic from a hidden or hard to find link directory. - Don't use link farms or FFA pages. You are unlikely to get extra traffic using these methods and the search engines may penalise you. - Do use link directories to help you find link partners. You can find some Link Exchange Resources here- Do stay organised. Use link exchange software, or a spreadsheet to keep track of the link exchanges you have requested and the contact details of the webmasters.

(4) Email Signatures
This is a very simple, but often forgotten way of increasing your website visitors. Most of us are sending lots of emails a day, but many of us just sign them with just our name, or perhaps nothing at all. Instead, why not end your emails with a short signature containing your name, a bit about your website along with the URL? Keep the signature short (4 lines), to the point and avoid hype or SHOUTING. You may be surprised at the extra visitors you receive through doing this. It's amazing how curiosity will lead the recipients of your email to click on your link!

(5)Using Traffic Exchanges
Finally, this is one easy way to guarantee instant hits to your website. You can build up credits for free by surfing or building up a downline to surf for you. The downside of this method is that the visitors you receive from traffic exchanges are not as targeted as the visitors that you will receive via the other methods that I have described. The reason for this is that people surf traffic exchanges for one reason - to earn as many credits as possible in as short a space of time as possible! This gives you a challenge - how do you attract the attention of someone who is looking at your web page for 20 seconds or less? Here are two tips - - Know your market - spend some time surfing on the exchange that you are advertising on and pay attention to the types of web pages being advertised. Make sure that the pages you advertise are going to interest your target market. - Use a short, simple attention grabbing page that can be read in a few seconds - there is no point advertising a huge page of text that takes 5 minutes to read. The chances are, your visitor will get bored and click on the "next" button without giving your page a fair chance. Regularly invest some time in each of these 5 traffic generating methods and you will see your web statistics moving in the upwards direction before you know it.

Many web designers do not pay attention in coding structure, the result is no one can find those websites in search engines!. In many cases search engine spiders cannot crawl 100% of those sites, this is because of huge size, html code error, navigation problem due to using scripts. By following these ten tips while designing and developing your website, you can improve your web presence.
1) Table structure: Nested tables can cause the huge page size and it could be problem with download times. Use separate tables wherever possible. Rather than using tables, use CSS to format your page layouts.
2) Page size: small web pages load faster. Make your page size to below 50K, so that search engine spiders can able to crawl your entire website without having any time delay.
3) Frames: Do not use Frames. Some search engines not even supported frames and it could be some display/alignment problem with some browsers. It could also affect while bookmarking a page. Remember, whatever you are trying to accomplish by using frames can usually be done with CSS.
4) Alt tags: Minimize the use of graphics and Flash. If your site having graphics try to explain those by adding ALT text. Since search engine spiders cannot read text within images, you should provide alternative text, so that spiders can understands what they mean.
5) Navigation: Each pages on your website should be easily connected. Use of JavaScript links and image maps may affect spidering your entire site or you should use text links at the bottom of your page to help search engine spiders to navigate each pages. Try to check your web pages in a text only browser and ensure you can easily navigate all the pages from page to page.
6) Title and Meta tags: Add title and Meta tags to each pages in your site and all title tags and Meta tags should be unique.
7) Sitemap: Provide a sitemap that linked from your homepage. It must be essential if your site having dynamic pages, that contains special characters such as ?,%,&,# etc. As these pages are generated automatically, search engines spiders cannot follow these links.
8) HTML codes: Internet explorer can display your page even if any minor errors in the html code, but it could be a major problem with search engine spiders. I recommend validating your html codes through some online tools that available in the net. By getting W3C standards can give your web pages greater visibility in web searches.
9) Cascading Style Sheets: CSS enables you to independently control the structure of your web page. By using CSS, you will get its benefits like smaller file sizes, browser compatibility and search engine friendly.
10) External CSS/JavaScript files: Call all your JavaScript and CSS from external file, so that spiders can easily access your data without causing any error.
