Web Programming

Web hosting can be defined as renting space on a web server in its simplest form. Note that a site is a collection of files linked together by HTML code to display text and images on a computer. However, the website is not complete until and unless it appears on the network. To make it visible for the world to be held on a computer somewhere that has Internet access. This is only possible from a computer requires some “special device known as a web server. A Web server can be defined as a computer configured with special software that allows you to receive requests from the website of the files you have stored on it and send out those files on the Internet for the computer screen may require .
Web server, and making visible the place has several other works, and provides the ability to create email addresses based on a domain name and also helps in sending and receiving emails with them. There are several types of software installed on your web server that allows your website to run programs, create and manage databases, video screens, etc. It should be noted that almost any computer can function as a Web server, but the software is about what makes a server.
When you go to buy a web hosting, pay the monthly fee includes the cost of maintenance and updating of hardware and server software, the cost of maintaining online 24 hours a day, seven days a week at a center secure data with an Internet connection fast and powerful, and cost of certification of service category. It is amazing to know that you can transform your home computer or office on a web server, if you really want, but not just economic. Therefore, it is better to outsource. There are several types of web hosting available which are described below:
Types of web hosting:
Shared Hosting – Through a shared server can save a lot. If you speak then of nuisance and spam blacklist different search engines are the key issues. These problems arise due to the reason that many sites are assigned to a specific IP address. You must request a separate IP address for your website (additional monthly fee) to protect against these problems.
Dedicated Servers, Dedicated Hosting are the best places of great size, very busy, which require large amounts of server resources to operate. One drawback is that shared hosting server resources are shared among all hosting sites and respond to page requests. If you are a dedicated environment can better manage server resources. The disadvantage is that dedicated servers will run between $ 50 a month or more. Shared accommodation can be bought for as little as $ 5 per month. Most small and medium-sized enterprises have neither the size of the bandwidth requirements of website or to make expenditures dedicated servers.
Server Co-Location – If you want to have total control over all aspects of your web server, you may choose to purchase one to keep for yourself if you have sufficient knowledge. Still there are chances that one is not having sufficient resources to maintain its own server completely safe from power outages, roof leaks, thieves, unwary employees and other problems and it is not possible for him / her to follow Internet on a fast broadband connection through out. So you need a data center to provide these services for him / her.
Co-location is the center that provides services such as physical security for rent, electric power and a fast and reliable connection to the Internet to a server that has. However, the data center is not responsible for any of the hardware and software maintenance on a server co-located, but his car. Therefore, it is a cheaper alternative to dedicated hosting if anyone is in possession of the necessary skills and time to run a personal Web server.
There are several web hosts offering UNIX hosting and Windows hosting.
UNIX Hosting
There are several web servers across the world, especially that run on UNIX. UNIX is an operating system originally developed for servers and networks. Until now many versions of UNIX were written by programmers around the world under the open source protocol, which means that the code for the operating system is openly available to allow developers to customize and make improvements where necessary. The two most popular Linux and BSD UNIX, which is available in different varieties such as Red Hat Linux, Debian, SuSE and FreeBSD. The best part of most UNIX versions listed above are available for free, which makes UNIX hosting cheaper for a web host than other operating systems. Other strengths of UNIX UNIX hosting platforms are generally considered stable, secure, powerful and fast. This is the reason why most web application programming can be performed by software that is available for the UNIX platform.
Windows Hosting
Another very popular operating system developed by the Microsoft Windows operating system, Windows Server 2003. Like any good thing is that the price and can be obtained by purchasing a license, which in turn increases the cost of operating the network host and usually results in higher prices for housing. This is considered a disadvantage compared to UNIX. Plus points include Windows is especially easy to use, but is generally considered less powerful and reliable UNIX operating in a network environment. There are several scripting languages such as ASP, ASP. NET and Cold Fusion, which only runs on Windows Server and Microsoft SQL Server and Microsoft programs, Access database. So above are some of the scripts most popular web programming for some applications and when you think the use in building your site, he or she definitely needs first to find a Windows host.

There are different levels of package, so you pay more for more space, and vice versa divide in particular that the space above. If a website expands its space then you must purchase additional space web hosting.

There are several web hosts offer some sort of traffic statistics software with their hosting packages.
CGI scripts – There are several web hosts offering a variety of free CGI scripts with their packages. CGI scripts are things like counters, guestbooks, form mail programs, message boards and other programs that allow a website to perform the desired functions.
