In computing, an internet space defines a range of discrete addresses, each of which may correspond to a network host.
Internet spaces are created by combining enough uniquely identified qualifiers to make an address unambiguous. Components of an internet space may be the same but unless all are identical, the locations will be different.
An internet space usually provides (or allows) a partitioning to several regions according to mathematical structure it has. Some nested domains hierarchy appears in the case of directed ordered tree as for the Domain Name System or a directory structure. In the Internet the Internet Assigned Numbers Authority (IANA) allocates ranges of IP addresses to various registries in order to enable them to each manage their parts of the global Internet address space.
The user-friendly interface of the Internet is based on a multi-layer global network system connecting hundreds of millions of computers worldwide. This system is comprised of multiple local and global networks serving private, public, business, academic and government purposes.
The Uniform resource locator, popular as URL, is the global web address of documents, including web pages or image files, and programs such as Java applets. It is aimed at identifying the location of a document or a program available on the web and specifies the mechanism for accessing it through a web browser.
Internet addresses can be linked to the objects, and the final scenes can be published on the Web. Internet space is used to upload your website on the internet or in simple words we can say that if a person or company wants his website to be accessed on the internet then he or she has to buy internet space on the internet this is called IP address and is unique for all.
Uses of addresses include, but are not limited to the following:
* Various kinds of network host addresses in computer networks;
* Uniform resource locators in the Internet.
Another common feature of internet spaces is mapping and translation, often forming numerous layers. This usually means that some higher-level address must be translated to lower-level ones in some way.
The Domain Name System maps its names to (and from) network-specific addresses (usually IP addresses), which in turn may be mapped to link layer network addresses via Address Resolution Protocol. Also, network address translation may occur on the edge of different IP spaces, such as a local area network and the Internet

It sounds like maybe the PDO extension isn’t installed in your PHP.

Run phpinfo on your server to see if you have PDO enable, if so add this in your php.ini if you are on shared hosting. This solve my problem on my side !

• create a blank file in your drupal or server root named ‘phpinfo.php’
• add the following code into the file

<?php
phpinfo();
?>

• go to the file via a browser, e.g. yoursite.com/phpinfo.php
• look (ctrl/cmd + F) for the ‘Configuration File (php.ini) Path’, you’ll find the location of your php.ini file there

If you are unable to acces this through FTP/cPanel/…, create a file named php.ini in your drupal root folder and add the following lines of code:

extension=”pdo.so”
extension=”pdo_mysql.so”
upload_max_filesize = 10M
post_max_size =64M
memory_limit = 64M
upload_tmp_dir = 64M
max_execution_time = 128

Note : that you may want to tweak these values depending on your needs.

A shared web hosting service or virtual hosting service or derive host refers to a web hosting service where many websites reside on one web server connected to the Internet. Each site has its own section/place on the server, to keep it separate from other sites. This is generally the most economical option for hosting, as many people share the overall cost of server maintenance.
In general shared hosting will be inappropriate for users who require extensive software development outside what the hosting provider supports. Almost all applications intended to be on a standard web server work fine with a shared web hosting service. But on the other hand, shared hosting is cheaper than other types of hosting such as dedicated server hosting. Shared hosting usually has usage limits and hosting providers should have extensive reliability features in place.
Shared hosting typically uses a web-based control panel system, such as cPanel, Plesk, H-Sphere or one of many other control panel products. Most of the large hosting companies use their own custom developed control panel.
In shared hosting, the provider is generally responsible for managing servers, installing server software, security updates, technical support, and other aspects of the service. Most servers are based on the Linux operating system and LAMP (software bundle), which is driven by the reliability and security of open source software such as Linux and Apache. Some providers offer Microsoft Windows-based or FreeBSD-based solutions but both have same functionality.
There are thousands of shared hosting providers. They range from small design firms to multi-million-dollar providers with hundreds of thousands of customers. A large portion of the shared web hosting market is driven through pay per click advertising or Affiliate programs.
Shared web hosting can also be done privately by sharing the cost of running a server in a colocation centre; this is called cooperative hosting.

Shared hosting is of two types name-based and IP-based

In IP-based virtual hosting, also called dedicated IP hosting, each virtual host has a different IP address. The web server is configured with multiple physical network interfaces, or virtual network interfaces on the same physical interface. The web server software uses the IP address the client connects to in order to determine which web site to show the user.
In name-based virtual hosting, also called shared IP hosting, the virtual hosts serve multiple hostnames on a single machine with a single IP address. This is possible because when a web browser requests a resource from a web server using HTTP/1.1 it includes the requested hostname as part of the request. The server uses this information to determine which web site to show the user.
One of the most obvious setbacks of shared hosting is the price factor. Since it is very cheap, many people will not care about the disadvantages on their websites and they will want to bandwagon into these services. Due to large number of people using the services, the amount of resources that may be made available to individual users is usually limited. If one of the peer sites is using excessive amounts of the server resources, you will be facing trouble in terms of usage of your own website.
Another problem that is associated with shared hosting is the sharing of IP addresses. If you share an IP address with a company that has experienced some trouble with internet search providers, your website will also be automatically disqualified from the services of the search providers. The customer service that is provided by the companies providing the shared hosting services will also be wanton. This is because most of the companies will place greater emphasis on clients who opt for managed or individual hosting. This is because most of these clients bring in larger amounts of money and will naturally have priority.
Shared hosting plans are generally the easiest and most economical for personal and small business websites. A lot of e-commerce sites, blogs, professional portfolios, and other small sites are hosted on shared hosting.

A more recent application of the video hosting services is in the mobile web 2.0 arenas, where video and other mobile content can be delivered to, and easily accessed by mobile devices. While some video-hosting services have developed means by which video can be watched on mobile devices, mobile-oriented web-based frontends for video hosting services that possess equal access and capability to desktop oriented web services have yet to be developed. Mobile live streaming software called Qik allows the users to upload videos from their cell phones to the internet.

Videos will be stored on the servers and can be watched from both the mobile devices and the website.
It is important to choose a mobile website hosting plan carefully. The hosting provider has to be efficient. All providers cannot provide the services with best technology. If they will do any mistake or goof ups, it will certainly harm your business interest. Here are some of the facts that can help you out.
The perfect mobile website hosting plan should have the automatic device detection in place.

A database is a collection of data in tables and rows arranged in such a way that searching and retrieving the data is quick.
In most cases a database host is a specific kind of dedicated server, which is going to be used to run a database intensive application. The server can either be just for the database itself or it could also run the web site too, it really depends on how much system resources will be needed by the database. A system setup to run intense database applications will have a significant amount more RAM than a regular server.
This type of hosting is particularly useful for clients with a need to run programs such as CRM (Customer Relation Management) and ERP (Enterprise Resource Planning) software or custom-built applications. Because they typically require more memory, customers often turn to database hosting solutions to increase the speed and reliability of their applications.

The Benefits of Database Hosting

A database server is an intriguing piece of software as it has the ability to store tons of information. Unlike the average web server application, this type of server stores information in tables, which consists of columns and rows. Through the use of a database, users can get the information they need in a matter of minutes. For example, Google aims to keep its online searches below a half a second, all made possible by the more 3 trillion pages in its extensive database. What makes a database such a good source of retrieval is that it mainly pulls data out of memory opposed to a hard disk drive, something it does up to 10 times faster. Since the database is the core of the entire application, it tends to have more RAM and therefore, functions much faster than the typical web server.

Downside of Database Hosting

Similar to the software application side of a dedicated server, a database server calls for heavy administration. For this reason, it may be a good idea to go with a managed service if you lack the experience this type of hosting requires. A managed service will get you a package where the hosting provider handles some or even all of the database server administration on your behalf. These services generally range from simple management operations to more demanding tasks such as system security patching. If your plans call for a complete database server but you do not have time or skill needed to maintain it, you might be interested in a managed solution or at least one that allows you to purchase some sort of service upgrades to ease the pain of administration.

Cpanel is a UNIX based web hosting control panel that provides a graphical interface and automation tools designed to simplify the process of hosting a web site. Cpanel utilizes a 3 tier structure that provides functionality for administrators, resellers, and end-user website owners to control the various aspects of website and server administration through a standard web browser.

A colocation centre or colocation center is a type of data centre where equipment space and bandwidth are available for rental to retail customers. Colocating the server gives you the greatest flexibility. You get to choose the hardware configuration of the server and the software that goes on it. The hosting company maintains the connection to the Internet and deals with environmental details such as uninterruptible power supplies (UPSs), fire controls, and air conditioning. On the other hand, you’re responsible for that server’s upkeep.
Colocation is a hosting option for small businesses who want the features of a large IT department without the costs. Many large corporations have the Internet infrastructure to host their own web servers and have a team of IT professionals to manage and design the site. There is a wide range of options available from simple hosting up to running your own Web servers off of a dedicated Internet connection. One such option is colocation.
It is also a very good option for small businesses that want to have a fairly large Web presence but don’t want to have to deal with a large amount items such as network connections.
Companies that offer colocated hosting say they’re moving away from this service and encouraging their customers to rent a dedicated server. This means, renting an entire server from the hosting service, but having the hosting company service and maintain it.
When you opt for dedicated server colocation with the hosting company, you pay for the physical space that your server takes up. Colocation hosting usually requires a higher startup cost than renting a server from a hosting company, according to figures from Digital Nation. The server itself will cost around $4000 for a low-end model, and $9000 for a midrange server. A half-rack of space at a colocation facility will cost between $500 and $700 to start up and the same amount each month. Finally, you’ll have to purchase a switch or a router, which will cost between $1500 and $2000 at the low end. This would result in an initial outlay of at least $7500 — and it doesn’t include the costs of staff time for setup and configuration, or the cost of equipment depreciation, insurance, and the standby equipment.
Colocation allows you to place your server machine in someone else’s rack and share their bandwidth as your own. It generally costs more than standard Web hosting, but less than a comparable amount of bandwidth into your place of business. Once you have a machine set up, you take it physically to the location of the colocation provider and install it in their rack or you rent a server machine from the colocation provider. That company, then provides an IP, bandwidth, and power to your server. Once it’s up and running, you access it much like you would access a Web site on a hosting provider. The difference being that you own the hardware.
The biggest advantage of colocation is the cost for bandwidth, have better outage protection, we own the server machinery and the server software so we can upgrade the server and the software easily. If we move, we can leave the server up and running the entire time. Provide additional security for your machines.
Disadvantages of Colocation are upgrading and maintaining server is difficult, more expensive than basic Web hosting, physical access to your server can be difficult, fluctuating prices. If you move out of the area where your colocation provider is, you have to either move your servers to a new provider or leave them there and pay for a maintenance contract.
