A web hosting service is a type of Internet hosting service An Internet hosting service is a service that runs Internet servers, allowing organizations and individuals to serve content to the Internet. There are various levels of service and various kinds of services offered that allows individuals and organizations to make their own website A website [citation needed] is a collection of related web pages, images, videos or other digital assets that are addressed relative to a common Uniform Resource Locator (URL), often consisting of only the domain name, or the IP address, and the root path ('/') in an Internet Protocol-based network. A web site is hosted on at least one web server, accessible via the World Wide Web The World Wide Web, abbreviated as WWW and commonly known as the Web, is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them by using hyperlinks. Using concepts from earlier hypertext systems, British. Web hosts are companies that provide space on a server In computing, a server is any combination of hardware or software designed to provide services to clients. When used alone, the term typically refers to a computer which may be running a server operating system, but is also used to refer to any software or dedicated hardware capable of providing services they own or lease for use by their clients as well as providing Internet The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and connectivity, typically in a data center A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and security devices. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center, called colocation.
The scope of hosting services varies widely. The most basic is web page A web page or webpage is a document or resource of information that is suitable for the World Wide Web and can be accessed through a web browser and displayed on a monitor or mobile device and small-scale file hosting, where files can be uploaded In networks, to download means to receive data to a local system from a remote system, or to initiate such a data transfer. Examples of a remote system might from which a download might be performed include a webserver, FTP server, email server, or other similar systems. A download can mean either any file that is offered for downloading or that via File Transfer Protocol File Transfer Protocol is a standard network protocol used to copy a file from one host to another over a TCP/IP-based network, such as the Internet. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server applications, which solves the problem of different end host (FTP) or a Web interface. The files are usually delivered to the Web "as is" or with little processing. Many Internet service providers An Internet service provider , also sometimes referred to as an Internet access provider (IAP), is a company that offers its customers access to the Internet[citation needed]. The ISP connects to its customers using a data transmission technology appropriate for delivering Internet Protocol Paradigm, such as dial-up, DSL, cable modem, wireless or (ISPs) offer this service free to their subscribers. People can also obtain Web page hosting from other, alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense.
Single page hosting is generally sufficient only for personal web pages Personal web pages are World Wide Web pages created by an individual to contain content of a personal nature rather than on behalf of an employer or institution. Personal web pages are often used solely for informative or entertainment purposes. A complex site calls for a more comprehensive package that provides database A database consists of an organized collection of data for one or more uses, typically in digital form. One way of classifying databases involves the type of their contents, for example: bibliographic, document-text, statistical. Digital databases are managed using database management systems, which store database contents, allowing data creation support and application development platforms (e.g. PHP PHP: Hypertext Preprocessor is a widely used, general-purpose scripting language that was originally designed for web development to produce dynamic web pages. For this purpose, PHP code is embedded into the HTML source document and interpreted by a web server with a PHP processor module, which generates the web page document. As a general-purpose, Java Java refers to a number of computer software products and specifications from Sun Microsystems, a subsidiary of Oracle Corporation, that together provide a system for developing application software and deploying it in a cross-platform environment. Java is used in a wide variety of computing platforms from embedded devices and mobile phones on the, Ruby on Rails Ruby on Rails, often shortened to Rails or RoR, is an open source web application framework for the Ruby programming language. It is intended to be used with an Agile development methodology that is used by web developers for rapid development, ColdFusion ColdFusion is a commercial rapid application development platform invented by Jeremy and JJ Allaire in 1995. Originally designed to make it easier to connect simple HTML pages to a database, by version 2 it had become a full platform that included an IDE in addition to a full Scripting Language. Current versions of ColdFusion, sold by Adobe, and ASP.NET ASP.NET is a web application framework developed and marketed by Microsoft to allow programmers to build dynamic web sites, web applications and web services. It was first released in January 2002 with version 1.0 of the .NET Framework, and is the successor to Microsoft's Active Server Pages technology. ASP.NET is built on the Common Language). These facilities allow the customers to write or install scripts for applications like forums An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages. They differ from chat rooms in that messages are not shown in real-time, to see new messages the forum page must be reloaded. Also, depending on the access level of a user and/or the forum set-up, a posted message and content management Content management, or CM, is the set of processes and technologies that support the collection, managing, and publishing of information in any form or medium. In recent times this information is typically referred to as content or, to be precise, digital content. Digital content may take the form of text, such as documents, multimedia files, such. For e-commerce Electronic commerce, commonly known as e-commerce or eCommerce, consists of the buying and selling of products or services over electronic systems such as the Internet and other computer networks. The amount of trade conducted electronically has grown extraordinarily with widespread Internet usage. The use of commerce is conducted in this way,, SSL Transport Layer Security and its predecessor, Secure Socket Layer (SSL), are cryptographic protocols that provide security for communications over networks such as the Internet. TLS and SSL encrypt the segments of network connections at the Transport Layer end-to-end is also highly recommended.
The host may also provide an interface or control panel Categories: Web hosting | Web server management software for managing the Web server A web server is a computer program that delivers content, such as web pages, using the Hypertext Transfer Protocol (HTTP), over the World Wide Web. The term web server can also refer to the computer or virtual machine running the program and installing scripts as well as other services like e-mail. Some hosts specialize in certain software or services (e.g. e-commerce). They are commonly used by larger companies to outsource network infrastructure to a hosting company.

Hosting uptime Uptime is a measure of the time a machine has been up without any downtime refers to the percentage of time the host is accessible via the internet. Many providers state that they aim for at least 99.9% uptime (roughly equivalent to 45 minutes of downtime a month, or less), but there may be server restarts and planned (or unplanned) maintenance in any hosting environment, which may or may not be considered part of the official uptime promise.
Many providers tie uptime and accessibility into their own service level agreement (SLA). SLAs sometimes include refunds or reduced costs if performance goals are not met.
Types of hosting
A typical server "rack," commonly seen in colocation centres A colocation centre ("colo") or carrier hotel is a type of data centre where multiple customers locate network, server and storage gear and interconnect to a variety of telecommunications and other network service provider(s) with a minimum of cost and complexity. Most network access point facilities provide colocation.Internet hosting services can run Web servers A web server is a computer program that delivers content, such as web pages, using the Hypertext Transfer Protocol (HTTP), over the World Wide Web. The term web server can also refer to the computer or virtual machine running the program. In large commercial deployments, a server computer running a web server can be rack-mounted with other servers; see Internet hosting services An Internet hosting service is a service that runs Internet servers, allowing organizations and individuals to serve content to the Internet. There are various levels of service and various kinds of services offered.
Hosting services limited to the Web:
Many large companies who are not internet service providers also need a computer permanently connected to the web so they can send email, files, etc. to other sites. They may also use the computer as a website host so they can provide details of their goods and services to anyone interested. Additionally these people may decide to place online orders.
- Free web hosting service A free web hosting service is a web hosting service that is free, usually advertisement-supported. Free web hosts will usually provide a subdomain or a directory (www.example.com/~yourname). In contrast, paid web hosts will usually provide a second-level domain along with the hosting (www.yourname.com). Many free hosts do allow use of separately-: offered by different companies with limited services, sometimes supported by advertisements, and often limited when compared to paid hosting.
- Shared web hosting service 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 "sits" on its own partition, or section/place on the server to keep it separate from other sites. This is generally the most economical option for hosting,: one's website is placed on the same server as many other sites, ranging from a few to hundreds or thousands. Typically, all domains may share a common pool of server resources, such as RAM Random-access memory is a form of computer data storage. Today, it takes the form of integrated circuits that allow stored data to be accessed in any order (i.e., at random). "Random" refers to the idea that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the and the CPU The central processing unit or the processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. It is the unit that reads and executes program instructions. The data in the instruction tells the processor what to do. The instructions are. The features available with this type of service can be quite extensive. A shared website may be hosted with a reseller.
- Reseller web hosting: allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a provider. Resellers' accounts may vary tremendously in size: they may have their own virtual dedicated server to a collocated server. Many resellers provide a nearly identical service to their provider's shared hosting plan and provide the technical support themselves.
- Virtual Dedicated Server A virtual private server is a method of splitting a server. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted: also known as a Virtual Private Server (VPS), divides server resources into virtual servers, where resources can be allocated in a way that does not directly reflect the underlying hardware. VPS will often be allocated resources based on a one server to many VPSs relationship, however virtualisation may be done for a number of reasons, including the ability to move a VPS container between servers. The users may have root access to their own virtual space. Customers are sometimes responsible for patching and maintaining the server.
- Dedicated hosting service A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server, including choice of operating system, hardware, etc. Server administration can: the user gets his or her own Web server and gains full control over it (root access for Linux/administrator access for Windows); however, the user typically does not own the server. Another type of Dedicated hosting is Self-Managed or Unmanaged. This is usually the least expensive for Dedicated plans. The user has full administrative access to the box, which means the client is responsible for the security and maintenance of his own dedicated box.
- Managed hosting service A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server, including choice of operating system, hardware, etc. Server administration can: the user gets his or her own Web server but is not allowed full control over it (root access for Linux/administrator access for Windows); however, they are allowed to manage their data via FTP or other remote management tools. The user is disallowed full control so that the provider can guarantee quality of service by not allowing the user to modify the server or potentially create configuration problems. The user typically does not own the server. The server is leased to the client.
- Colocation web hosting service A colocation centre ("colo") or carrier hotel is a type of data centre where multiple customers locate network, server and storage gear and interconnect to a variety of telecommunications and other network service provider(s) with a minimum of cost and complexity. Most network access point facilities provide colocation: similar to the dedicated web hosting service, but the user owns the colo server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's machine, providing only the electrical, Internet access, and storage facilities for the server. In most cases for colo, the client would have his own administrator visit the data center on site to do any hardware upgrades or changes.
- Cloud Hosting: is a new type of hosting platform that allows customers powerful, scalable and reliable hosting based on clustered load-balanced servers and utility billing. Removing single-point of failures and allowing customers to pay for only what they use versus what they could use.
- Clustered hosting: having multiple servers hosting the same content for better resource utilization. Clustered Servers are a perfect solution for high-availability dedicated hosting, or creating a scalable web hosting solution. A cluster may separate web serving from database hosting capability.
- Grid hosting Grid computing is a term referring to the combination of computer resources from multiple administrative domains to reach common goal. What distinguishes grid computing from conventional high performance computing systems such as cluster computing is that grids tend to be more loosely coupled, heterogeneous, and geographically dispersed. Although: this form of distributed hosting is when a server cluster acts like a grid and is composed of multiple nodes.
- Home server A home server is a server located in a private residence providing services to other devices inside and/or outside the household through a home network and/or the internet. Such services may include file and/or printer serving, media center serving, web serving, web caching, account authentication and backup services. Because of the relatively low: usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband The term broadband refers to a telecommunications signal of greater bandwidth, in some sense, than another standard or usual signal . Different criteria for "broad" have been applied in different contexts and at different times. Its origin is in radio systems engineering, but became popularized after MediaOne adopted it as part of a connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP The Transmission Control Protocol is one of the core protocols of the Internet Protocol Suite. TCP is one of the two original components of the suite (the other being Internet Protocol, or IP), so the entire suite is commonly referred to as TCP/IP. Whereas IP handles lower-level transmissions from computer to computer as a message makes its way port 80 of the user's connection and by refusing to provide static IP addresses. A common way to attain a reliable DNS hostname is by creating an account with a dynamic DNS Dynamic DNS is a method, protocol, or network service that provides the capability for a networked device, such as a router or computer system using the Internet Protocol Suite, to notify a domain name server to change, in real time the active DNS configuration of its configured hostnames, addresses or other information stored in DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.
Some specific types of hosting provided by web host service providers:
- File hosting service A file hosting service, online file storage provider or cyberlocker is an Internet hosting service specifically designed to host static content, typically large files that are not web pages. Typically they allow web and FTP access. They can be optimized for serving many users or be optimized for single-user storage (as is implied by the term ": hosts files, not web pages
- Image hosting service An image hosting service allows individuals to upload images to an Internet website. The image host will then store the image onto its server, and show the individual different types of code to allow others to view that image
- Video hosting service A video hosting service allows individuals to upload video clips to an Internet website. The video host will then store the video on its server, and show the individual different types of code to allow others to view this video. The website, mainly used as the video hosting website, is usually called the video sharing website
- Blog hosting service Weblog software is software designed to simplify the creation and maintenance of weblogs. As specialized content management systems, weblog applications support the authoring, editing, and publishing of blog posts and comments, with special functions for image management, web syndication, and moderation of posts and comments
- One-click hosting A file hosting service, online file storage service, or online media center is an Internet hosting service specifically designed to host static content, typically large files that are not web pages. Typically they allow web and FTP access. They can be optimized for serving many users or be optimized for single-user storage (as is implied by the
- Pastebin A pastebin is a web application which allows its users to upload snippets of text, usually samples of source code, for public viewing. It is very popular in IRC channels where pasting large amounts of text is considered bad etiquette. A vast number of pastebins exist on the Internet, suiting a number of different needs and provided features Hosts text snippets
- Shopping cart software Shopping cart software is software used in e-commerce to assist people making purchases online, analogous to the American English term 'shopping cart'. In British English it is generally known as a shopping basket, almost exclusively shortened on websites to 'basket'
- E-mail hosting service E-mail hosting services usually offer premium e-mail at a cost as opposed to advertising supported free e-mail or free webmail. E-mail hosting services thus differ from typical end-user e-mail providers such as webmail sites. They cater mostly to demanding e-mail users and Small and Mid Size businesses, while larger enterprises usually run their
Obtaining hosting
Web hosting is often provided as part of a general Internet access plan; there are many free and paid providers offering these services.
A customer needs to evaluate the requirements of the application to choose what kind of hosting to use. Such considerations include database server software, scripting software, and operating system An operating system is the software on a computer that manages the way different programs use its hardware, and regulates the ways that a user controls the computer. Operating systems are found on almost any device that contains a computer with multiple programs—from cellular phones and video game consoles to supercomputers and web servers. Some. Most hosting providers provide Linux-based web hosting which offers a wide range of different software. A typical configuration for a Linux server is the LAMP LAMP is an acronym for a solution stack of free, open source software, originally coined from the first letters of Linux used for the operating system, Apache HTTP Server, MySQL , and PHP (web scripting language), principal components to build a viable general purpose web server platform: Linux, Apache, MySQL, and PHP/Perl/Python. The webhosting client may want to have other services, such as email for their business domain, databases or multi-media services for streaming media. A customer may also choose Windows as the hosting platform. The customer still can choose from PHP, Perl, and Python but may also use ASP .Net or Classic ASP. Web hosting packages often include a Web Content Management System, so the end-user doesn't have to worry about the more technical aspects.

Q. Do you have any good or bad experience with 1 And 1 web hosting service?
Asked by JQT - Mon May 4 04:34:36 2009 - - 6 Answers - 0 Comments
A. I tried them out temporarily a few years ago and found the following problems then: 1. If you have a .com domain, the nameservers for 1&1 are not in the UK and so you are unlikely to find yourself in the Google UK specific search results. 2. They tagged mail rather than filtered it, meaning that if you download mail on your phone, you still have to pay to download the spam. 3. You couldn't pay by direct debit. 4. The quality of their English was poor (customer support) 5. Leaving the service was a loathsome and difficult process. I switched to www.xcalibre.co.uk and have no complaints.
