A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet. In 2017, 330.6 million domain names had been registered.[1]

Intercapping is often used to emphasize the meaning of a domain name, because DNS names are not case-sensitive. Some names may be misinterpreted in certain uses of capitalization. For example: Who Represents, a database of artists and agents, chose whorepresents.com[23], which can be misread. In such situations, the proper meaning may be clarified by placement of hyphens when registering a domain name. For instance, Experts Exchange, a programmers' discussion site, used expertsexchange.com, but changed its domain name to experts-exchange.com.[24]
In the first quarter of 2015, 294 million domain names had been registered.[17] A large fraction of them are in the com TLD, which as of December 21, 2014, had 115.6 million domain names,[18] including 11.9 million online business and e-commerce sites, 4.3 million entertainment sites, 3.1 million finance related sites, and 1.8 million sports sites.[19] As of July 2012 the com TLD had more registrations than all of the ccTLDs combined.[20]

Web services use something known as SOAP (Simple Object Access Protocol) for sending the XML data between applications. The data is sent over normal HTTP. The data which is sent from the web service to the application is called a SOAP message. The SOAP message is nothing but an XML document. Since the document is written in XML, the client application calling the web service can be written in any programming language.

During the 32nd International Public ICANN Meeting in Paris in 2008,[10] ICANN started a new process of TLD naming policy to take a "significant step forward on the introduction of new generic top-level domains." This program envisions the availability of many new or already proposed domains, as well as a new application and implementation process.[11] Observers believed that the new rules could result in hundreds of new top-level domains to be registered.[12] In 2012, the program commenced, and received 1930 applications.[13] By 2016, the milestone of 1000 live gTLD was reached.


Shared hosting is web hosting in which the provider houses multiple sites on a single server. For example, Site A shares the same server with Site B, Site C, Site D, and Site E. The upside is that the multiple sites share the server cost, so shared web hosting is generally very inexpensive. In fact, you can find an option for less than $10 per month.
In the early 21st century, the US Department of Justice (DOJ) pursued the seizure of domain names, based on the legal theory that domain names constitute property used to engage in criminal activity, and thus are subject to forfeiture. For example, in the seizure of the domain name of a gambling website, the DOJ referenced 18 U.S.C. § 981 and 18 U.S.C. § 1955(d).[29][1] In 2013 the US government seized Liberty Reserve, citing 18 U.S.C. § 982(a)(1).[30]

ImageShack has a non-premium account option and a free 30-day trial to check out the premium features. This image hosting alternative has a great looking interface, somewhat similar to how Pinterest showcases its images in a pinboard-style layout. You can use it to upload as many high-res photos as you want, create albums, organize everything with tags and discover featured photos from other users for inspiration.

Another top site for easily sharing photos, Free Image Hosting is similar to Imgur but without the trendy layout and or the convenient hyperlink shortener. As long as you don't mind the ads all over the site, you can upload images without needing to create a free account first and Free Image Hosting provides you with the HTML code to a direct link to your photo so you can share it easily.


Many desirable domain names are already assigned and users must search for other acceptable names, using Web-based search features, or WHOIS and dig operating system tools. Many registrars have implemented domain name suggestion tools which search domain name databases and suggest available alternative domain names related to keywords provided by the user.
Some domain name registries, often called network information centers (NIC), also function as registrars to end-users. The major generic top-level domain registries, such as for the com, net, org, info domains and others, use a registry-registrar model consisting of hundreds of domain name registrars (see lists at ICANN[21] or VeriSign).[22] In this method of management, the registry only manages the domain name database and the relationship with the registrars. The registrants (users of a domain name) are customers of the registrar, in some cases through additional layers of resellers.
You can configure your privacy options if you want to share your photos with a selected audience and you have the opportunity to easily upload from a variety of platforms including via the web, your mobile device, email or other photo applications. The official Flickr mobile app is stunning and actually one of the best features of the platform. You may also want to take advantage of the Flickr Uploader tool that allows you to seamlessly backup your photos from your computer, Apple iPhoto, Dropbox and other places.
Image hosts also allow tools such as the ability to create photoblogs/galleries with your images, or add them to a slide show for easier viewing. Some offer more advanced tools such as the ability for anl to ato an image they uploaded, sideloaders, or browser sidebars. Other hosts have introduced novel features such as the ability to automatically resize images down to a user-selected size. A Flickr tool allows one to upload photos using a camera phone with email capability.[1]

A web service is a software system designed to support interoperable machine-to-machine interaction over a network. It has an interface described in a machine-processable format (specifically WSDL). Other systems interact with the web service in a manner prescribed by its description using SOAP-messages, typically conveyed using HTTP with an XML serialization in conjunction with other web-related standards.
When you want to share a photo or a gallery with friends, family, a message board, or even the entire Internet, an image hosting site is the best way to upload, store, and share your files. However, there are many image hosting sites, all with different features. The best site for you will depend on how many photos you need to upload, how much time you want to spend uploading, and the reason you’re uploading the photos.

The right to use a domain name is delegated by domain name registrars, which are accredited by the Internet Corporation for Assigned Names and Numbers (ICANN), the organization charged with overseeing the name and number systems of the Internet. In addition to ICANN, each top-level domain (TLD) is maintained and serviced technically by an administrative organization operating a registry. A registry is responsible for maintaining the database of names registered within the TLD it administers. The registry receives registration information from each domain name registrar authorized to assign names in the corresponding TLD and publishes the information using a special service, the WHOIS protocol.
ImageShack has a great interface that showcases its best photos in a layout similar to Pinterest’s. You have to create an account to upload photos, but the free account offers many helpful features. You can organize your photos into albums, and you can add tags to keep track of your images and let other users discover your work. If you don’t want the ImageShack community to view your photos, you can keep your images private or only share them with a selected audience.
Sorry Jezelll, had to throw a downvote. This is not what I would consider 'plain english' :( I don't have a problem with the intent of your definition, but using words like 'operation', 'remote server', 'invoked' and 'specification' makes it hard for beginners to understand. See Mitchel Sellers answer as an example of 'plain english'. – Dhaust Jun 30 '09 at 23:53 

The term "Web service" describes a standardized way of integrating Web-based applications using the XML, SOAP, WSDL and UDDI open standards over an Internet Protocol backbone. XML is the data format used to contain the data and provide metadata around it, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI lists what services are available.
In the case of spam, the messages often include unique image URLs that are specific to that message only. The unique URL is used as a tracking ID, so that the image host can identify exactly what message intended for what specific recipient has been viewed, in addition to the date and host accessing the image. This is why many email reading systems do not show images by default, to protect the reader from having their reading of spam being tracked by the email senders.

Before the development of image hosting services, the display and exchange of images on the early public Internet of the 1980s-1990s was a laborious and complex process. Expertise was needed to set up a private file server, to connect it to the Internet, and paying for the potentially expensive dedicated Internet connection. Some experts would provide access to a Unix shell and some file storage, via paid access, free public access, or just made available to a select group of private friends. Uploading of images was accomplished with command-line tools like FTP, or uploading images using slow 14.4 to 33.6 kilobit dialup modem connections and terminal protocols like XMODEM to the server storage.

In order to publish your website online, your business website requires a web hosting service. However, a web host gives business owners more than just web hosting services! For example, web hosting firms typically employ in-house technicians to make sure their clients' websites are up and running 24/7. Plus, when website owners are in need of help or troubleshooting (e.g. script debutting, email not able to send/receive, domain name renewal, and more), the web host's in-house support are the go-to people. A professional web hosting service ensures a hassle-free experience for business owners, so they can efficiently focus their time and effort on their businesses.

A Content Distribution Network (CDN) is a network of servers distributed geographically. The purpose of a CDN is to deliver content on the internet much faster. If a user in Toronto is trying to access your website, the closest server to them will take care of this. But someone coming to your website from Sydney, Australia, will be catered to by a server closest to them. The main host server holds your website content, and all the other servers have a cached version each.
A domain name is an identification string that defines a realm of administrative autonomy, authority or control within the Internet. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain, or it represents an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, a server computer hosting a web site, or the web site itself or any other service communicated via the Internet. In 2017, 330.6 million domain names had been registered.[1]

Domain names are formed by the rules and procedures of the Domain Name System (DNS). Any name registered in the DNS is a domain name. Domain names are organized in subordinate levels (subdomains) of the DNS root domain, which is nameless. The first-level set of domain names are the top-level domains (TLDs), including the generic top-level domains (gTLDs), such as the prominent domains com, info, net, edu, and org, and the country code top-level domains (ccTLDs). Below these top-level domains in the DNS hierarchy are the second-level and third-level domain names that are typically open for reservation by end-users who wish to connect local area networks to the Internet, create other publicly accessible Internet resources or run web sites.
Before the Web was developed, images would primarily be downloaded manually from file servers or from binary newsgroups on Usenet, and displayed with a separate image viewer. The expansion of the Web in the 1990s brought text and images together, allowing for inline display of images without separate downloading, but still required the above expertise and methods to make the images available.
Intercapping is often used to emphasize the meaning of a domain name, because DNS names are not case-sensitive. Some names may be misinterpreted in certain uses of capitalization. For example: Who Represents, a database of artists and agents, chose whorepresents.com[23], which can be misread. In such situations, the proper meaning may be clarified by placement of hyphens when registering a domain name. For instance, Experts Exchange, a programmers' discussion site, used expertsexchange.com, but changed its domain name to experts-exchange.com.[24]
