A domain name sends a signal to internet users and search engines. Whether you plan to use it primarily as an e-commerce site, the online presence of a brick-and-mortar business, a marketing campaign or a custom email address, it’s a term that will define you. So why do you need to buy a domain in the first place? For one, having a registered domain name and site-specific email address adds credibility to your brand. It also makes it easier for customers, readers, or users to find your site, and provides control over what search engine users see when they search your company, organization, or name. You can change your hosting provider, site design, and even what your site does, but your domain name will stay the same unless you purchase another one.
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
In practice, a Web service commonly provides an object-oriented Web-based interface to a database server, utilized for example by another Web server, or by a mobile app, that provides a user interface to the end-user. Many organizations that provide data in formatted HTML pages will also provide that data on their server as XML or JSON, often through a Web service to allow syndication, for example, Wikipedia's Export. Another application offered to the end-user may be a mashup, where a Web server consumes several Web services at different machines and compiles the content into one user interface.

You want your domain name to be easy for people to remember and easy for people to type. It’s usually best if it speaks to the service or products your site offers; if it’s a website for your business, it’s best if the domain includes either the company name or the keywords relevant to your business. Poke around similar and competing websites. Avoid awkward spellings, special characters, and numbers wherever possible. Ask friends, family members, and colleagues for their opinions as you brainstorm. Then, look on social media platforms to ensure the name isn’t in use elsewhere and go to www.uspto.gov to check for any trademark infringement issues.

A web service always hides the internal complexity of the service to its clients. For an example, an airliner which is selling tickets via a third party portal is only gathering end user info via a web service and in return it is providing ticket. The portal which is selling ticket doesn't have to bother about the internal complexity of the airlines ticket reservation systems.


SOAP is known as a transport-independent messaging protocol. SOAP is based on transferring XML data as SOAP Messages. Each message has something which is known as an XML document. Only the structure of the XML document follows a specific pattern, but not the content. The best part of Web services and SOAP is that its all sent via HTTP, which is the standard web protocol. 

A web service is a collection of open protocols and standards used for exchanging data between applications or systems. Software applications written in various programming languages and running on various platforms can use web services to exchange data over computer networks like the Internet in a manner similar to inter-process communication on a single computer. This interoperability (e.g., between Java and Python, or Windows and Linux applications) is due to the use of open standards (XML, SOAP, HTTP).

When you build a website, you want visitors to come and see what you've done. To get them there, you need a unique domain name that connects to your sites servers. Domain name registration is required to ensure that no one else in the world can claim ownership of your web site's address and to make finding your website simple. Find your one of a kind domain name.

Domain registrar discounts. Oftentimes, these sites will provide a special price at different times of the year or if you purchase multiple aspects of their service. Generally, shorter domains with well-known words cost more. Completely original names typically range between $2 and $20 per year. However, domain name prices fluctuate often. The price for the same name could even be different from one registrar to another. Appraisal sites like estibot can help you get an estimate for the current cost of any given name. The more flexible you are about the name, the better deal you’re likely to get. You can also pay more for extra benefits, like private domain registration. Usually around $10 or $15 a year, this protects your private information (like email address, home address, telephone number, and ownership details stored in WHOIS) from the general public.
Synchronous or Asynchronous functionality- Synchronicity refers to the binding of the client to the execution of the service. In synchronous operations, the client will actually wait for the web service to complete an operation. An example of this is probably a scenario wherein a database read and write operation are being performed. If data is read from one database and subsequently written to another, then the operations have to be done in a sequential manner. Asynchronous operations allow a client to invoke a service and then execute other functions in parallel. This is one of the common and probably the most preferred techniques for ensuring that other services are not stopped when a particular operation is being carried out.

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.
