Every website on the internet has a unique IP address assigned to it, made up of a series of numbers. These numbers tell the domain name system (DNS) to locate the corresponding website. As we are humans and not computers, IP addresses are difficult to remember and so words are used instead. These words are known as the domain or URL. The DNS looks at the domain name and translates it into an IP address.
Unlike traditional client/server models, such as a Web server/Web page system, Web services do not provide the user with a GUI. Web services instead share business logic, data and processes through a programmatic interface across a network. The applications interface, not the users. Developers can then add the Web service to a GUI (such as a Web page or an executable program) to offer specific functionality to users.
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.
Loosely Coupled – Loosely coupled means that the client and the web service are not bound to each other, which means that even if the web service changes over time, it should not change the way the client calls the web service. Adopting a loosely coupled architecture tends to make software systems more manageable and allows simpler integration between different systems.

Without prejudice to other definitions I would say that a web service is software system that allows for inter-operable machine-to-machine / application-to-application interaction over a network. This generic definitions would also help consider REST architectures to be a web service as they provide similar functionality albeit being an architectural style unlike the SOAP which is a fully defined protocol.

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

A web service is something that a website chooses to offer to those who wish to read, update and/or delete data from your website. You might call it a "backdoor" to your data. Instead of presenting the data as part of a webpage it is provided in a pre-determined way where some of the more popular are XML and JSON. There are several ways to communicate with a webservice, some use SOAP, others have REST'ful web services, etc.
Welcome to the CNET 2020 directory of web hosting services. In this directory, we'll look at a few of the best web hosting providers like Bluehost, A2Hosting, Hostinger, DreamHost, HostGator, InMotion Hosting and more. In this evaluation of the best web hosting providers, we're featuring commercial web hosting companies that offer WordPress, VPS, shared hosting and many more web hosting services, along with a variety of annual and monthly plans.     
Domain names are created to make IP addresses easy to remember. Every computer has an IP address assigned to it - much like a street address. But instead of having to memorize each IP address number, we assign domain names to these numbers so we can easily remember them. The domain name system, or DNS, takes domain names and translates them into their IP addresses so that computers can communicate with one another.
Interoperability amongst applications - Web services allow various applications to talk to each other and share data and services among themselves. All types of applications can talk to each other. So instead of writing specific code which can only be understood by specific applications, you can now write generic code that can be understood by all applications

For more business-oriented customers, it offers a full range of VPS and cloud hosting, along with serious Java Tomcat hosting, including shared and private JVMs, as well as Java VPS offerings. With a company named MochaHost, you'd expect some quality Java support and it has it. So brew yourself a cuppa, open a browser window and give MochaHost a spin. You have half a year to make up your mind, so if it turns out MochaHost really isn't your cup of tea, it'll understand.
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.
The Internet Corporation for Assigned Names and Numbers (ICANN) is the organization that governs the rules and regulations for domain name registrations. ICANN requires, for various reasons including to determine ownership of a domain should a dispute transpire, that a publicly accessible database be maintained that contains the contact information of all domain registrants. In layman's terms this means your domain name will be searchable by anyone and those search results will include your full name, physical address and other contact information. In order to protect your privacy in this regard, Domain.com offers WHOIS Domain Privacy which then masks your information using our own and implements a procedure for you to control who is able to then gain access to your contact information via a WHOIS search. Whenever you buy a domain name, no matter what domain name registration service you use, you are subject to the same ICANN rules, for this reason it is important to use a reputable service who cares about your privacy. Domain.com always recommends enabling WHOIS Domain Privacy.

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).
With Imgur, you can store an unlimited number of photos without worrying about your photos expiring. You don’t need an account to upload photos to Imgur, but you can create a free account if you want to create albums, add captions, and upload your images via email attachments. They allow direct linking, and they give you a link for each image to post it in forums or embed it in HTML.
The first thing that caught our eye about Complete Internet Hosting was a great answer to my biggest complaint about hosting providers. Most hosting providers will suck you in with a relatively aggressive starting price, but when it comes time to renew, the renewal price can be two or three times the original price. I've even found one company that renews at more than six times the original price.
You get other customer-centric bonuses for 24/7 customer support, including 24/7 toll-free callback phone support, free domain name and SSL certificates for as long as you remain a MochaHost customer, a website builder with 500 free templates (and a service that will custom-design your site if you need) and a site migration service. In addition, all plans are e-commerce ready and come with free shopping cart software.
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. 

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.
The company doesn't list a virtual private server offering, but it bills its Elastic Sites service as a VPS alternative, offering the ease of use of a simple shared hosting plan and the performance and scalability of a VPS. GlowHost also offers a number of different cloud hosting plans, with special attention to providing enterprise-grade services.
On the plus side, SiteGround offers free automatic daily backups, access to the Cloudflare CDN, high-performance SSDs for all plans, unlimited email accounts and integration of the free LetsEncrypt SSL certificate into sites. The company does limit bandwidth and storage, but even those who claim to offer so-called unlimited bandwidth and storage really have some limits in its terms of service.
Now we discussed in the previous topic about WSDL and how it contains information on what the Web service actually does. But how can a client application locate a WSDL file to understand the various operations offered by a web service? So UDDI is the answer to this and provides a repository on which WSDL files can be hosted. So the client application will have complete access to the UDDI, which acts as a database containing all the WSDL files.

Web services architecture: the service provider sends a WSDL file to UDDI. The service requester contacts UDDI to find out who is the provider for the data it needs, and then it contacts the service provider using the SOAP protocol. The service provider validates the service request and sends structured data in an XML file, using the SOAP protocol. This XML file would be validated again by the service requester using an XSD file.

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.

A directory called UDDI (Universal Description, Discovery, and Integration) defines which software system should be contacted for which type of data. So when one software system needs one particular report/data, it would go to the UDDI and find out which other systems it can contact for receiving that data. Once the software system finds out which other systems it should contact, it would then contact that system using a special protocol called SOAP (Simple Object Access Protocol). The service provider system would first validate the data request by referring to the WSDL file, and then process the request and send the data under the SOAP protocol.

One option not mentioned in the article is Amazon Photos. Even though I’m an Amazon “prime” customer, I had never really given their photo storage much thought because I already had several sites I use for photo sharing and storage. However, I recently learned that they will store your photos in their original size AND your RAW (CR2, NEF, ARW….) photos too! This is a HUGE advantage for me.
When it comes to server operating systems, Linux is typically the default option. Still, some services offer a choice of Linux or Windows hosting. If you have specific server-side applications that require Windows, such as SQL Server or a custom application written in .NET, then you need to make sure your web host has Windows hosting. But don't let the idea of a Linux host intimidate you. Nowadays, most web hosts offer a graphical interface or a control panel to simplify server administration and website management. Instead of typing at the command line, you'll click easily identifiable icons.
TinyPic is owned by Photobucket, so it offers many of the same features. However, you don’t need to create an account to upload photos, so you can quickly and easily upload a photo for sharing. To upload a photo, you simply select the image, add tags if you want to, and set the size of the photo. You’ll get a link that you can use to share a photo anywhere. The optional tags will allow TinyPic users to find your photos through a search.
Flickr is also a social networking site, so you can share your photos with the entire Flickr community. There are many groups for different interests and topics, including nature, black and white photography, and fashion. Users can favorite others’ photos and leave comments. If you want more privacy, you can edit your privacy settings so you’ll only share photos with selected individuals.

The term Web services 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 used to tag the data, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI is used for listing what services are available. Used primarily as a means for businesses to communicate with each other and with clients, Web services allow organizations to communicate data without intimate knowledge of each other's IT systems behind the firewall.
