Web service is a standard medium for spreading communication between client and server applications on the World Wide Web (www). Web services are software modules designed to perform a specific set of tasks. Here’s a full explanation.
For example, when you create a website in PHP that generates HTML, the target is the browser, and by extension, a human reads the page in the browser. Web services are not targeted at humans but other programs.
So your PHP site that generates random integers can become a web service if it generates integers in a format that other programs can consume. It may be in XML or some other form, as long as other programs understand the result.
What is Web Service?
Web services are web-based software applications that exchange data with other web-based applications. The Open standard, Extensible Markup Language (XML) and various other protocols are used for this exchange. This service is used in more significant private network interactions in its original capacity. Today, however, they include interaction over the internet as well.
Integral to web services, XML is a web document description language. XML is used to describe the content of web pages using the application of hidden tags and identifying labels.

This method of web data classification is very effective, making web content relatively easy to identify, analyze and exchange.
Web services are self-contained, modular, circulated, dynamic applications that can be defined, published, discovered, or contacted over a network to create products, processes, and supply chains.
These applications can be local, distributed, or web-based. Web services are built on open standards such as TCP/IP, HTTP, Java, HTML, and XML.
Use of Web Service
Web services are helpful in connecting applications that operate on different network platforms, hardware, software and databases, performing essential functions for many businesses.
For example, they can provide optimal interaction between specific business functions and critical applications shared with an organization’s customers, partners, and vendors.
This service is also helpful for combining software and services from different companies to provide seamlessly integrated services.
Web services offer many benefits, including, but not limited to, easy understanding. Processes and data are often text-based to ensure methods and data are as simple as possible for developers to understand.
Thanks to the access provided by XML, developers dealing with various technologies can use web services.
A web service is a collection of open and standard protocols used to exchange data between applications or systems. Software applications written in various programming languages and running on multiple platforms can use web services to exchange data over computer networks such as the internet, like communication between processes on a single computer.
This interoperability (e.g. between Java and Python or Windows and Linux applications) is due to open standards.
Another benefit of this service, as opposed to other technologies, involves a firewall.
There is no need to change the firewall filtering system with web services. This is because web services using HTTP can work relatively quickly through the most commonly used firewall security measures.
