FAQ

What is an example of web services application?

At Netcorp, our expertise spans across various web service applications such as XML, UDDI, SOAP, and REST. With 12 years under our belt, we’re committed to delivering top-notch services tailored to your needs.

What is the difference between Webapp and app service?

Think of a web application as the house you live in, and the app service as the land it’s built on. The web application is the program that users interact with, while the app service provides the infrastructure for it to be accessed online.

What is the difference between regular app development and web app development?

Regular app development can cater to a range of devices and might not always need internet access. On the other hand, web app development specifically crafts applications meant to be accessed and used over the internet, hosted by a dedicated app service.

What language is used for web application development?

The choice of language for web application development often hinges on the specific requirements of the project. Popular options include .NET, Java, PHP, Node.js, and Python, all of which we’re proficient in at Netcorp.

… and many more.
