A web-Based Application or a Web App is a program that is accessed over a connection of networks formed using HTTP. It does not need space in device memory. Web-based Applications are also called Web Apps.
Let’s discuss Web-based applications in detail-
In simple words, an application can be defined as a program or set of programs that have been designed for the user. These computer programs are designed for a specific function.
There are two broadly classified types of applications-
These are the applications that need to be installed on our systems. They require OS services to work on your computer i.e- operating system’s services. They do not necessarily require net connectivity or a web browser for running. It uses the user’s RAM and space from their computer.
Example- MS Word, MS Powerpoint, etc.
As we understand the meaning of a standalone application, it will be easy to understand web-based applications.
Web-based applications run inside a web browser. Example- Google chrome, UC browser, Internet Explorer, etc. They are most likely to be client-based applications; one end is opened on the user’s screen which he/she uses to interact with the webserver but all the processing is done via the internet connection.
Some basic examples for web-based applications are online calculators, calendars, mp3 and mp4 convertors, music downloading sites, etc. Word processors, Spreadsheet applications are big examples of web-based applications.
This client-server side software program that is stored at the webserver does not require installation for use. It has the fastest access worldwide.
Web-based applications deal with several clients at the same time. The client uses a web browser and net connection to establish a network with the application’s server. Many clients can connect to the application’s server at the same time by using different web browsers and the internet on their end. The server of the application i.e- The web Server has the source code.
For example- Netflix, Facebook, and Gmail have their source code present on the webserver. It needs the internet and a browser to get access.
There are many advantages of a web application. Some of them are-
When there are two parties involved they always work concerning some protocols. Protocols are a set of rules that both parties have to follow. Some standard protocols are HTTP, FTP, and Web Socket.
HTTP is the most commonly used protocol in web applications. FTP is also a protocol for transferring files.
When a web application is developed, there are a lot of testing issues, security problems, and overall performance that are to be considered. Testing tools are very essential. Here are some of them-
Link Manager Testing Tools- Websites are made of links. A wrong link can take you to some wrong page and you might end up messing the whole process. Link manager helps to manage this problem. Testing tools for it are-
Security Tools for websites are-
Web Applications can be very interesting and informative for people who love technology.
