What is a web application and for which businesses it is used?

With the spread of mobile phones, almost all of us are somewhat familiar with the concept of applications. But web application is one of those terms that may tickle your mind and search for its meaning. Web application, or in short, web app, is similar to the software that we all install on our laptops or computers. It means it does something for us. Take, for example, your computer calculator. Now, if this tool for performing mathematical operations uses the web platform and the Internet to do its work; It becomes a web application.
Well, now you may have been asked why you should use a web application instead of providing software or designing an offline mobile application. The answer is hidden in the number of times the software is used. In other words, none of us likes the message that there is not enough space available to record a memorable video; on the other hand, we don't need to convert our date of birth from Hijri to Gregorian every day. So if we install such software on our mobile phone; We occupy a space of our phone that could occupy the place of an interesting video and worse, we don't need what this application does for us for many days.
The solution here is to use a web application or web-based software. These software do not need to be installed and are stored on a server and offer their services to us online.
Apart from the user's point of view, if we put ourselves in the place of the service provider, our preference is to provide the most convenient type of service to our customers. Let's say we are a hardware seller and we have listed the price of one kilogram of each metal on our site, and of course, we have given discounts to our customers. The customer enters our site and intends to buy 4732 kg of iron. Naturally, every buyer wants to know what the final price of the purchase will be. One way is to provide the price table per kilo of metals and the table of discounts to the customer so that he can do the necessary calculations and get the final price. We all are always looking for an easier way to do our jobs and on the other hand, our competitors are using web applications on their site. That is, the customer can enter the amount of metal he wants in a box and immediately see its price including discounts. It is optimistic to think that the customer will stay on our site and do the calculations himself. So it is better that we also have a web application on our site and of course, we know the nature and function of the web application well so that we do not lose our customers easily.

What is a web application?

Web application is the software that does not need to be installed and provides its services to customers through the web and the Internet. You may think that with these words, there is no need to download the application and install the software; But remember that web app requires the internet. That is, if you are not online, you cannot use the web software.
Some applications are so widely used that there is no other way but to install them. Of course, remember that offline applications and software usually work faster than web-based software.
As soon as the application uses the internet platform to perform its work and provide service, it becomes a web application. It doesn't matter what the app does. The range of software on the web can be expanded from a simple calculator to heavy programs such as Photoshop online and Internet games.

How does the web application work?

Let's first check how simple software like a calculator works in a very simple way. This software has a database that includes codes and algorithms. These codes and algorithms provide you with tools. For example, in the case of the calculator, tools such as addition, subtraction, multiplication, division, square root, power, etc. are available to you through these codes.
You need to install the program on your system and then start interacting with the program. That is, provide the program with data as input, for example, you want to add the numbers two to three. Numbers two and three are the inputs through which you interact with the software, and summation is the tool you use through the database code. Finally, you get the output which is the sum of your inputs. Of course, the type of input is determined by the software. For example, you cannot use words as input to a calculator.
This process is completely repeated in the case of more complex software, for example, in Photoshop, the tools provided by the database codes are zooming, removing the background, image effects, determining the amount of light, etc. Your input is a photo and the output is an edited photo.
Now let's go to the web application. The web application or web app also goes through the same processes, with the difference that the database codes are not installed on your system and are stored on a server. Your input is sent to the server through the Internet, and you determine the tool you need, and then the output is sent to you on the web platform. The main point of the web application is not to install a database on the system but to use the Internet platform to perform the process and receive and send input and output.

Some sites only contain a web application, for example, sites that can be used to design a logo online. Or sites that remove the background of your photo.
