Does a Web Based Application Run on a Server?
When you use a web based application, have you ever wondered where the application actually runs? Well, the answer lies in the server. A web based application indeed runs on a server.
What is a web based application?
A web based application, also known as a web app, is an application that is accessed through a web browser over the internet. It eliminates the need for installing software on individual devices and provides users with a convenient way of accessing services or using software without worrying about compatibility issues.
How does it work?
When a user opens a web app in their browser, the request is sent to a server where the application is hosted. The server processes the request and sends back the necessary files and data to be displayed in the user’s browser. This interaction between the browser and the server allows users to interact with and use the web app.
Why does it run on a server?
A server plays a crucial role in running web based applications for several reasons:
- Processing Power: Servers are designed to handle multiple requests simultaneously. They have high processing power, allowing them to process complex tasks efficiently.
- Data Storage: Servers provide ample storage space for storing data that is required by the web app.
This includes user information, files, configurations, and more.
- Security: Servers offer enhanced security measures to protect sensitive data from unauthorized access or attacks. They can implement firewalls, encryption, and other security protocols to ensure the safety of the web app and its users.
- Scalability: As web apps grow in popularity and attract more users, servers can be scaled up to accommodate increased traffic and demand. This scalability ensures that the web app remains accessible and performs well even during peak usage periods.
Types of servers used for web based applications
There are different types of servers that can be used to host web based applications:
1. Web Server:
A web server is responsible for handling HTTP requests from clients (browsers) and serving them with the requested resources. It interprets HTTP requests, retrieves the necessary files or data, and sends them back as a response. Popular examples of web servers are Apache HTTP Server, Nginx, and Microsoft IIS.
2. Application Server:
An application server is designed to handle the execution of application logic. It provides an environment for running server-side scripts or applications that process data and generate dynamic content. Application servers often work in conjunction with a web server to deliver the final output to the user’s browser.
3. Database Server:
A database server stores and manages data required by the web based application. It allows for efficient storage, retrieval, modification, and deletion of data using structured query language (SQL). Commonly used database servers include MySQL, Oracle Database, and Microsoft SQL Server.
In summary, a web based application runs on a server. The server handles user requests, processes them, retrieves necessary files or data, and sends back responses that are displayed in the user’s browser. Servers play a crucial role in providing the necessary processing power, storage, security, and scalability required for web based applications to function effectively.
So the next time you use a web app, remember that it is running on a server behind the scenes. Understanding this concept can give you a deeper appreciation for the technology that powers the web apps we use every day.
