16. What is the purpose of the StringBuilder class in C#?
The StringBuilder class is used to efficiently manipulate strings. Unlike the string class, which is immutable, StringBuilder allows you to modify a string in place without creating a new object each time.

17. What is the difference between synchronous and asynchronous programming in .NET Core?
Synchronous programming blocks the current thread until a task is completed, whereas asynchronous programming allows the current thread to continue executing while the task is completed on a separate thread. Asynchronous programming can improve performance by allowing the application to make more efficient use of system resources.

Information Security Do’s and Don’ts for ChatGPT:
ChatGPT (Chat Generative Pre-Trained Transformer) is an AI chatbot developed by OpenAI.
It is built on top of Open AI’s GPT-3.5 family of large language models and has been fine-tuned using both supervised and reinforcement learning techniques. It can create compelling texts that are hard to distinguish from those written by humans, among other uses.

What are the Limitations?
Although ChatGPT is a powerful AI-based chatbot system, it does have some limitations. It can only provide answers based on the data it has been trained on. Also, since it uses the information learnt from training data to generate responses, there is always room for error—so all output should be fact-checked for accuracy and timelines. The Chabot may not be able to provide in-depth information or understand context or nuances in conversation as well. As with all AI tools, all business leaders should be aware of the dangers of potential bias. If the data ChatGPT is trained on is biased, the answers the bot provides will be biased, as well. Hence, we need to be vigilant about monitoring output from the chatbot to ensure it is free of bias and offensive content.

web.config file :
This web.config file in a xml file means than web.config file extension in .xml, we need not restart the web server, when the settings change in the configuration file, asp.net automatically detect the changes in the configuration file. In this configuration many type of settings store in this file.

For example

1-Database connection
2-Cache settings
3-Cookie setting
4-Session settings
5-Error handling
6-Security

Difference between session and cookies

1-The main difference between both of them is that sessions are saved on the server-side, whereas cookies are saved on the user's browser or client-side.
2-A session stores the variable and their value on server but in cookies are store client machine
3-Session ends when user logout the website or close his browser but cookies is set for life time
4-Session can store unlimited data but cookies store limited data
5-In session maximum memory limit is 128 MB but in cookie 4kb memory limit
