what is Usability in UX UI?
Usability focuses on how easily users can interact with and navigate through a product. A usable design is intuitive, efficient, and error-tolerant.
200
what is Regression testing?
Ensuring that new code changes don't negatively impact existing functionalities. It involves re-running previous test cases to catch any unintended side effects.

Explain Request and Response Validation: in postman
QA professionals use Postman to set up assertions and validations for API responses. This ensures that the API behaves as expected and meets the defined requirements.
400
What does NAT stand for and what is this protocol used for?
Network Address Translation, provides a way for multiple computers on the same network to share a single connection to the internet.

What is the difference between internet, intranet, and extranet?
Internet: applications are accessed by anyone from any location using the web.
Intranet: Limited access to users in the same organization
Extranet: external users are allowed or provided with access to use the network application of the organization
400
what is color theory in UI?
Colors evoke emotions and convey meaning. Understanding color theory helps designers choose a color palette that aligns with the brand and creates a positive user experience.

explain Mock Servers in postman
Postman allows the creation of mock servers, enabling QA teams to simulate API responses before the actual implementation is available. This is useful for parallel development and testing.
500
What is are subnets in a VPC in aws
In the context of networking and cloud computing, a Virtual Private Cloud (VPC) is a virtual network dedicated to your AWS account. Subnets within a VPC are divisions of IP address ranges used to organize and segment the IP space within the VPC. They play a crucial role in managing and securing network traffic within the VPC.

What is the similarity and difference between encryption and hashing?
Both convert data into an unreadable format.
Encryption: data can be converted back to original form.
Hashing: data cannot be converted back
500
What is the purpose of data encapsulation?
To enable data transmission from one computer to another.
It basically takes data from one protocol and translates it into another protocol so that the data can continue to move across the network.
500
what are microinteractions?
Microinteractions are subtle animations or visual cues that provide feedback, guide users, and enhance the overall user experience.
