1. What is the difference between a thread and a process in a multitasking operating system?

In a multitasking operating system:

  • Process: Represents a program in execution, including its own memory space and resources.
  • Thread: Represents a single sequence of execution within a process, sharing the same memory space.

2. How does garbage collection work in programming languages like Java or C#?

Garbage collection automatically manages memory by reclaiming memory occupied by objects that are no longer in use. It does this by periodically identifying and deleting objects that are no longer reachable.

  6. Rollback Plan: Have a rollback plan in case of unexpected issues.

90. What is the purpose of a reverse proxy in a web application architecture?

A reverse proxy sits in front of web servers and directs client requests to the appropriate server. It provides benefits like:

  • Load Distribution: Distributes client requests among multiple servers.
  • Caching: Stores copies of frequently accessed resources for faster retrieval.
  • Security: Acts as a barrier, protecting servers from direct access.

91. How do you handle session management in a stateless environment like RESTful APIs?

In a stateless environment, I use token-based authentication. Upon successful login, the server generates a unique token and sends it to the client. This token is included in subsequent requests to authenticate the user.


92. Explain the concept of Continuous Integration (CI) and Continuous Deployment (CD).

  • Continuous Integration (CI): Developers integrate code changes into a shared repository multiple times a day. Automated tests are run to validate the changes. This ensures early detection of integration issues.
  • Continuous Deployment (CD): After successful CI, the code is automatically deployed to production or staging environments. This streamlines the release process and minimizes manual intervention.

93. What is the purpose of a Content Delivery Network (CDN) in web applications?

A CDN is a network of geographically distributed servers that work together to deliver content efficiently. It caches static content like images, CSS, and JavaScript, reducing server load and improving website performance for users worldwide.


94. How do you ensure data privacy and compliance with regulations like GDPR in a web application?

I ensure data privacy and compliance through the following measures:

  • Data Encryption: Use HTTPS and SSL/TLS protocols to encrypt data in transit.

  • Data Minimization: Only collect and store necessary user data.
  • User Consent: Obtain clear consent for data collection and processing.
  • Data Deletion: Provide mechanisms for users to request data deletion.

95. What is a microservices architecture, and what are its benefits?

A microservices architecture is an approach to building software systems as a collection of small, independent services. Each service runs in its own process and communicates with other services via APIs. Benefits include:

  • Scalability: Each service can be scaled independently.
  • Flexibility: Different services can be built with different technologies.
  • Maintainability: Easier to maintain and update individual services.
  • Isolation: Failures in one service don’t necessarily affect others.

Common vulnerabilities include SQL injection, Cross-Site Scripting (XSS), Cross-Site Request Forgery (CSRF), and improper authentication. To mitigate:

  • Input Validation: Validate and sanitize user inputs to prevent SQL injection and XSS attacks.
  • CSRF Tokens: Use tokens to validate requests, preventing CSRF attacks.
  • Strong Password Policies: Enforce strong password policies and employ techniques like bcrypt for secure password storage.

98. What is the purpose of a container orchestration platform like Kubernetes?

Kubernetes automates the deployment, scaling, and management of containerized applications. It provides features like:

  • Scaling: Automatic scaling based on resource usage or custom metrics.
