Web Hosting Interview Questions and Answers for 2 years experience

1. What is web hosting?

   • Answer: Web hosting is a service that provides individuals and organizations with a space on a server to store their website files and make them accessible via the internet. It involves providing server space, bandwidth, and other resources necessary for a website to function.

2. Explain different types of web hosting.

   • Answer: Common types include shared hosting (multiple websites on one server), VPS (virtual private server offering more resources and isolation), dedicated hosting (entire server dedicated to one website), and cloud hosting (distributed across multiple servers for scalability and reliability).

3. What is the difference between shared, VPS, and dedicated hosting?

   • Answer: Shared hosting is cost-effective but resource-limited, suitable for small websites. VPS offers more resources and isolation than shared, suitable for growing websites. Dedicated hosting provides maximum resources and control, ideal for large, high-traffic websites.
