Top 10 Questions for Client Server Programmer Interview

1. Explain the difference between TCP and UDP protocols?

• TCP (Transmission Control Protocol) is a reliable, connection-oriented protocol.
• It guarantees delivery of data in the correct order and with error checking.
• UDP (User Datagram Protocol) is an unreliable, connectionless protocol.
• It does not guarantee delivery of data and is best suited for applications where speed is more important than reliability.

2. How does a client-server architecture work?

• A client sends a request to a server.
• The server processes the request and sends a response back to the client.
• The client and server communicate over a network connection.

3. Explain the role of a socket in client-server programming?

• A socket is an endpoint of a bidirectional communication channel.
• It is used to send and receive data between two processes.

4. What are the advantages of using a multi-tier architecture?

• Modularity: The application is divided into separate tiers, which can be developed and maintained independently.
• Scalability: The application can be easily scaled by adding or removing tiers.
• Security: The application can be made more secure by isolating the different tiers.

5. What are the challenges of developing a client-server application?

• Network latency: The time it takes for data to travel between the client and server can be a challenge.
• Security: Client-server applications are vulnerable to a variety of security threats, such as hacking.
• Scalability: Client-server applications can be difficult to scale to handle a large number of users.

6. What is the difference between a synchronous and asynchronous client-server architecture?

• In a synchronous architecture, the client waits for the server to respond before continuing.
• In an asynchronous architecture, the client does not wait for the server to respond before continuing.

7. What are the advantages of using a RESTful API?

• Simplicity: RESTful APIs are easy to design and implement.
• Scalability: RESTful APIs can be easily scaled to handle a large number of requests.
• Flexibility: RESTful APIs can be used to build a wide variety of applications.

8. What are the different types of databases that can be used in a client-server application?

• Relational databases
• NoSQL databases
• In-memory databases

9. What are the different types of caching mechanisms that can be used in a client-server application?

• Client-side caching: Caching data on the client side can reduce the number of requests to the server.
• Server-side caching: Caching data on the server side can reduce the load on the database.

10. What are the best practices for designing a scalable client-server architecture?

• Use a multi-tier architecture.
• Use a stateless protocol.
• Use caching.
• Load balance the server tier.
