Consider the following 2 statements given below:Statement 1: Each object in persistent HTTP suffers a delay of 2 RTTs: one RTT for establishing the TCP connection and one RTT to request and receive the object.Statement 2: HTTP is a stateless protocol.Which of the following statement is true or false?a)Statement 1 is true only.b)Statement 2 is true only.c)Statement 1 is false.d)Statement 2 is false.Correct answer is option 'B,C'. Can you explain this answer?

Question

Answer

Statement 1: Each object in persistent HTTP suffers a delay of 2 RTT one RTT for establishing the TCP connection and one RTT to request and receive the object.

This Statement is not true. Since Non-persistent HTTP causes a delay of 2 RTT in TCP transmission.

Persistent HTTP can send data and Objects both in a single TCP connection only so no new TCP connection is required.

Statement 2: HTTP is a stateless protocol.

This Statement is true. Since HTTP does not maintain user state information in its server.

Hence, the correct options are (B) and (C).

Answer

Statement 1: Each object in persistent HTTP suffers a delay of 2 RTTs: one RTT for establishing the TCP connection and one RTT to request and receive the object.
This statement is true.

Explanation:
When using persistent HTTP, the TCP connection between the client and the server is kept open after the initial request. This allows multiple objects to be requested over the same connection without the need to establish a new TCP connection for each object. However, each object still suffers a delay of 2 round-trip times (RTTs).

Reasoning:
- One RTT is required to establish the TCP connection. This includes the time taken for the client to send a SYN packet to the server, the server to respond with a SYN-ACK packet, and the client to acknowledge the SYN-ACK packet with an ACK packet. This process typically takes one RTT.
- Another RTT is required to request and receive the object. After the TCP connection is established, the client sends an HTTP request to the server, and the server responds with the requested object. This request and response process typically takes one RTT.

Therefore, each object in persistent HTTP suffers a delay of 2 RTTs.

Statement 2: HTTP is a stateless protocol.
This statement is true.

Explanation:
HTTP (Hypertext Transfer Protocol) is a protocol used for transmitting hypertext (HTML) documents over the internet. It is a stateless protocol, meaning that it does not retain any information about previous requests or responses.

Reasoning:
- Stateless nature: When a client sends an HTTP request to a server, the server processes the request and sends back a response. Once the response is sent, the server does not retain any information about the client or the previous requests made by the client. Each request is treated independently.
- No session information: Unlike stateful protocols such as FTP or Telnet, HTTP does not maintain any session information. Each request is self-contained and does not rely on previous requests or responses.
- Cookies for session management: To maintain state and session information, HTTP uses cookies. Cookies are small pieces of data stored on the client's browser, which are sent back to the server with each subsequent request. By using cookies, websites can maintain user-specific information and provide personalized experiences.

Therefore, HTTP is indeed a stateless protocol.

Conclusion:
Based on the explanations above, the correct answer is option B and C. Statement 1 is true because each object in persistent HTTP suffers a delay of 2 RTTs. Statement 2 is also true because HTTP is a stateless protocol.
