Question

To access the global internet, the following are required : (A) Electronic Mail Protocol (B) Order Protocol (C) File Transfer Protocol (D) Segment Protocol Choose the correct answer from the options given below:

• A. (A) and (B) only
• B. (A) and (C) only
• C. (B) and (D) only
• D. (B), (C) and (D) only

Hint:

Focus on the classic, foundational services of the internet: email, file transfer, and web browsing (HTTP, which isn't listed). Protocols like SMTP and FTP are key components. Unfamiliar terms like "Order Protocol" are likely distractors.

Answer 1

The Correct Option is B

Step 1: Understand what is required to "access the global internet". This implies using the core services and protocols that define the internet's functionality. The internet is a network of networks that functions using a suite of protocols, primarily TCP/IP.

Step 2: Evaluate the options. \[\begin{array}{rl} \bullet & \text{(A) Electronic Mail Protocol (e.g., SMTP, POP3): Email is a fundamental service of the internet, and its protocols are essential for its operation.} \\ \bullet & \text{(B) Order Protocol: This is not a standard internet protocol.} \\ \bullet & \text{(C) File Transfer Protocol (FTP): FTP is one of the original and core protocols of the internet, used for transferring files between computers.} \\ \bullet & \text{(D) Segment Protocol: This is not a standard internet protocol. The term "segment" is used in the context of the TCP protocol (TCP segment), but it's not a protocol itself.} \\ \end{array}\]

Step 3: Conclude. Electronic Mail Protocol and File Transfer Protocol are both real, fundamental protocols required for accessing key internet services.
