Question

is the widely used service of the through which users can send and receive messages in an efficient way.

Choose the correct answer to fill in the blanks.

1. A. Storage device, computer
2. B. Input device, super computer
3. C. E-mail, Internet (Correct answer)
4. D. None of the above

Correct Answer

Option C — E-mail, Internet

Detailed Solution & Explanation

The correct answer is E-mail, Internet.

Key Points

• E-mail (electronic mail) is the widely used service, and the Internet is the network through which it operates.
• The sentence structure requires a *service* in the first blank and a *network* in the second; only this pair satisfies both.
• Storage device and input device are hardware components, not services, and neither a computer nor a supercomputer is the medium over which messages travel.

Additional Information

• E-mail relies on protocols such as SMTP for sending, and POP3 or IMAP for retrieving messages.
• The first electronic mail message was sent by Ray Tomlinson in 1971, who also chose the @ symbol to separate the user name from the host.
