    Which protocol is used to retrieve email from a mail server?

    • FTP

    • SMTP

    • IMAP

    • DNS

    Correct Answer
    A. IMAP
    Explanation
    IMAP is a protocol used by email clients to retrieve emails from a mail server. Unlike POP (Post Office Protocol), which downloads the email and usually removes it from the server, IMAP allows the email to remain on the server while providing access to it across multiple devices. This is particularly useful when users access their email from multiple locations, such as a phone, laptop, and desktop, because any actions performed on the email (such as reading, deleting, or moving) are synchronized across all devices. IMAP essentially keeps a copy of the email on the server, allowing for better flexibility in managing emails.

    Rate this question:

  • 25. 

    What is the base of a number system called?

    • Index

    • Subscript

    • Radix

    • None of the above

    Correct Answer
    A. Radix
    Explanation
    The correct answer is "Radix". In every number system, there is a base or radix which determines the number of unique digits used and the value of each digit. For example, in the decimal system, the radix is 10 because there are 10 unique digits (0-9). Similarly, in the binary system, the radix is 2 because there are only 2 unique digits (0 and 1). The radix is essential in understanding and interpreting numbers in different number systems.
