Does a numeric mailbox identifier have any advantage over a mnemonic identifier? Explain.

Several software systems permit the system administrator to select mailbox names, whereas other systems need a user s mailbox identifier through concatenating a user's first name, middle initial and last name, with underscore to separate the three items. For example, the email address for employee john Quiggley Public at expertsmind Corporation may be:

xxx_Q_Public@ expertsmind.com

On systems that need a user's login identifier to be utilized as a mailbox identifier, the resulting e-mail address is not nearly like readable. For illustration, if login accounts on a computer at nonexistent Corporation contain two six-digit numbers separated through a period, a single's e-mail address on which computer might be:

912743.253843@xxx .com

Evidently mnemonic from makes the mailbox portions of an e-mail address easier to keep in mind and enter correctly.
