A An encryption method in which both a private key and a public key are used to encrypt and decrypt a message Asymmetric encryption (also called asymmetric-key encryption or public-key encryption) refers to an encryption method in which two keys are used to encrypt and decrypt a message: a private key and a public key. The public key is known to all sending and receiving parties involved in the communication, whether via Web browsers, email or instant messaging. The private key is used by the recipient to decrypt the message. Symmetric-key encryption uses the same key to encrypt and decrypt a message. In hash encryption, numbers generated by an algorithm from a text string are used to verify the integrity of transmitted messages.

Which protocol is used to receive email messages from an incoming mail server, and forces you to download email messages before reading, deleting or otherwise managing them? A Post Office Protocol (POP) B Network News Transfer Protocol (NNTP) C Internet Message Access Protocol (IMAP) D Simple Mail Transfer Protocol (SMTP)

A Post Office Protocol (POP) You receive mail from an incoming mail server using Post Office Protocol (POP) or Internet Message Access Protocol (IMAP). POP stores incoming email until users authenticate and download it. POP is the more accepted and widely used protocol for receiving and managing email. POP servers store and forward email messages to the host. For example, if you were to send an email message, the message would be stored in the appropriate mail server until the recipient downloaded it from the server. The POP server responds to a request, asks for a password, then forwards the messages immediately. IMAP handles messages in a more sophisticated manner than POP because it allows you to browse and manage email messages while they reside on the server. A POP server forces you to download email messages before reading, deleting or otherwise managing them. You send email to others with an outgoing server using Simple Mail Transfer Protocol (SMTP), which is responsible solely for sending—not receiving—email messages. A news server uses the Network News Transfer Protocol (NNTP) to host newsgroups.
