Explanation:
Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive emails from a
remote server to a local email client. POP3 allows you to download email messages on your local
computer and read them even when you are offline.
The Internet Message Access Protocol (IMAP) is a mail protocol used for accessing email on a
remote web server from a local client. IMAP and POP3 are the two most commonly used Internet
mail protocols for retrieving emails. Both protocols are supported by all modern email clients andweb servers.
Main difference between IMAP and POP3:
The POP3 protocol assumes that there is only one client connected to the mailbox. In contrast, the
IMAP protocol allows simultaneous access by multiple clients. IMAP is suitable for you if your
mailbox is about to be managed by multiple users.
Simple Mail Transfer Protocol (SMTP) is the standard protocol for sending emails across the
Internet. SMTP uses TCP port 25.

Switches

Answer: C
Explanation:
A switch filters and forwards traffic that is based on certain criteria. A bridge and a router is both
an example of a switch. A switch is able to manage multiple, simultaneous pairs of connections
between communicating systems. Switches can in many cases be used as a network concentrator
that will split flat network segments into dedicated communication links. Switches are able to split
collision domains but can also provide a greater aggregate bandwidth between groups of
communicating devices. Switches can also improve the overall performance.
Incorrect Answers:
A: A Router is a network device that can interconnect two or more network
segments.References:David Groth and Toby Skandier, Network+ Study Guide (4th Edition),
Sybex, Alameda CA, 2005, pp 32-33
B: A gateway is able to operate on all levels of the OSI model. It will interface between different
types of networks or protocols. It also executes conversions between the numbers of protocols at
the application layer.
D: A bridge will connect two networks. It will also pass traffic between them base only on the node
address. You can thus say that the main function of a bridge is to keep the traffic separated on
both sides of the bridge. Bridges operate on the Data Link Layer of the OSI model.
