IMAP is the protocol that IMAP clients use to communicate with the servers,
and SMTP is the protocol used to transport mail to an IMAP server.
The current version of the Internet Message Access Protocol is IMAP4. It is
similar to Post Office Protocol version 3 (POP3), but offers additional and more
complex features. For example, the IMAP4 protocol leaves your email messages
on the server rather than downloading them to your computer. If you wish to
remove your messages from the server, you must use your mail client to
generate local folders, copy messages to your local hard drive, and then delete
and expunge the messages from the server.
IP
IP is an acronym for Internet Protocol. It is a protocol used for communicating
data across a internet network.
IP is a "best effort" system, which means that no packet of information sent over
it is assured to reach its destination in the same condition it was sent. Each
device connected to a Local Area Network (LAN) or Wide Area Network (WAN)
is given an Internet Protocol address, and this IP address is used to identify the
device uniquely among all other devices connected to the extended network.
The current version of the Internet protocol is IPv4, which has 32-bits Internet
Protocol addresses allowing for in excess of four billion unique addresses. This
number is reduced drastically by the practice of webmasters taking addresses in
large blocks, the bulk of which remain unused. There is a rather substantial
movement to adopt a new version of the Internet Protocol, IPv6, which would
have 128-bits Internet Protocol addresses. This number can be represented
roughly by a three with thirty-nine zeroes after it. However, IPv4 is still the
protocol of choice for most of the Internet.
IPMC
IPMC is an acronym for IP MultiCast.
IP Source Guard
IP Source Guard is a secure feature used to restrict IP traffic on DHCP snooping
untrusted ports by filtering traffic based on the DHCP Snooping Table or
manually configured IP Source Bindings. It helps prevent IP spoofing attacks
when a host tries to spoof and use the IP address of another host.
L
LACP
LACP is an IEEE 802.3ad standard protocol. The Link Aggregation Control
Protocol, allows bundling several physical ports together to form a single logical
port.
