HTTPS is an acronym for Hypertext Transfer Protocol over Secure Socket Layer.
It is used to indicate a secure HTTP connection.
HTTPS provide authentication and encrypted communication and is widely used
on the World Wide Web for security-sensitive communication such as payment
transactions and corporate logons.
HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a
sublayer under its regular HTTP application layering. (HTTPS uses port 443
instead of HTTP port 80 in its interactions with the lower layer, TCP/IP.) SSL
uses a 40-bit key size for the RC4 stream encryption algorithm, which is
considered an adequate degree of encryption for commercial exchange.
I
ICMP
ICMP is an acronym for Internet Control Message Protocol. It is a protocol that
generated the error response, diagnostic or routing purposes. ICMP messages
generally contain information about routing difficulties or simple exchanges
such as time-stamp or echo transactions. For example, the PING command uses
ICMP to test an Internet connection.
IEEE 802.1X
IEEE 802.1X is an IEEE standard for port-based Network Access Control. It
provides authentication to devices attached to a LAN port, establishing a
point-to-point connection or preventing access from that port if authentication
fails. With 802.1X, access to all switch ports can be centrally controlled from a
server, which means that authorized users can use the same credentials for
authentication from any point within the network.
IGMP
IGMP is an acronym for Internet Group Management Protocol. It is a
communications protocol used to manage the membership of Internet Protocol
multicast groups. IGMP is used by IP hosts and adjacent multicast routers to
establish multicast group memberships. It is an integral part of the IP multicast
specification, like ICMP for unicast connections. IGMP can be used for online
video and gaming, and allows more efficient use of resources when supporting
these uses.
IGMP Querier
A router sends IGMP Query messages onto a particular link. This router is called
the Querier.
IMAP
IMAP is an acronym for Internet Message Access Protocol. It is a protocol for
email clients to retrieve email messages from a mail server.
