Gateway
A gateway is a network point that acts as an entrance to another network. In a
network for an enterprise, a computer server acts as a gateway node, and also a
proxy server and a firewall server.
IP address
An IP address is a 32-bit number that identifies each sender or receiver of
information that is sent in packets across the Internet. An IP address has two parts:
the identifier of a particular network on the Internet and an identifier of the particular
device (which can be a server or a workstation) within that network.
Internet Protocol
The Internet Protocol (IP) is the method or protocol by which data is sent from one
computer to another on the Internet. When you send or receive data (for example, an
e-mail note or a Web page), the message gets divided into little chunks called
packets. Each of these packets contains both the sender's Internet address and the
receiver's address. The Internet Protocol just delivers them.
IMAP
IMAP (Internet Message Access Protocol) is a standard protocol for accessing e-mail
from your local server. IMAP requires continual access to the server during the time
that you are working with your mail. IMAP provides the user more capabilities for
retaining e-mail on the server and for organizing it in folders on the server. IMAP can
be thought of as a remote file server.
MAC address
In a local area network (LAN) or other network, the MAC (Media Access Control)
address is your computer's unique hardware number. (On an Ethernet LAN, it's the
same as your Ethernet address.)
LAN
A local area network (LAN) is a group of computers and associated devices that
share a common communications line or wireless link and typically share the
resources of a single processor or server within a small geographic area (for example,
within an office building).
JPEG
JPEG (pronounced "jay-peg) is a format that is commonly used for color images
displayed on the Internet. JPEG reduces the file size of an image by discarding some
of the non-critical data of the image. JPEG retains all of the color information of an
image and offers varying degrees of compression.
