Intranet
A network based on TCP/IP Protocol
belonging to an organization, and accessible
only by that organization’s members,
employees, or others with authorization.
IP Address
An identifier for a computer or device on a
TCP/IP network. Networks using the TCP/IP
Protocol route messages based on the IP
Address of the destination. The format of an
IP address is a 32-bit numeric address written
as four numbers separated by periods. Each
number can be from zero to 255.
IPSec
Internet Protocol Security is a security
standard for network transmission, which is
often used for VPN connections. It provides
authentication and packet encryption over the
Internet.
ISP
Short for Internet Service Provider, a
company that provides access to the Internet
for a fee.
Local Area Network (LAN)
A computer network that spans a relatively
small area. Most LANs are confined to a
single building or group of buildings.
However, one LAN can be connected to other
LANs over any distance. A system of LANs
connected in this way is called a wide area
network (WAN)
MAC Address
Short for Media Access Control Address, a
hardware address that uniquely identifies each
node of a network.
NAT
Short for Network Address Translation, a
routing protocol that allows global IP
Addresses to be translated into multiple
private IP Addresses for use on internal LAN
networks. The explosion in the use of the
Internet has created a critical problem for the
Internet Assigned Numbers Authority
(IANA) which is in charge of assigning IP
Addresses to Internet users, ISPs etc. NAT is
a technology that has been introduced to help
maximize the utilization of assigned IANA
and global IP Addresses.
Network Protocol
Network protocols encapsulate and forward
data packets from one interface to another.
PAP/CHAP
Short for Password Authentication Protocol
and Challenge Handshake Authentication
Protocol. Most ISPs use either one for user
identification. If your ISP doesn’t support
these two protocols, contact them for an
authentication script.
PPP
Short for Point-to-Point Protocol, a
communications protocol for transmitting
information over standard telephone lines
between devices from different manufacturers.
PPPoE
Short for PPP over Ethernet, relying on two
widely accepted standards, Ethernet and the
Point-to-Point Protocol. PPPoE is a
communications protocol for transmitting
information over the Ethernet between
devices from different manufacturers.
PPTP
The acronym of Point to Point Tunnelling
Protocol, PPTP encapsulates the packet for
transmission over the Internet. It creates a
private “tunnel” through the large public
network to have similar security of private
network without actually leasing a private
line. PPTP is normally used for VPN
connections.
Protocol
An agreed format for transmitting, sending and
receiving data between two devices.
