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 via telephone lines and radio waves. 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 ISP
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 your ISP 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. It’s a communications protocol for transmitting information
over the Ethernet between devices from different manufacturers.
PPTP
The acronym of Point to Point Tunneling Protocol, PPTP encapsulates the packet for transmission over the internet. It creates a private "tunnel" over the large public
network which has almost equal security to a provate network without actually having to lease a private line.
Protocol
An agreed format for transmitting, sending and receiving data between two devices.
Router
An internet device that routes requests for information to other routers until the information’s location is found and the data can be transmitted back to the origin of the
request.
TCP/IP
Short for Transmission Control Protocol and Internet Protocol, the suite of communications protocols that enable hosts on the internet to connect and exchange streams of
data.
VPN
The acronym of Virtual Private Network. Via access control and encryption, VPN brings the security to the data transmission through the internet as it is transmitted through
a private network. It not only takes advantage of the economies of scale but also gets the high level security while the packet is sent over the large public
network.
Wide Area Network (WAN)
A system of LANs being connected by telephone lines and radio waves. Although some WANs may be privately owned, they are usually considered a means of public access.
