GLOSSARY 107 MAC Media Access Control. A protocol specified by the IEEE for determining which devices have access to a network at any one time. MAC Address Media Access Control Address. Also called the hardware or physical address. A layer 2 address associated with a particular network device. Most devices that connect to a LAN have a MAC address assigned to them as they are used to identify other devices in a network. MAC addresses are 6 bytes long. NAT Network Address Translation. NAT enables all the computers on your network to share one IP address. The NAT capability of the Router allows you to access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP. NAT-T Network A Network is a collection of computers and other computer equipment that are connected for the purpose of exchanging information or sharing resources. Networks vary in size, some are within a single room, others span continents. Network Interface Card (NIC) A circuit board installed into a piece of computing equipment, for example, a computer, that enables you to connect it to the network. A NIC is also known as an adapter or adapter card. Protocol A set of rules for communication between devices on a network. The rules dictate format, timing, sequencing and error control. PPPoE Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of data transmission originally created for dial-up connections; PPPoE is for Ethernet connections. PPTP Point-to-Point Tunneling Protocol is a method of secure data transmission between two remote sites over the internet. RJ-45 A standard connector used to connect Ethernet networks. The "RJ" stands for "registered jack".

MAC
Media Access Control. A protocol specified by the IEEE for determining
which devices have access to a network at any one time.
MAC Address
Media Access Control Address.
Also called the hardware or physical
address. A layer 2 address associated with a particular network device.
Most devices that connect to a LAN have a MAC address assigned to
them as they are used to identify other devices in a network. MAC
addresses are 6 bytes long.
NAT
Network Address Translation. NAT enables all the computers on your
network to share one IP address. The NAT capability of the Router allows
you to access the Internet from any computer on your home network
without having to purchase more IP addresses from your ISP.
NAT-T
Network
A Network is a collection of computers and other computer equipment
that are connected for the purpose of exchanging information or sharing
resources. Networks vary in size, some are within a single room, others
span continents.
Network Interface
Card (NIC)
A circuit board installed into a piece of computing equipment, for
example, a computer, that enables you to connect it to the network. A
NIC is also known as an adapter or adapter card.
Protocol
A set of rules for communication between devices on a network. The
rules dictate format, timing, sequencing and error control.
PPPoE
Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method
of data transmission originally created for dial-up connections; PPPoE is
for Ethernet connections.
PPTP
Point-to-Point Tunneling Protocol is a method of secure data transmission
between two remote sites over the internet.
RJ-45
A standard connector used to connect Ethernet networks. The “RJ”
stands for “registered jack”.
