Wireless Router user's manual IP IP Address ISP LAN MAC Address Metric MTU NAT IP (Internet Protocol) is the protocol in the TCP/IP communications protocol suite that contains a network address and allows messages to be routed to a different network or subnet. However, IP does not ensure delivery of a complete message-TCP provides the function of ensuring delivery. The IP (Internet Protocol) address refers to the address of a computer attached to a TCP/IP network. Every client and server station must have a unique IP address. Clients are assigned either a permanent address or have one dynamically assigned to them via DHCP. IP addresses are written as four sets of numbers separated by periods (for example, 211.23.181.189). An ISP is an organization providing Internet access service via modems, ISDN (Integrated Services Digital Network), and private lines. LANs (Local Area Networks) are networks that serve users within specific geographical areas, such as in a company building. LANs are comprised of servers, workstations, a network operating system, and communications links such as the router. A MAC address is a unique serial number burned into hardware adapters, giving the adapter a unique identification. A number that indicates how long a packet takes to get to its destination. MTU (Maximum Transmission/Transfer Unit) is the largest packet size that can be sent over a network. Messages larger than the MTU are divided into smaller packets. NAT (Network Address Translation - also known as IP masquerading) enables an organization to present itself to the Internet with one address. NAT converts the address of each LAN node into one IP address for the Internet (and vice versa). NAT also provides a certain amount of security by acting as a firewall by keeping individual IP addresses hidden from the WAN. (Network) Administrator NTP Packet Ping Port The network administrator is the person who manages the LAN within an organization. The administrator's job includes ensuring network security, keeping software, hardware, and firmware up-to-date, and keeping track of network activity. NTP (Network Time Protocol) is used to synchronize the realtime clock in a computer. Internet primary and secondary servers synchronize to Coordinated Universal Time (UTC). A packet is a portion of data that is transmitted in network communications. Packets are also sometimes called frames and datagrams. Packets contain not only data, but also the destination IP address. Ping (Packet INternet Groper) is a utility used to find out if a particular IP address is present online, and is usually used by networks for debugging. Ports are the communications pathways in and out of computers and network devices (routers and switches). Most PCs have serial and parallel ports, which are external sockets for connecting devices such as printers, modems, and mice. All network adapters use ports to connect to the LAN. Ports are typically numbered. - 56 -

IP
IP (Internet Protocol) is the protocol in the TCP/IP commu-
nications protocol suite that contains a network address and
allows messages to be routed to a different network or sub-
net. However, IP does not ensure delivery of a complete
message—TCP provides the function of ensuring delivery.
IP Address
The IP (Internet Protocol) address refers to the address of a
computer attached to a TCP/IP network. Every client and
server station must have a unique IP address. Clients are
assigned either a permanent address or have one dynami-
cally assigned to them via DHCP. IP addresses are written
as four sets of numbers separated by periods (for example,
211.23.181.189).
ISP
An ISP is an organization providing Internet access service
via modems, ISDN (Integrated Services Digital Network),
and private lines.
LAN
LANs (Local Area Networks) are networks that serve users
within specific geographical areas, such as in a company
building. LANs are comprised of servers, workstations, a
network operating system, and communications links such
as the router.
MAC Address
A MAC address is a unique serial number burned into
hardware adapters, giving the adapter a unique identifica-
tion.
Metric
A number that indicates how long a packet takes to get to its
destination.
MTU
MTU (Maximum Transmission/Transfer Unit) is the largest
packet size that can be sent over a network. Messages lar-
ger than the MTU are divided into smaller packets.
NAT
NAT (Network Address Translation - also known as IP mas-
querading) enables an organization to present itself to the
Internet with one address. NAT converts the address of
each LAN node into one IP address for the Internet (and
vice versa). NAT also provides a certain amount of security
by acting as a firewall by keeping individual IP addresses
hidden from the WAN.
(Network)
Administrator
The network administrator is the person who manages the
LAN within an organization. The administrator's job includes
ensuring network security, keeping software, hardware, and
firmware up-to-date, and keeping track of network activity.
NTP
NTP (Network Time Protocol) is used to synchronize the
realtime clock in a computer. Internet primary and secon-
dary servers synchronize to Coordinated Universal Time
(UTC).
Packet
A packet is a portion of data that is transmitted in network
communications. Packets are also sometimes called frames
and datagrams. Packets contain not only data, but also the
destination IP address.
Ping
Ping (Packet INternet Groper) is a utility used to find out if a
particular IP address is present online, and is usually used
by networks for debugging.
Port
Ports are the communications pathways in and out of com-
puters and network devices (routers and switches). Most
PCs have serial and parallel ports, which are external sock-
ets for connecting devices such as printers, modems, and
mice. All network adapters use ports to connect to the LAN.
Ports are typically numbered.
