Glossary
AAC
Abbreviation for Advanced Audio
Coding. It is a standard for audio file
compression determined by the
MPEG (Motion Picture Experts
Group), an ISO (International
Organization for Standardization)/
IEC (International Electrotechnical
Commission) working group.
DHCP
Abbreviation for Dynamic Host
Configuration Protocol. A system for
automatically allocating
configuration data required for an
Internet connection.
DLNA
Abbreviation for Digital Living
Network Alliance. The DLNA is a
nonprofit organization that
establishes design guidelines for
digital content shared over networks.

DNS
Abbreviation for Domain Name
System. A server that translates
domain names to IP addresses, or IP
addresses to domain names. A DNS
is identified by an IP address. Also
called a “DNS server.”
IP address
IP addresses usually comprise four
groups of up to three digits each,
separated by a period (such as
192.168.239.1). All devices on a
network must have an IP address.
LAN
Abbreviation for Local Area
Network.
LAN is a general name for networks
set up for communication among
devices including computers,
printers, and fax machines in
relatively small areas such as offices
or buildings.
MAC address
Abbreviation for Media Access
Control address. It is an
identification name assigned to all
network devices. Each device has its
own address and there are no
duplicate addresses. A MAC address
may be necessary when identifying
the unit separately from other
devices (such as a DLNA server).
Network key (security key)
An encryption key used to limit the
devices with which communication
can occur. It is used to provide
higher security for devices
communicating via a wireless LAN
router/access point.
Proxy
A program or a server that provides
Internet access to computers within a
firewall or quicker downloading of
web pages.
Router
A device that bridges networks,
converting the protocols and
addresses of each network. When
connecting multiple network devices
to the Internet, a router is necessary.
The term “router” by itself may refer
to any of these devices.
SSID
Abbreviation for Service Set
IDentifier. It is a name that identifies
a particular access point within an
IEEE 802.11 wireless LAN. To
connect with an access point, a client
device must be set with the same
SSID. SSIDs can be up to 32
characters long. For higher security,
a network key is normally also used.
In this case, connection cannot occur
unless the SSID matches the network
key.
WEP
Abbreviation for Wired Equivalent
Privacy. An encryption key used in
wireless LAN networks. As an IEEE
standard based on RC4 algorithm
cryptography, WEP is used to secure
IEEE 802.11b wireless networks.
During the transmission of a
message between a wireless LAN
access point and a client device, the
sending side encrypts the data and
the receiving side decrypts it. For
communication to occur, both
devices must use a common code
key, which is called the “WEP key.”
The encryption level is indicated by
the bit count of the key; e.g., 64 bits
or 128 bits. The higher the bit count,
the higher the security level.
WMA
Abbreviation for Windows Media
Audio. WMA is audio compression
technology developed by Microsoft
Corporation that allows audio files to
be compressed to about 1/22 of the
data size of a standard compact disc.
WPA
Abbreviation for Wi-Fi Protected
Access. An encryption standard for
wireless LAN networks created by
the Wi-Fi Alliance to remedy a
number of serious security problems
in the WEP system. In addition to the
network name (SSID) and
encryption key (WEP), this protocol
uses a user authentication framework
called “EAP” (Extensible
Authentication Protocol) and a
protocol called “TKIP” (Temporal
Key Integrity Protocol) which
automatically updates the encryption
code at regular intervals for higher
security.
