Access Point
An access point is a device that
controls encryption on the
network and may bridge or route
wireless traffic to a wired Ethernet
network or the Internet. Access
points that act as routers can also
assign IP addresses to your PC
using DHCP services.
Ad Hoc Mode
Two or more wireless Ethernet
computers (802.11b/g) may
communicate with each other
without a wireless access point.The
wireless cards must be set to ad
hoc mode instead of infrastructure
mode. Also referred to as a peer-to-
peer network.
Auto-IP
The networked device obtains an
IP address for itself.
CODEC
COder/DECoder: A codec software
for converting audio or video to a
specific format. It can also decode
media encoded in this format.
Popular codecs include: MPEG-1,
MPEG-2, MPEG-4, Indeo, etc. AVI is
not a codec but a format that can
be encoded using different codecs.
DHCP
The Dynamic Host Configuration
Protocol (DHCP) can be used to
automatically assign IP addresses
and to provide other configuration
information for networked
devices. DHCP enables devices
on an IP network to extract their
configurations from a server
(the "DHCP server") or servers,
in particular servers that have
no exact information.The most
significant piece of information
distributed in this manner is the IP
address.
DVR-MS
Microsoft introduced the *.dvr-
ms file format in Windows XP .
Similar to *.asf, *.dvr-ms allows the
creation of key PVR functionality,
including time-shifting, live pause,
and simultaneous record and
playback.
FOURCC
Four character code identifying the
video data stream format.
Gateway
A gateway is the point at which
one network connects to another
network. A gateway can be
composed of software, hardware,
or a combination of the two.
Infrastructure Mode
Wireless Ethernet adapters
default to infrastructure mode, a
communication method requiring
a wireless access point.
IP Address
During the process of establishing
communication, devices acquire
addresses known as IP addresses.
These addresses are used to
direct network traffic to the
proper destination. An IP address
is typically displayed in "dotted
decimal" format (e.g., 192.168.0.2).
LAN
Local area network.
Network
A network is the mechanism by
which devices communicate with
each other. With GoVideo D5
Streaming Media, these devices
include your DVD Player and your
computer(s).
Peer-to-peer network
A peer-to-peer network within the
realm of GoVideo D5 Streaming
Media is defined as two or more
wireless Ethernet computers
(802.11b/g) that communicate
with each other without a wireless
access point. Also referred to as ad
hoc.
Router
A router is a gateway device that
determines the route of data
packets as they travel from one
network to another network(s). A
router can be either a hardware
device or a software application.
SSID
The SSID (Service Set Identifier)
allows a WLAN to be split into
multiple networks, each with
a uniqe identifier, which is
programmed into one or more
access points.To access any of
the networks, a client computer
must be configured with the
corresponding SSID identifier for
that network.The SSID acts as
a simple password providing a
measure of security. A weakness is
that the SSID is widely known and
shared.
Static IP
Static IP addresses are numeric
addresses that you assign to
uniquely identify your network
devices. Important: Only
experienced network users should
be assigning static IP addresses.
Subnet
A subnet is a portion of a network
that shares a common address
component. On TCP/IP networks,
subnets are defined as all devices
whose IP addresses have the same
prefix. For example, all devices
with IP addresses that start with
100.100.100 would be part of the
same subnet. Dividing a network
into subnets is useful for both
security and performance reasons.
System Tray
The system tray (also known
as "systray") is a section of the
taskbars in the Microsoft®
Windows® desktop user interface
used to display the clock and the
icons of certain programs so that a
user is continually reminded that
they are there and can easily click
one of them.
Transcoding
Transcoding is the process of
converting a media file or object
from one format to another.
WEP
WEP (Wired Equivalent Privacy) is a
security protocol for wireless local
area networks (WLANs) defined
in the 802.11b/g standard. WEP is
designed to provide the same level
of security as that of a wired LAN.
Wired LANs are inherently more
secure being somewhat protected
from unauthorized access by their
physical structure. WLANs, which
are over radio waves do not have
the same physical structure, and
consequently, are more vulnerable
to tampering. WEP provides
security by encrypting the data
so that it is protected as it is
transmitted.To minimize the risk of
radio frequency (RF) interception,
WEP is specified for encryption and
authentication between clients
and access points according to the
802.11 standard. All clients and
access points must be configured
with the same key for encrypting
and decrypting data transmissions.
WEP keys are 64 or 128 bits in
length.
Wired Ethernet Network
A wired Ethernet network is a
network in which the devices
communicate with each other
using physical cables (using the
Ethernet 802.3 standard).
WLAN
Wireless local area network using
radio waves.
