Access Point
An Access Point (AP) is a hardware device or a computer's software that
acts as a communication hub for users of a wireless device to connect to a
wireless LAN (WLAN). The HN294dp has an integrated WLAN access point
which complies to the 802.11b standard.
ADSL
Short for Asymmetric Digital Subscriber Line. A variation of the DSL
technologies that is most familiar to home and small business users. ADSL
is called "asymmetric" because most of its two-way or duplex bandwidth is
devoted to the downstream direction, sending data to the user. Only a small
portion of bandwidth is available for upstream or user-interaction
messages.
ARP
Short for Address Resolution Protocol, a TCP/IP protocol used to convert
an IP address into a physical address, such as an Ethernet address. A host
wishing to obtain a physical address broadcasts an ARP request onto the
TCP/IP network. The host on the network that has the IP address in the
request then replies with its physical hardware address. There is also
Reverse ARP (RARP) which can be used by a host to discover its IP
address. In this case, the host broadcasts its physical address and a RARP
server replies with the host's IP address.
Asynchronous
Occuring at different times. For example, electronic mail is asynchronous
communication because it does not require the sender and receiver to be
connected at the same time.
ATM
Short for Asynchronous Transfer Mode, a network technology based on
transferring data in cells or packets of a fixed size. The cell used with ATM
is relatively small compared to units used with older technologies. The
small, constant cell size allows ATM equipment to transmit video, audio,
and computer data over the same network, and assure that no single type
of data hogs the line.
