Networking
802.11b
: A wireless networking standard that supports data encryption and up to 11Mbps
bandwidth.
802.11g
: A wireless networking standard that supports data encryption and up to 54Mbps
bandwidth.
Ad-Hoc
: This wireless networking mode means that two PC’s are communicating in a
Peer-to-Peer network, without a router or an access point.
Bandwidth
: A measure of the rate at which data can be sent and received through the network.
This value is usually given in bits per second (bps) or Megabits per second (Mbps).
DHCP (Dynamic Host Configuration Protocol)
: A protocol that network devices use to obtain an
IP address, subnet mask, gateway, and DNS addresses automatically. A DHCP server can
be a router, ISP server, or PC running Internet Connection Sharing software. If you are using
a DHCP-capable device in your network, you will not need to assign a static IP address to
your DSM-520. However, if you do not have a DHCP-capable device in your network, you
will need to assign a static IP address to your DSM-520.
DNS (Domain Name System)
: A system used to translate computer names into IP addresses.
For example, a DNS server would translate www.dlink.com into 64.7.210.132
Ethernet
: The most commonly used wired network technology. Standard Ethernet supports
up to 10Mbps. Fast Ethernet supports up to 100Mbps.
Gateway
: This is the IP address of the device that connects you to another network such as a
router. A router would be the gateway between your local area network and the Internet.
Infrastructure
: This wireless networking mode is used by wireless networks with a router or
an access point.
IP Address (Internet Protocol Address)
: An IP address consists of four groups of digits separated
by periods. Each group of digits contain an 8-bit value as a number ranging from 0 to 255.
Each computer must have it’s own unique IP address. The IP addresses on your network
must be within the same range. For example, if one PC or device has an IP address of
192.168.0.2, the other devices should have IP addresses that are sequential, like 192.168.0.3
and 192.168.0.4.
ISP (Internet Service Provider)
: A commercial organization that provides subscribers with
access to the Internet.
Key
: Encryption keys allow you to easily change wireless encryption settings to maintain a
secure network. The DSM-520 supports 64-bit and 128-bit keys.
Netmask
: Commonly referred to as subnet mask, this is used to determine what subnet an
IP address belongs to.
RJ-45
: RJ-45 is the standard connector for Ethernet cabling. It looks like a phone cable
connector, but is slightly larger. RJ-45 connectors have 8 pins, 4 of which are used for
transmitting and receiving data.
