User's Manual for the Wireless Digital Media Player MP115
If this network is divided into 14 subnets, however, then the first 4 bits of the host address (0001) are
reserved for identifying the subnet.
The subnet mask is the network address plus the bits reserved for identifying the subnetwork. (By
convention, the bits for the network address are all set to 1, though it would also work if the bits were set
exactly as in the network address.) In this case, therefore, the subnet mask would be
11111111.11111111.11110000.00000000. It's called a mask because it can be used to identify the subnet to
which an IP address belongs by performing a bitwise AND operation on the mask and the IP address. The
result is the subnetwork address: Subnet Mask 255.255.240.000 11111111.11111111.11110000.00000000
IP Address 150.215.017.009 10010110.11010111.00010001.00001001
Subnet Address 150.215.016.000 10010110.11010111.00010000.00000000
The subnet address, therefore, is 150.215.016.000.
TCP/IP
The main internetworking protocols used in the Internet. The Internet Protocol (IP) used in conjunction with
the Transfer Control Protocol (TCP) form TCP/IP.
Universal Plug and Play
UPnP. A networking architecture that provides compatibility among networking technology. UPnP
compliant routers provide broadband users at home and small businesses with a seamless way to participate
in online games, videoconferencing and other peer-to-peer services.
UTP
Unshielded twisted pair is the cable used by 10BASE-T and 100BASE-Tx Ethernet networks.
WAN
A long distance link used to extend or connect remotely located local area networks. The Internet is a large
WAN.
WEB Proxy Server
A Web proxy server is a specialized HTTP server that allows clients access to the Internet from behind a
firewall.
The proxy server listens for requests from clients within the firewall and forwards these requests to remote
Internet servers outside the firewall. The proxy server reads responses from the external servers and then
sends them to internal client clients.
WEP
Wired Equivalent Privacy is a data encryption protocol for 802.11b wireless networks.
All wireless nodes and access points on the network are configured with a 64-bit or 128-bit Shared Key for
data encryption.
