ViewSonic Wireless Media Gateway 95
WLAN must use the same SSID. A device will not be permitted to
join the BSS unless it can provide the unique SSID. Because an
SSID can be sniffed in plain text from a packet, it does not supply
any security to the network. An SSID is also referred to as a
Network Name because essentially it is a name that identifies a
wireless network.
SSL (Secure Sockets Layer). Commonly used encryption scheme
used by many online retail and banking sites to protect the financial
integrity of transactions. When an SSL session begins, the server
sends its public key to the browser. The browser then sends a
randomly generated secret key back to the server in order to have
a secret key exchange for that session.
Subnetwork or Subnet. Found in larger networks, these smaller
networks are used to simplify addressing between numerous
computers. Subnets connect to the central network through a
Gateway, hub or gateway. Each individual wireless LAN will
probably use the same subnet for all the local computers it talks to.
Switch. A type of hub that efficiently controls the way multiple
devices use the same network so that each can operate at optimal
performance. A switch acts as a networks traffic cop: rather than
transmitting all the packets it receives to all ports as a hub does, a
switch transmits packets to only the receiving port.
TCP (Transmission Control Protocol). A protocol used along with
the Internet Protocol (IP) to send data in the form of individual units
(called packets) between computers over the Internet. While IP
