Roaming
The ability for a wireless device moving from one access point’s range to another without
losing the connection.
Router
An Internet device that routes requests for information to other routers until the information’s
location is found and the data can be transmitted back to the origin of the request.
SPI
SPI is an acronym for Stateful Packet Inspection. The SPI engine examines not just the headers
of the packet, but also the packet contents, it can then determine more about the packet than just
its source and destination information. Moreover, stateful inspection firewalls also close off
ports until a connection to the specific port is requested.
TCP/IP
Short for Transmission Control Protocol and Internet Protocol, the suite of communications
protocols that enable hosts on the Internet to connect and exchange streams of data.
VPN
VPN is an acronym for Virtual Private Network. Via access control and encryption, VPN brings
the same security to data transmission through the Internet as if it being transmitted through a
private network. It not only takes advantage of economies of scale but also ensures high level
security while the packet is sent over the large public network.
Wide Area Network (WAN)
A system of LANs being connected by telephone lines and radio waves. Although some WANs
may be privately owned, they are usually considered a means of public access.
WEP
An acronym for Wired Equivalent Privacy. It is an encryption mechanism used to protect
your wireless data communications. WEP uses a combination of 64-bit/128-bit keys to encrypt
data that is transmitted between all points in a wireless network to insure data security. It is
described in the IEEE 802.11 standard.
