Firewall A security system that helps protect a network from external threats,
such as hacker attacks, originating outside the network. A hardware Firewall is a
connection routing device that has specific data checking settings and that helps
protect all of the devices connected to it.
Firmware Software information stored in nonvolatile memory on a device.
FTP Acronym for `File Transfer Protocol'. The standard Internet protocol for down-
loading, or transferring, files from one computer to another.
Gateway address The IP address you use when you make a connection outside
your immediate network.
Gateway A device that acts as a central point for networked devices, receives
transmitted messages, and forwards them. Watson can link many computers on a
single network, and can share an encrypted Internet connection with wired and
wireless devices.
Hexadecimal A numbering system that uses 16 rather than 10 as the base
for representing numbers. It is therefore referred to as a base-16 numbering sys-
tem. The hexadecimal system uses the digits 0 through 9 and the letters A through
F (uppercase or lowercase) to represent the decimal numbers 0 through 15. For
example, the hexadecimal letter D represents the decimal number 13. One hexa-
decimal digit is equivalent to 4 bits, and 1 byte can be expressed by two hexadeci-
mal digits.
Host name The DNS name of a device on a network, used to simplify the process
of locating computers on a network.
Hub A device that has multiple ports and that serves as a central connec-
tion point for communication lines from all devices on a network. When data arrives
at one port, it is copied to the other ports.
IEEE Acronym for `Institute of Electrical and Electronics Engineers'. A soci-
ety of engineering and electronics professionals that develops standards for the
electrical, electronics, computer engineering, and science-related industries. The
IEEE (Eye-triple-E) is a non-profit, technical professional association of more than
377,000 individual members in 150 countries. The full name is the Institute of Elec-
trical and Electronics Engineers, Inc., although the organization is most popularly
known and referred to by the letters I-E-E-E.
Infrastructure network A network configuration in which wireless devices con-
nect to a wireless access point (such as Watson) instead of connecting to each
other directly.
Internet domain In a networked computer environment, a collection of comput-
ers that share a common domain database and security policy. A domain is admin-
istered as a unit with common rules and procedures, and each domain has a
unique name.
Intranet A network within an organization that uses Internet technologies (such
a Web browser for viewing information) and protocols (such as TCP/IP), but is
available only to certain people, such as employees of a company. Also called a
private network. Some intranets offer access to the Internet, but such connections
are directed through a Firewall.
