DNS The acronym for Domain Name System. DNS allows for obtaining the
IP address corresponding to a host name in network environments.
This system enables a user to access other computers on the network
by specifying host names instead of elusive and non-intuitive IP ad-
dresses.
DPI (dpi) The acronym for Dots Per Inch. A unit of resolution used for printers
and scanners. This indicates the number of dots used to represent an
inch. The higher this value, the higher the resolution.
Driver Software that works as a bridge between a computer and a peripheral
device.
Ethernet A standard for LAN transmission lines.
File extension Characters added to a file name for the recognition of the file format.
The file extension is added after a dot of a file name, for example,
".bmp" or ".jpg".
FTP The acronym for File Transfer Protocol. This is a protocol used for
transferring files via the Internet, an intranet or other TCP/IP network.
Gradation The shading levels of an image. Larger number of the levels can re-
produce smoother transition of the shading.
Gray scale A form of presenting monochrome image by using the gradation infor-
mation shifting from black to white.

sizes of black and white dots.

IP Address An address or a code used to identify an individual network device on
the Internet. IPv4 (Internet Protocol version 4), a protocol widely used

sections. An example of an IPv4 IP address is: 192.168.1.10. On the
other hand, IPv6 (Internet Protocol version 6), the next generation pro-
tocol, adopts 128-bit IP addresses. An IP address is assigned to every
computer or other device connected to the Internet.
JPEG The acronym for Joint Photographic Experts Group, One of the file
formats used to save image data. (The file extension is ".jpg".) The
compression ratio is generally 1/10 to 1/100. JPEG is an effective
method to compress photographs and other natural images.
Kerberos A network authentication system used for Windows 2000 or later,
used as the Active Directory authentication. Kerberos arranges an au-
thentic site within the network to provide two-phase authentication
processes of users login and the use of network resources, allowing
users to be securely and efficiently authenticated.

by connecting computers on the same floor, in the same building, or
in neighboring buildings.

used to access a database that can manage E-mail addresses and
