Description
A set of specifications under the Ethernet standards.
Those cables that consist of twisted copper wire pairs are used. The transmis-
sion speed of 10Base-T is 10 Mbps, of 100Base-TX is 100 Mbps, and of
1000Base-T is 1000 Mbps.
®
Software or its file format developed by Adobe Systems Inc. (formerly by Mac-
romedia, Inc.), used to create a content by compiling vector-graphic animations
and sounds. The software allows handling interactive contents using keyboard
or mouse. The files can be kept relatively compact and accessed from a Web
browser with dedicated plug-in software.
While normal FTP sites are protected by an account name and password, this
type of FTP site can be used by anyone without a password by simply entering
anonymous as the account name.
A function that allows you to print the job sent from the printer driver during user
authentication.
A function to obtain an IP address automatically.
If one fails to get an IP address via DHCP, the auto IP gets an IP address from
the space of "169.254.0.0".
The abbreviation of Binary Digit. The smallest unit of information (data quantity)
handled by a computer or printer. A bit uses only a 0 or a 1 to indicate data.
A font using a collection of dots to present characters. Jagged edges are con-
spicuous for the larger size Bitmap Font characters.
The abbreviation for Bitmap. It is a file format used to save image data. (The file
extension is ".bmp"). Commonly used on Windows platforms. BMP covers the
color depth from monochrome (2 values) to full color (16,777,216 colors). BMP
is basically used to save images without compression.
A byte indicates a unit of information (data quantity) handled by a computer or
printer.
A byte consists of eight bits.
A compression method for minimizing the data size using the PDF format, used
for digitalizing color documents. Compact PDF allows high compression per-
formance by identifying the text and image regions, and applying the resolution
and compression method optimized for each region. The compact PDF method
can be selected in this machine when using the scanning function to digitalize
documents.
The difference in intensity between the light and dark parts of the image
(light/dark variation). "Low contrast" indicates an image with little light/dark var-
iation, while "High contrast" an image with large light/dark variation.
An initial setting. The settings selected in advance and enabled when the ma-
chine is turned on, or the settings selected in advance and enabled when the
function is activated.
A device, such as a computer or router, used as a "gateway" to access comput-
ers on different LANs.
The amount of density of an image.
A color tone correction function used for output devices such as printers and dis-
plays.
The acronym for Dynamic Host Configuration Protocol, used for a client compu-
ter on the TCP/IP network to load network configuration automatically from a
server. The centralized management of DHCP client IP addresses assumed by a
DHCP server enables you to construct a network without an IP address duplica-
tion or other troubles.
A method of presenting the quasi-shading of gray using black and white colors.
This method is easier to process than error diffusion, but may stir some uneven-
ness on the image.
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 another computer on the network by specifying a host name in-
stead of an elusive and non-intuitive IP address.
