10Base-T/100Base-TX/
1000Base-T
An Ethernet standard, which is a cable consisting of twisted copper
wire pairs. The transmission speed of 10Base-T is 10 Mbps, of
100Base-TX is 100 Mbps, and of 1000Base-T is 1000 Mbps.
anonymous FTP While normal FTP sites are protected by an account name and pass-
word, this type of FTP site can be used by anyone without a pass-
word by simply entering “anonymous” as the account name.
Auto IP A function for automatically acquiring the IP address. If acquisition
of the IP address failed with DHCP, an IP address is acquired from
the address space of 169.254.0.0.
bit Abbreviation for Binary Digit. The smallest unit of information (data
quantity) on a computer or printer. Displays data using 0 or 1.
Bit-mapped Font Fonts that are represented by a set of dots to form the character.
Dithering may occur if the character size is increased.
BMP Abbreviation for Bitmap. A file format for saving image data which
uses the .bmp extension. Commonly used on Windows platforms.
You can specify the color depth from monochrome (2 values) to full
color (16,777,216 colors). Images are not usually compressed when
saved.
Byte Unit of information (data quantity) on a computer or printer. Config-
ured as 1 byte equals 8 bits.
Compact PDF Compression method for reducing the data amount using the PDF
format when converting color documents to data.
The highest compression efficiency is achieved by identifying the
text and image regions and using the resolution and compression
method most appropriate for each region.
The compact PDF format can be selected when converting docu-
ments to data using the scanning functions of this machine.
Contrast The difference in intensity between the light and dark parts of the im-
age (light/dark variation). An image with little light/dark variation is
said to have a low contrast, and an image with large light/dark vari-
ation is said to have a high contrast.
Default The initial settings. The settings first selected when the machine is
turned on, or the settings first specified when the function is select-
ed.
Default Gateway A device, such as a computer or router, used as a “gateway” to ac-
cess computers not on the same LAN
Density An indication of the amount of darkness in the image
Density Adjustment The function that adjusts the color tones of an output device, such
as a printer or monitor
DHCP Abbreviation for Dynamic Host Configuration Protocol. A protocol in
which a client computer on a TCP/IP network automatically specifies
the network settings from the server. With collective management of
the IP address for DHCP clients on the DHCP server, you can avoid
duplication of an address and you can build a network easily.
Dither A method of using only black and white to create the illusion of dif-
ferent shades of gray. The process is simpler than with error diffu-
sion; however, some irregularities may occur.
