10Base-T/100Base-
TX/1000Base-T
A standard for Ethernet, which is connected through a cable consist-
ing 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.
Active Directory
A service that manages all information such as hardware resources 
for servers, clients, and printers on a network supported by Micro-
soft and the attributes and access permissions of the users
APOP
Abbreviation for Authenticated Post Office Protocol. An authentica-
tion method with encrypted passwords, which results in increased 
safety, as compared to the usual unencrypted passwords used by 
POP to retrieve e-mail messages
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.
BMP
Abbreviation for Bitmap. A file format for saving image data that 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 equal to 8 bits.
Client
A computer that uses the services provided by a server through a 
network
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
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.
DNS
Abbreviation for Domain Name System. A system that acquires the 
supported IP addresses from host names in a network environment. 
DNS allows the user to access other computers over a network by 
specifying host names, instead of difficult to memorize and under-
stand IP addresses.
