Glossary

Default gateway
The address representing the computer or router used when accessing a computer outside the local
network. If a specific gateway is not defined for the IP address being accessed, the data is sent to
the host specified by the default gateway.
DHCP (Dynamic Host Configuration Protocol)
DHCP is a protocol to automatically resolve IP addresses, subnet masks, and gateway addresses
on a TCP/IP network. Because it is not necessary to manually assign an IP address to each client
(including printers), it is especially useful to reduce the network management workload for networks
with many clients.
dpi (dots per inch)
A measure of image resolution. Indicates the number of dots in 1 inch (25.4mm).
FTP (File Transfer Protocol)
A protocol used to transfer files on TCP/IP networks such as the Internet or private intranets. Like
SMTP/POP, a protocol in common use on the Internet today.
Grayscale
A method of representing colors on a computer. Images are expressed in only shades of brightness
from black to white, including no color information, or 'monochrome.' The number of gray levels that
can be expressed is determined by the number of bits. 1 bit allows only black and white and no
intermediate levels, 8 bits allows 256 levels (including black and white) and 16 bit allows 65536 gray
levels.
IEEE1284
An international standard for connecting printers and computers. This standard was established in
1994 by the IEEE (Institute of Electrical and Electronic Engineers).
IP Address
An identification number assigned to every computer connected to a TCP/IP network. Represented
by 4 octets of numbers from 0 - 255, such as 192.168.110.171.
POP3 (Post Office Protocol 3)
A standard protocol used on the Internet and private intranets to receive electronic mail stored on a
server.
Send E-mail
A function to send scanned images to preset e-mail addresses or e-mail addresses entered by key
input.
SMTP (Simple Mail Transfer Protocol)
A protocol to deliver electronic mail over the Intranet or private intranets. SMTP is used to deliver
mail between servers and to send mail from an e-mail client to a server.
Subnet Mask
A 32 bit value that defines how many bits of an IP address are used to identify a network in a
network address.
TCP/IP (Transmission Control Protocol/Internet Protocol)
A network protocol to define data transmission standards for communication between computers
and other devices.
