Term Description
10Base-T/
100Base-TX/
1000Base-T
A set of specifications under the Ethernet standards. Those cables
that consist of twisted copper wire pairs are used. The transmission
rates are 10Mbps with 10Base-T, 100Mbps with 100Base-TX and
1000Mbps with 1000Base-T.
bit The abbreviation for 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.
BMP The abbreviation for bitmap. This is a file format for saving image da-
ta. (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 images are not suitable for compressed storage.
BOOTP The abbreviation for Bootstrap Protocol. The protocol is used for a
client computer on the TCP/IP network to load network configura-
tion automatically from a server. Instead of BOOTP, DHCP, an ad-
vanced protocol based on BOOTP, is typically used today.
Brightness Brightness of a display or other screen.
Byte A byte indicates a unit of information (data quantity) handled by a
computer or printer. A byte consists of eight bits.
Client A computer using services provided by servers via the network.
Default Gateway A device, such as a computer or router, used as a "gateway" to ac-
cess computers on different LANs.
DHCP The acronym for Dynamic Host Configuration Protocol. The protocol
is used for a client computer on the TCP/IP network to load network
configuration automatically from a server. Just using a DHCP server
to centrally manage IP addresses of the DHCP clients enables you
to construct a network without IP address conflicts or other troubles.
DNS The acronym for Domain Name System. DNS allows for obtaining
the IP address corresponding to a host name in network environ-
ments. This system enables a user to access other computers on the
network by specifying host names instead of elusive and non-intui-
tive IP addresses.
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 periph-
eral device.
Ethernet A standard for LAN transmission lines.
Frame type A type of communication format used in NetWare environments. For
mutual communication, the same frame type is required.
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.
Gateway Hardware and software used as the point where a network is con-
nected to a network. A gateway not only connects networks but also
changes data formats, addresses, and protocols according to the
connected networks.
Gray scale A form of presenting monochrome image by using the gradation in-
formation shifting from black to white.
