a two-phase authentication (user logon and network resource usage) on a depend-
able site set up on the network.
LAN
Abbreviation for Local Area Network. A network which connects computers on the
same floor, in the same building, or in neighboring buildings.
LDAP
Abbreviation for Lightweight Directory Access Protocol. On a TCP/IP network, such
as the Internet or an intranet, this protocol is used to access a database for manag-

MAC address
Abbreviation for Media Access Control address. With a special ID number for each
Ethernet card, data can be sent and received between the cards. A number consists
of 48 bits. The first 24 bits consist of a special number for each manufacture con-
trolling and assigning IEEE. The last 24 bits consist of a number that the manufac-
turer assigns uniquely to the card.
Memory
Storage device for storing data temporally. When the power is turned off the data
may or may not be erased.
MH
Abbreviation for Modified Huffman. A data compression encoding method for fax
transmissions. Documents containing mostly text are compressed to about 1/10
their original size.
MIB
Abbreviation for Management Information Base. In a TCP/IP transmission, this uses
SNMP to define the management information format for a group of network devices.
There are two formats: the manufacturer-specific private MIB and the standardized
MIB.
MMR
Abbreviation for Modified Modified Read. A data compression encoding method for
fax transmissions. Documents containing mostly text are compressed to about 1/20
their original size.
NetBEUI
Abbreviation for NetBIOS Extended User Interface. A network protocol developed
by IBM. By simply specifying the computer name, you can build a small-scale net-
work.
NetWare
Network operating system developed by Novell. NetWare IPX/SPX is used as the

NTLM
Abbreviation for NT LAN Manager. User authentication method used by Windows
NT or later. With the MD4 and MD5 encoding methods, passwords are encoded.
NTP
Abbreviation for Network Time Protocol. The protocol for correctly adjusting the
computer’s internal clock over the network. In a hierarchical method, the time is ad-
justed with the server at the highest level using GPS to acquire the correct time,
which is then referenced by each lower level host.
OCR
Abbreviation for Optical Character Reader. A device or software that converts hand-
written or printed documents to text data by optically scanning it and, through com-
parison with a previously stored pattern, specifies the characters.
OS
Abbreviation for Operating System. Basic software for controlling the system of a

PASV
Abbreviation for PASsiVe. A mode for connecting to an FTP server from within a fire-

dedicated server
Abbreviation for Portable Document Format. An electronically formatted document
which uses the .pdf extension. Based on the PostScript format, you can use the free

Pixel
An image pixel. The smallest unit of an image.
POP
Abbreviation for Post Office Protocol. A protocol for retrieving e-mail messages from
a mail server. Currently, POP3 (the third version of POP) is most often used.
POP Before SMTP
A user authentication method for sending e-mail messages. First, the reception op-
eration is performed and the user is authenticated by the POP server. Then, IP ad-
dresses where the user was successfully authenticated by the POP server are
permitted to use the SMTP server. This method prevents third parties without per-
mission to use the mail server from sending mail messages.
