LAN
LDAP
Lightweight Directory Access Protocol
A set of protocols for accessing information directories. LDAP is based on the standards contained within 
the X.500 standard, but is significantly simpler. Unlike X.500, LDAP supports TCP/IP, which is necessary 
for any type of Internet access. Although not yet widely implemented, LDAP should eventually make it 
possible for almost any application running on virtually any computer platform to obtain directory 
information, such as e-mail addresses and public keys. Because LDAP is an open protocol, applications 
need not worry about the type of server hosting the directory. 
Local Area Network
A communications network serving users within a limited area, such as one floor of a building. A LAN 
typically connects multiple personal computers and shared network devices such as storage and printers. 
Although many technologies exist to implement a LAN, Ethernet is the most common for connecting 
personal computers and is limited to a distance of 1,500 feet. LANs can be connected together, but if 
modems and telephones connect two or more LANs, the larger network constitutes what is called a WAN or 
Wide Area Network. 
M
MAC
(1) Media Access Control. In LANs, the sublayer of the data link control layer that supports 
medium-dependent functions and uses the services of the physical layer to provide services to the logical 
link control (LLC) sublayer. The MAC sublayer includes the method of determining when a device has 
access to the transmission medium. (2) Message Authentication Code. In computer security, a value that is a 
part of a message or accompanies a message and is used to determine that the contents, origin, author, or 
other attributes of all or part of the message are as they appear to be. (IBM Glossary of Computing Terms)
MAC address
The Media Access Control address is a unique 48-bit hardware address assigned to every network interface 
card. Usually written in the form 01:23:45:67:89:ab.
