LDAP
A set of protocols for accessing information directories.
Lightweight Directory Access Protocol
LDAP. A set of protocols for accessing information directories.
LDAP is based on the standards contained within the X.500 standard, but is significantly simpler. And
unlike X.500, LDAP supports TCP/IP, which is necessary for any type of Internet access. Because it's a
simpler version of X.500, LDAP is sometimes called
X.500-lite.
local area network
LAN. 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.
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.
Mbps
Megabits per second.
MDI/MDIX
In cable wiring, the concept of transmit and receive are from the perspective of the computer, which is wired
as a Media Dependant Interface (MDI). In MDI wiring, a computer transmits on pins 1 and 2. At the hub,
switch, router, or access point, the perspective is reversed, and the hub receives on pins 1 and 2. This wiring
is referred to as Media Dependant Interface - Crossover (MDI-X). See also AES.
Maximum Receive Unit
The size in bytes of the largest packet that can be sent or received.
Maximum Transmit Unit
The size in bytes of the largest packet that can be sent or received.
Most Significant Bit or Most Significant Byte
MSB. The portion of a number, address, or field that is farthest left when written as a single number in
conventional hexadecimal ordinary notation. The part of the number having the most value.
MRU
The size in bytes of the largest packet that can be sent or received.
MSB
MSB. The portion of a number, address, or field that is farthest left when written as a single number in
conventional hexadecimal ordinary notation. The part of the number having the most value.
