LAN
Local Area Network. A system of connecting PCs and other devices within the same physical proximity for sharing
resources such as an Internet connections, printers, files and drives. When Wi-Fi is used to connect the devices, the
system is known as a wireless LAN or WLAN.
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. 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.
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 email addresses and public keys.
Because LDAP is an open protocol, applications need not worry about the type of server hosting the directory.
Local User
A user that has signed up for an account from a specific ezboard community, enabling the user to participate only in
that ezboard as a registered user. Global user registration from the ezboard home page is recommended for full
access to all ezboard communities and the Control Center.
MAC
Media Access Control. Every wireless 802.11 device has its own specific MAC address hard-coded into it. This
unique identifier can be used to provide security for wireless networks. When a network uses a MAC table, only the
802.11 radios that have had their MAC addresses added to that network's MAC table will be able to get onto the
network.
Mbps
Megabits Per Second. One million bits per second; a unit of measurement for data transmission.
NAT
Network Address Translation.
A network capability that enables a houseful of computers to dynamically share a
single incoming IP address from a dial-up, cable or xDSL connection. NAT takes the single incoming IP address and
creates new IP address for each client computer on the network.
