LEAP

Cisco Wireless EAP. EAP used by Cisco equipment to secure wireless networks with WEP-based devices.

LWAPP

The pending IETF (Internet Engineering Task Force) Lightweight Access Point Protocol standard defining communications between Wireless LAN Controllers and “Light” Access Points.

MAC

Medium Access Control. This is the function of a network controller that determines who gets to transmit when. Each network adapter must be uniquely identified. 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.

Mapping

Assigning a PC to a shared drive or printer port on a network.

MIC

Message Integrity Check. Used to ensure the integrity of a received message.

Mobile Device

See Client, Client Device.

Mobile Professional

A salesperson or a “road warrior” who travels frequently and requires the ability to regularly access his or her corporate networks, via the Internet, to post and retrieve files and data and to send and receive email.

NAT

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.

NetBIOS

Network Basic Input/Output System. An API, or set of network commands, which activates network data transfer operations between IBM PC compatibles.

Network Name

Identifies the wireless network for all the shared components. During the installation process for most wireless networks, you need to enter the network name or SSID. Different network names are used when setting up your individual computer, wired network or workgroup.

NIC

A type of PC adapter card that either works without wires (Wi-Fi) or attaches to a network cable to provide two-way communication between the computer and network devices such as a hub or switch. Most office wired NICs operate at 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet) or 10/100 Mbps dual speed. High-speed Gigabit and 10 Gigabit NIC cards are also available. See PC Card.

NOC

Network Operations Center. A location from which large communications networks are planned, moni- tored, and administered.
