MHz (Mega Hertz): A measurement of millions of cycles per second.

MIB (Management Information Base): An internal database of commands and data structures used to define and profile the capabilities of the device for which it was written.

MIC (Message Integrity Check): A method of using a checksum to ensure a data message is not altered by a third party.

MIPS (Millions of Instructions Per Second): A measurement of processing speed.

NAT (Network Address Translation): An Internet standard that enables a LAN to use one set of IP addresses for internal traffic and a second set of addresses for external traffic.

NIC (Network Interface Card): An expansion board inserted into a computer so the computer can be connected to a network.

Packet: A block of data that is transferred as a single unit; also called a frame or a block.

Packet Filtering: Discarding unwanted network traffic based on its originating address or its type.

PCI (Peripheral Component Interconnect): A bus that is connected directly with the CPU.

PCMCIA (Personal Computer Memory Card International Association) Card: A PC card suitable for several types of applications.

Ping (Packet Internet Groper): An Internet utility used to determine whether a particular IP address is online.

Plug and Play: Hardware that, once installed ("plugged in"), can immediately be used ("played"), as opposed to hardware that requires manual configuration.

PoE (Power over Ethernet): A mechanism to send DC power to a device using a CAT5 Ethernet cable.

PPPoE (Point-to-PointTunneling Protocol): A specification for connecting users on an ethernet line to the internet through a common broadband medium.

Protocol: A standard way of exchanging information between computers.

RADIUS (Remote Authentication Dial In User Service): A server that issues authentication keys to clients.

RAM (Random Access Memory): Non permanent memory.

Repeater Hub: A device that collects, strengthens and transmits information to all connected devices, allowing the network to be extended to accommodate additional workstations.

RC4:The encryption algorithm that is used in WEP

RJ-45 connector: An8-pinconnector used for connecting twisted pair cable to a data transmissions device.


ROM (Read Only Memory): Permanent memory.

Router: A device that can connect individual LANs and remote sites to a server.

Roaming:The ability to use a wireless device and be able to move from one access point to another without losing the connection.

Script: A macro or batch file that contains instructions that the computer executes to perform a task.

Server: Any computer that makes access to files or peripheral devices available to users of the network.

SMTP (Simple MailTransfer Protocol): The protocol used to define and deliver electronic mail (e-mail) from one server to another.

SNMP (Simple Network Management Protocol): An application layer protocol that outlines the formal structure for communication among network devices.

Static IP Address: Also known as a global IP. A permanent IP address that is assigned to a node in a TCP/IP network.

STP (ShieldedTwisted Pair): See Twisted


Subnet Mask: An eight byte address divided into 4 parts grouped by periods.

TCP/IP (Transmission Control Protocol/Internet Protocol):The protocol used by computers when they communicate across the Internet or Intranets.

TFTP (Trivial FileTransfer Protocol): Simple form of FTP (File Transfer Protocol). Uses UDP (User Datagram Protocol) and provides no security features.

TKIP (Temporal Key Integrity Protocol): An encryption method replacing WEP. TKIP uses random IV and frequent key exchanges.

Topology:The shape of a LAN (Local Area Network) or other communications system.

Twisted Pair: Cable that comprises 2 or more pairs of insulated wires twisted together

UDP (User Datagram Protocol): A communication method (protocol) that offers a limited amount of service when messages are exchanged between computers in a network. UDP is used alternatively to TCP/IP.
