known to waste bandwidth. AppleTalk, DECnet, TCP/IP, NetWare, and VINES all use incompatible versions of RIP. RJ-11 (Registered Jack-11) - A telephone connector that holds up to six wires. The RJ-11 is the common connector used to plug a telephone into a wall. RJ-45 - A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices. Router - Protocol-dependent device that connects sub networks together. Routers are useful in breaking down a very large network into smaller sub networks; they introduce longer delays and typically have much lower throughput rates than bridges. Routing Table - Is a user defined list of steps stating how to process various incoming traffic. Server - Any computer whose function in a network is to provide user access to files, printing, communications, and other services. Signal Strength - The amount of electromagnetic energy is present. A receiver (such as the one in your access point determines the strength of the signal for each wireless channel. Software - Instructions for the computer. A series of instructions that performs a particular task is called a "program." The two major categories of software are "system software" and "application software." System software is made up of control programs such as the operating system and database management system (DBMS). Application software is any program that processes data for the user. A common misconception is that software is data. It is not, software tells the hardware how to process the data. 105 SOHO (Small Office/Home Office) - Market segment of professionals who work at home or in small offices. Static IP Address - A permanent IP address that is assigned to a node in a TCP/IP network. SPI (Stateful Packet Inspection) - Maintains a log of sessions and requests for each application and determines if the conditions between the client and the application are "normal". If a request appears unrelated to the current application session, the request is denied. Static Routing - Forwarding data in a network via a fixed path. Static routing cannot adjust to changing line conditions as can dynamic routing. Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP address to form part of the host ID address field into a field for subnets. Switch - 1. A data switch connects computing devices to host computers, allowing a large number of devices to share a limited number of ports. 2. A device for making, breaking, or changing the connections in an electrical circuit. TCP (Transmission Control Protocol) - A method (protocol) used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP keeps track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet. TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic communication language or protocol of the Internet. It 106
