Question | Answer |
---|---|
access point (AP) | A device connected to a LAN that provides wireless communication so that computers, printers, and other wireless devices can communicate with devices on the LAN. |
adapter address | A 48-bit hardware address unique to each NIC card or onboard network controller and assigned by the manufacturer. The address is often printed on the adapter as hexadecimal numbers. |
AirPort | The term Apple computers use to describe the IEEE 802.11b standard. |
amplifier repeater: attenuation | a repeater that does not distinguish between noise and signal; it amplifies both |
Automatic Private IP Address (APIPA) | An IP address in the address range 169.254.x.y, used by a computer when it cannot successfully lease an IP address from a DHCP server. |
bandwidth | In relation to analog communication, the range of frequencies that a communications channel or cable can carry. In general use, the term refers to the volume of data that can travel on a bus or over a cable stated in bits per second. |
base station | A fixed transceiver and antenna used to create one cell within a cellular network. |
binding | the process by which a protocol is associated with a network card or modem |
Bluetooth | A standard for wireless communication and data synchronization between devices, developed by a group of electronics manufacturers and overseen by the Bluetooth Special Interest Group. Bluetooth uses the same frequency range as 802.11b. |
BNC connector | A connector used with thin coaxial cable. Some BNC connectors are T-shaped and called T-connectors. One end of the T connects to the NIC, and the two other ends can connect to cables or end a bus formation with a terminator. |
broadband | A transmission technique that carries more than one type of transmission on the same medium, such as voice and DSL on a regular telephone line. |
broadcast | Process by which a message is sent from a single host to all hosts on the network, without regard to the kind of data being sent or the destination |
bus topologycellular network | a LAN architecture in which all the devices are connected to a bus, or one communication line. topology does not have a central connection point. |
cellular WAN | A network that can be used when a wireless network must cover a wide area. The network is made up of cells, each controlled by a base station. |
classful subnet masks | A subnet mask that contain all ones or all zeroes in an octet. |
classless subnet masks | A subnet mask that can have a mix of zeroes and ones in one octet. |
client | the computer that is requesting information from the server computer. |
client/server | A computer concept whereby one computer (the client) requests information from another computer (the server). |
coaxial cable | Networking cable used with 10-Mbps Ethernet ThinNet or ThickNet. |
computer name | Character-based host name or NetBIOS name assigned to a computer. |
crossover cable | A cable used to connect two PCs into the simplest network possible. Also used to connect two hubs to two switches. |
data throughput | the range of frequencies that a communications channel or cable can carry. In general use, the term refers to the volume of data that can travel on a bus or over a cable stated in bits per second. Also known as Bandwidth |
