Getting Connected

Post by luckyman »

802.11: A set of protocols for wireless communication. The 802.11 protocols occupy the Network Access layer of the TCP/IP stack, which is equivalent to the OSI Data Link and Physical layers.

Access point: A device that serves as a connecting point from a wireless network to a conventional network. An access point typically acts as a network bridge, forwarding frames to and from a wireless network to a conventional ethernet network.

Association: A procedure in which a wireless device registers its affiliation with a nearby access point.

Bluetooth: A protocol architecture for wireless appliances and devices in close proximity.

Bridge: A connectivity device that forwards data based on physical address.

Cable modem termination system (CMTS): A device that serves as an interface from a cable modem connection to the provider network.

Cut-through switching: A switching method that causes the switch to start forwarding the frame as soon as it obtains the destination address.

Data Over Cable Service Interface Specification (DOCSIS): A specification for cable modem networks.

Digital subscriber line (DSL): A form of broadband connection over a telephone line.

Digital subscriber line access multiplexer (DSLAM): A device that serves as an interface from a DSL connection to the provider network.

Hub: A connectivity device to which network cables are attached to form a network segment. Hubs typically do not filter data and instead retransmit incoming frames to all ports. The once-common hub has now been replaced by the switch, but hubs are still important for understanding the evolution of LAN networking devices.

Independent basic service set (Independent BSS or IBSS): A wireless network consisting of two or more devices communicating with each other directly (also known as an ad hoc network).


Infrastructure basic service set (Infrastructure BSS): A wireless network in which the wireless devices communicate through one or more access points connected to a conventional network.

Intelligent Hub: A hub capable of performing additional tasks such as blocking off a port when a line problem is detected.

Link Control Protocol (LCP): A protocol used by PPP to establish, manage, and terminate dial-up connections.

Mobile IP: An IP addressing technique designed to support roaming mobile devices.

Modem: A device that translates a digital signal to or from an analog signal.

Network control protocol (NCP):" One of a family of protocols designed to interface PPP with specific protocol suites.

Point-to-point connection: A connection consisting of exactly two communicating devices sharing a transmission line.

Point-to-point Protocol (PPP): A dial-up protocol. PPP supports TCP/IP and also other network protocol suites. PPP is newer and more powerful than SLIP.

Serial Line Internet Protocol (SLIP): An early TCP/IP -based dial-up protocol.

Store-and-forward switching: A switching method that causes the switch to receive the entire frame before retransmitting.

Switch: A connectivity device. A switch is aware of the address associated with each of its ports and forwards each incoming frame to the correct port. Switches can base forwarding decisions on a variety of parameters encapsulated in the headers of the protocol stack.

Wide area network (WAN): A collection of technologies designed to provide relatively fast and high-bandwidth connections over large distances.

Wi-Fi Protected Access II (WAP2): An advanced wireless security standard that has largely replaced WEP, WPA2 uses an AES block cipher for encryption.

Wired Equivalent Privacy (WEP): A standard for security on 802.11 wireless networks. WEP is now considered obsolete.
