The wireless standard operation gin the 5Ghz range providing for up to 54Mbps of throughput and a maximum range of 250 feet indoors.
|
802.11a
|
|
|
The wireless standard in general use today. It operates in the frequency range of 24 GHz and offer throughput of up to 54Mbps with a maximum indoor range of 300 feet.
|
802.11g
|
|
|
Each wireless in this network is in direct contact with every other node in a decentralized free-for-all. Similar to mesh topologies.
|
Ad-Hoc Mode
|
|
|
An implementation of DSL where the upload and download speeds are different. The most common type used in home-user networks.
|
ADSL
|
|
|
The new routing method used by InterNIC to assign IP Addresses. Can be described as "slash x" networks with x representing the number of bits in the network that InterNIC controls.
|
Classless Inter-Domain Routing (CIDR)
|
|
|
A physical or logical subnetwork that contains and exposes an organization's external services to a larger, untrusted network, usually the Internet.
|
Demilitarized Zone
|
|
|
A modulation technique used by the original IEEE 802.11 standard, as well as by the 802.11b standard. This creates a redundant bit pattern for each bit transmitted so that if one or more bits in the pattern are damaged in transmission, the original data might be recoverable from the redundant bits.
|
Direct-Sequence Spread Spectrum
|
|
|
A high-speed Internet connection technology that uses a regular telephone line for connectivity. It comes in several varieties - Asynchronous and Synchronous being the most common with Asynchronous the most common in home-use.
|
DSL
|
|
|
A combination of hardware and software that protects a network from attack by hackers that could gain access through public networks, including the Internet.
|
Firewall
|
|
|
A spread-spectrum broadcasting method defined in the 802.11 standard that sends data on one frequency at a time, constantly shifting frequencies.
|
Frequency Hopping Spread Spectrum
|
|
|
Wireless networks running in the mode use one or more wireless access points to connect the wireless network nodes centrally. This configuration is similar to the star topology or a wired network.
|
Infrastructure Mode
|
|
|
A TCP/IP service that many routers, firewalls and IP proxies provide to translate Private IP addresses to Public IP addresses.
|
Network Address Translation
|
|
|
The public telephone network. It is also called the plain old telephone service or POTS.
|
Publicly Switched Telephone Network
|
|
|
A 32-bit identification string, sometimes called a network name, that is inserted into the header of each data packet processed by a wireless access point.
|
SSID
|
|
|
The value used in TCP/IP settings to divide the IP address of a host into its component parts - network ID and host ID.
|
Subnet Address
|
|
|
A leased-line connection with a maximum speed or 1.5 Mbps over two copper wires.
|
T-1 Connection
|
|
|
A leased-line connection with a maximum speed of up to 44 Mbps over multiple copper wires.
|
T-3 Connection
|
|
|
The part of a Network Interface Card that transmits and receives network signals.
|
Transceiver
|
|
|
The most widely adopted wireless networking type in use today. Technically, only wireless devices that conform to the extended versions of the 802.11 standard - 802.11a, 802.11b and 802.11g - are certified as this type of network.
|
Wi-Fi
|
|
|
The standard that improves upon the original design of WEP that is backward compatible with WEP devices. It provides enhanced security by adding two main computers - TKIP and user authentication.
|
Wi-Fi Protected Access (WPA)
|
|
|
A wireless security protocol that uses a 64-bit encryption algorithm to scramble data packets.
|
Wired Equivalent Privacy (WEP)
|
|
|
The access point for connecting devices in a wireless network to other wireless devices, or to the wired portion. Many of these devices are combination devices that act as high-speed hubs, switches, bridges, and routers, all rolled into one.
|
Wireless Access Points (WAPs)
|
|
|
A protocol that is use to communicate between the remote-access device and an authentication server.
|
RADIUS
|
|
|
A standard in the US that defines a base date rate of 51.84 Mbps. Multiples of this rate are known as optical carrier (OC) levels, such as OC-3, OC-12, etc.
|
SONET
|
|
|
The precise spot where the service provider's responsibility ends and the company's responsibility begins. It is generally a device in a telephone communications closet owned by the phone company.
|
Demarcation Point
|
