The wireless standard operating in the 5Ghz range providing for up to 54 Mbps of throughput and a maximum range of 250 feet indoors
The wireless standard in general use today. It operates in the frequnecny range of 24GHz and offter throughput of up to 54 Mbps with a maximum indoor range of 300 ft
Each wireless in this network is in direct contact with every other node in a decenteralized free-for-all. Similar to mesh toplogies.
Ad-Hoc Mode
An implementatin of DSL where the upload and download speeds are different . The most common type used in home-use networks.
The new routing method used by InterNIC to assign IP addresses. can be descirbed as "slash x" networks, with x representing the number of bits in the network that the InterNIC controls.
Classless Inter-Domain Routing (CIDR)
a physical or logical subnetwork that contains and exposes and orgainzation's external services to a larger, untrusted network, usually the internet.
Demilitarized Zone
A modulation technique used by the original IEEE 802.11 standeard, as well as by the 802.11b standard. this creates a redundant bit pattern for each bit transmitted so that it 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.
a combination of hardware and software that protects a network from attack by hackers that could gain access through public networks including the internet
a spread-spectrum broadcasting method defined in the 802.11 standard that sends data on one frequency at a time, constantly shifting frequenceis
Frequncey Hopping Spread Spectrum
wireless networks running in this mode us one or more wireless access points to connect the wireless network nodes centrally. This configuration is similar to the star topology of 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 telphone network. It is also called plain old telephone services 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
The value used in TCP/IP settings to divide the IP address of a host into its componets parts- network ID and Host ID
Subnet address
A leased-line connection with a maximum speed of 1.5 Mbps over two copper wires.
T-1 Connection
A lease line connection with a maximum sspeed 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.
The most widely adopted wireless networking type in use today. Technically, only wireless devices that conform to extended verisons of the 802.11 standard- 802.11a, 802.11b, and 802.11g- are certified as this type of network
The standard that improves upon the original design of WEP that is backward compatible with WEP devices. It provides enchaneced security by adding two main componets- TKIP and user authentication
Wi-Fi Protected Access (WPA)
A wireless security protocol that uses a 64 bit encruption algorithm to scramble data packets
Wired Equivalent Privacy (WEP)
The access point for connection devices in a wireless network to other wireless devices or to the wired porition. Many of these devices are combination devices that act as high-speed hubs, switches, brideges, and routers, all rolled into one
Wireless Access Points (WAPs)
A protocol that is used to communicate between the remote access device and authentication server.
A standard in the US that defines a base date rate of 51.84 Mbps. Multiples of this rate are know as optical carrier (OC) leverls, such as OC-3, OC-12, etec
The precise spot where the service provider's responsibility ends and the compnay's responsibility begins. It is gernerally a device in a telphone communications closet owened by the phone company
Demarcation Point.
