Ethernet
A networking standard using cables (Category 5) to create a network.
Network Adapter
Also known as a NIC (Network Interface Card). Used to provide PC’s or laptops with an Ethernet port or wireless access to the network.
Broadband Modem
A device that allows broadband connection to the internet. Broadband connections include speeds faster than 56k (dial up modem speed ). The two
most common types of Broadband connections are DSL and Cable. Cable modem relies on the bandwidth of cable television lines while DSL
modems rely on the telephone lines operating at DSL speeds.
Router
A device used to share internet access from one user to multiple users. By taking one IP address (Addresses used by ISP’s to assign broadband
services to your computer) the Router distributes the services of your broadband access among multiple users and IP’s.
Wireless
IEEE 802.11 – Wireless Network Specifications
•
802.11
-- applies to wireless LANs (Networks) and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency
hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).
•
802.11a
-- an extension to 802.11 that applies to wireless LANs and provides up to 54 Mbps in the 5GHz band. 802.11a uses an
orthogonal frequency division multiplexing encoding scheme rather than FHSS or DSSS.
•
802.11b
(also referred to as
802.11 High Rate
or
Wi-Fi
) -- an extension to 802.11 that applies to wireless LANs and provides 11 Mbps
transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. 802.11b uses only DSSS. 802.11b was a 1999 ratification to the
original 802.11 standard, allowing wireless functionality comparable to Ethernet.
•
802.11g
-- applies to wireless LANs and provides 54 Mbps in the 2.4 GHz band. Backwards compatible with IEEE 802.11b products.
ESSID
A unique name identification for your wireless network. All wireless devices must have the same ID or else they will not work together.
Channel
A Channel that all Wireless devices communicate on. All Wireless devices on the network must be set on the same channel to work.
