Ethernet
A networking standard using cables (Category 5) to create a network.
1 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.
2 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.
3 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
4 Wireless Device Any WiFi device (802.11b/g) that communicates
wirelessly using the IEEE802.11 wireless standard. These devices
can range from wireless access points to wireless routers to wireless
PCI client cards.
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).
802.11b (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.
