USB
USB 1.1 – A device interface to your PC that supports desktops and laptops. Transfers data at speeds up to 12
Mbps.
USB 2.0 – A device interface to your PC that supports desktops and laptops. Transfers data at speeds up to 480
Mbps. It is also backwards compatible with USB 1.0/1.1.
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).
•802.11b (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.
