Internet
This is a system of linked networks that are worldwide in scope and facilitates data communicate service such
as remote login, file transfer, electronic mail, the World Wide Web and newsgroups. With the meteoric rise of
demand for connectivity, the Internet has become the communications highway for millions of users. The
Internet was initially restricted to military and academic institutions in its infancy, but now it is a full-fledged
information channel for any and all forms of information and commerce. Internet web sites now provide
personal, educational, political and economic resources to every cornet of the planet.
IP Address
This address tells the network how to locate the computers or network equipment connected to it. IP
addresses are given so each computer or equipment on the network contains a unique address. There are
two methods used when assigning an IP address:
• Automatic (dynamic) Addressing
A DHCP (Dynamic Host Configuration Protocol) server assigns the IP address to each computer as
the computer connects to the network. If a computer moves to a new network (i.e., great for
temporary employees or mobile users), it must be assigned a new IP address for that network.
DHCP can be used to manage these assignments automatically.
• Manual (static) Addressing
Each device connected to the Internet must have its own unique IP address. Also, if a computer is
being used as a server, you will assign it a permanent IP address. This enables other computers to
connect to it. Static addressing is also beneficial to users that need to maintain a "constant"
connection to the Internet. This will enable users to easily access the IP address.
ISM (Industrial, Scientific, and Medical Bands)
Ranges are 900 to 928 MHz; 2.4 to 2.4835 GHz; and 5.725 to 5.85 GHz. The FCC for unlicensed use
allocated these bands with a restriction on the output power.
Isotropic
Uniform in all directions.
K
2
This is a polling protocol used in star networks (line of sight). A base station polls the remote stations (Customer
Premise Equipment) and tells when and where CPEs can transmit.
Kb/s
Thousands of bits per second.
