DNS
Domain Name System is an Internet service that translates domain names into IP addresses. Since
domain names are alphabetic, they're easier to remember. The Internet however, is really based
on IP addresses every time you use a domain name the DNS will translate the name into the
corresponding IP address. For example, the domain name
www.network_camera.com
might
translate to
192.167.222.8
.

Ethernet
The most popular LAN communication technology. There are a variety of types of Ethernet,
including 10 Mbps (traditional Ethernet), 100 Mbps (Fast Ethernet), and 1,000 Mbps (Gigabit
Ethernet). Most Ethernet networks use Category 5 cabling to carry information, in the form of
electrical signals, between devices. Ethernet is an implementation of CSMA/CD that operates in a
bus or star topology.
F
Fast Ethernet
Fast Ethernet, also called 100BASE-T, operates at 10 or 100Mbps per second over UTP, STP, or
fiber-optic media.
Firewall

security, data can be encrypted. A system designed to prevent unauthorized access to or from a
private network. Firewalls are frequently used to prevent unauthorized Internet users from
accessing private networks connected to the Internet, especially Intranets all messages entering or

the numbers 0 to 9 and the letters A to F. For example, the decimal number 15 is represented as F
in the hexadecimal numbering system. The hexadecimal system is useful because it can represent
every byte (8 bits) as two consecutive hexadecimal digits. It is easier for humans to read
hexadecimal numbers than binary numbers.
I
IEEE
