static and dynamic IP addresses. This simplifies the task for
network administrators because the software keeps track of
IP addresses rather than requiring an administrator to
manage the task. A new computer can be added to a
network without the hassle of manually assigning it a unique
IP address. DHCP allows the specification for the service
provided by a router, gateway, or other network device that
automatically assigns an IP address to any device that
requests one.
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.
An enterprise network consists of collections of networks
connected to each other over a geographically dispersed
area. The enterprise network serves the needs of a widely
distributed company and operates the company's mission-
critical applications.
The most popular LAN communication technology. There
are a variety of types of Ethernet, including 10Mbps
(traditional Ethernet), 100Mbps (Fast Ethernet), and
1,000Mbps (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.
Fast Ethernet, also called 100BASE-T, operates at 10 or
100Mbps per second over UTP, STP, or fiber-optic media.
