DHCP

Dynamic Host Configuration Protocol was developed by Microsoft a

 

protocol for assigning dynamic IP addresses to devices on a network.

 

With dynamic addressing, a device can have a different IP address

 

every time it connects to the network. In some systems, the device’s

 

IP address can even change while it is still connected. DHCP also

 

supports a mix of 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. This means 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

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.

E

Enterprise network

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.

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

Firewall is considered the first line of defense in protecting private

 

information. For better 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 leaving the

 

intranet pass through the firewall, which examines each message and

 

blocks those that do not meet the specified security criteria.
