A.4 Glossary of Terms

NUMBERS

10BASE-T

10BASE-T is Ethernet over UTP Category III, IV, or V unshielded twisted-pair media.

100BASE-TX

The two-pair twisted-media implementation of 100BASE-T is called 100BASE-TX.

A

ADPCM

Adaptive Differential Pulse Code Modulation, a new technology improved from PCM,

 

which encodes analog sounds to digital form.

AMR

AMR (Adaptive Multi-Rate) is an audio data compression scheme optimized for speech

 

coding, which is adopted as the standard speech codec by 3GPP.

Applet

Applets are small Java programs that can be embedded in an HTML page. The rule at

 

the moment is that an applet can only make an Internet connection to the computer

 

form that the applet was sent.

ASCII

American Standard Code For Information Interchange, it is the standard method for

 

encoding characters as 8-bit sequences of binary numbers, allowing a maximum of 256

 

characters.

ARP

Address Resolution Protocol. ARP is a protocol that resides at the TCP/IP Internet layer

 

that delivers data on the same network by translating an IP address to a physical

 

address.

AVI

Audio Video Interleave, it is a Windows platform audio and video file type, a common

 

format for small movies and videos.

B

BOOTP

Bootstrap Protocol is an Internet protocol that can automatically configure a network

 

device in a diskless workstation to give its own IP address.

C

 

Communication

Communication has four components: sender, receiver, message, and medium. In

 

networks, devices and application tasks and processes communicate messages to

 

each other over media. They represent the sender and receivers. The data they send is

 

the message. The cabling or transmission method they use is the medium.

Connection

In networking, two devices establish a connection to communicate with each other.

D

 

DHCP

Developed by Microsoft, DHCP (Dynamic Host Configuration Protocol) is 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. It 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. 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.
