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
.
802.11g
An IEEE standard for wireless local area networks. It
offers transmissions speeds at up to 54 Mbps in the 2.4-
GHz band.
A
Access point
It is the hardware interface between a wireless LAN
and a wired LAN. The access point attaches to the
wired LAN through an Ethernet connection.
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
Dynamic Host Configuration Protocol was developed
by Microsoft a protocol for assigning dynamic IP
Page 115 / 127
114
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.
