GLOSSARY
3G
– “Third generation” mobile networks, specially designed for high speed data services. The classic
definition of wireless networks that following the 2G systems (GSM) and they offer high speed data
services in addition to the basic voice capability. These 3G mobile communications systems provide
an enhanced range of multimedia services (high speed Internet access, video streaming, etc.). The
high data transfer speed specific to the third generation communications network leads to an
increased efficiency of information transmission, while the real time access to data and information
means important savings of time and money. UMTS is the best known of the 3Gnetworks, while
HSDPA is a 3,5G development.
ANI
– Acronym for
Automatic Number Identification
- a feature of telephony intelligent network
services which allows subscribers to display or capture the telephone numbers of calling parties. The
service is often provided by sending the digital tone multi frequency (DTMF) tones along with the call.
Home users of ANI can screen callers. ANI is commonly used by emergency centre dispatchers to
save the caller having to report the information and, when necessary, to help locate callers. A
telephone company's 9-1-1 service to a public safety point usually includes the ANI feature. For
instance, in a call center, ANI displays the number of the calling party to the call center agent in real
time. Among other things, the call center can use the information to forward calls to different people for
different geographic areas.
DHCP
(Dynamic Host Configuration Protocol) - This protocol allows a computer (or many computers
on your network) to be automatically assigned a single IP address from a DHCP server. DHCP is
available on MobiLinkIP number that the caller dialled. DNIS works by passing the touch tone digits
(dual tone multi frequency or MF digits) to the destination where a special facility can read and display
them or make them available for call center programming. For example, a company may have a
different toll free number for each product line it sells. If a call center is handling calls for multiple
product lines, the switch that receives the call can examine the DNIS, and then play the appropriate
recorded greeting. Another example of multiple toll free numbers might be used for multi-lingual
identification. A dedicated toll free number might be set up for Spanish or Chinese speaking
customers.
DNS
– Acronym for Domain Name System (or Service), an Internet service that translates domain
names into IP addresses. This allows the Internet hosts to use both addresses type domain name
(such as topex.ro or linux.org), and addresses type IP numbers (for instance 192.17.3.4). The domain
name addresses are intended for human users and are automatically converted into IP (numeric)
addresses. Because domain names are alphabetic, they are much easier to remember. The Internet
however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS
service must translate the name into the corresponding IP address.
DNS Server
– computer able to answer to the interrogations in a DNS system. The DNS server
maintains a database that includes the host computers with their domain names and the
corresponding IP addresses. For instance, if you ask the DNS server for the domain name apex.com,
it will return the IP address of the hypothetical company called Apex. DNS servers are linked in their
network, so if one DNS server doesn't know how to translate a particular domain name, it asks another
one, and so on, until the correct IP address is found. When a user enters a domain name into the
Internet browser, the user is sent by the DNS Server to the proper IP address. The DNS server
address used by the computers on your home network is the location of the DNS
DNS Server Address
(Domain Name System) - DNS allows Internet host computers to have a
domain name and one or more IP addresses. A DNS server keeps a database of host computers and
their respective domain names and IP addresses, so that server your ISP has assigned.
Dynamic DNS
- service that allows clients connecting to the Internet with a dynamic IP address to be
able to use applications that require a static IP address. The Internet Service Provider changes the IP
address of the users, but there are applications that work only with static (fixed) IP addresses.
Dynamic DNS makes it possible for sites on the Internet to establish connections to you computer
without need for tracking the IP address themselves. DDNS is useful both for wired or wireless (such
as 3G) dialup connection where at each connection a new address is assigned, and for DSL services
where the address is changed occasionally by the ISP.
Domain Name Resolution -
The resolving of a domain name. Internet applications don’t
communicate with domain names such as google.com or topex.ro, instead they use IP addresses (for
example 193.226.61.95 or 216.239.39.99). Domain Name Resolution is the process (transparent for
