DMZ Demilitarized Zone In computer security, DMZ is a physical or logical
sub-network that contains and exposes an
organization's external services to a larger distrusted
network, usually the Internet. The term is normally
referred to as a DMZ by IT professionals. It is
sometimes referred to as a Perimeter Network. The
purpose of a DMZ is to add an additional layer of
security to an organization's LAN (Local Area Network);
an external attacker only has access to equipment in
the DMZ, rather than any other part of the network.
DNS Domain Name System DNS is a distributed hierarchical naming system for
computers, services, or any resource connected to the
Internet or a private network. Most importantly, it
translates domain names meaningful to humans into
the numerical (binary) identifiers associated with
networking equipment for the purpose of locating and
addressing these devices worldwide.
DSCP Differentiated Service or
DiffServ
DSCP is a computer networking architecture that
specifies a simple, scalable and coarse-grained
mechanism for classifying, managing network traffic
and providing Quality of Service (QoS) guarantees on
modern IP networks. DiffServ can, for example, be
used to provide low-latency, guaranteed service (GS) to
critical network traffic such as voice or video while
providing simple best-effort traffic guarantees to
non-critical services such as web traffic or file transfers.
DiffServ uses the 6-bit Differentiated Services Code
Point (DSCP) field in the header of IP packets for
packet classification purposes. DSCP replaces the
outdated IP precedence, a 3-bit field in the Type of
Service byte of the IP header originally used to classify
and prioritize types of traffic.
DSL Digital Subscriber Line DSL is a family of technologies that provides digital
data transmission over the wires of a local telephone
network. In telecommunications marketing, the term
Digital Subscriber Line is widely understood to mean
Asymmetric Digital Subscriber Line (ADSL), the most
