ECC3 Flashcards
What is a network and what do it provide?
A network is a collection of devices, from
computers, to cell phones, that are interconnected by communication channels. Networks
provide for the sharing of resources and information.
Define the Department of Defense Information Network.
The DODIN is defined as the globally interconnected, end-to-end set of information
capabilities, associated processes, and personnel for collecting, processing, storing,
disseminating and managing information on demand for warfighters, policy makers, and
support personnel.
What is the Marine Corps Enterprise Network?
The MCEN includes all Marine Corps systems deployed or garrison right down to the
individual application on the desktop computer.
What is the Defense Information Systems Network?
e DISN as the integrated
network, centrally managed and configured to provide long-haul information transfer services
for all Department of Defense activities.
What are the USMC warfighting networks? Identify their respective characteristics.
The
majority of the training, administration, and garrison operations information flow on the
NIPRNET.
The SIPRNET or “Secret IP Data” is used for documents and information classified up to
the Secret level. Real world operations, combat operations, network information, and
other information are conducted over the SIPRNET.
MCEITS is the foundation of the Marine Corps cloud computing strategy, which envisions
access to it services and resources in a seamless manner, enhancing operational effectiveness
CANES is the shipboard network which enables collaborative information
sharing across forces afloat with reach-back capabilities to supporting shore establishments
CENTRIXS is the Combatant Commander’s network for coalition warfighting.
What are the four structural elements of a data network? Identify them individually.
1) Rules: Govern how messages flow across a network
2) Messages: The Information that travels over the medium
3) Medium: Method in which devices are connected
4) Devices: Items used to communicate with one another
What is convergence as it relates to data networking?
A converged network is one that can carry voice, video, and data over the same media and
infrastructure.
What are the three principles of information security?
Confidentiality, Integrity, and Availability.
What is an intermediary data device?
Intermediate data devices, such as switches and routers, fall in between the end devices. They are used to
forward information from one network to another one and ensure the smooth flow of data.
What is a local area network?
Networks commonly found in the same home, office, or
building, characterized by transmission speeds and minimum delay. All the computers at a
battalion or regimental command post would be on the same LAN. In figure 4-0, there are two
LANs, that of ECC and that of CTB.
What is a wide area network?
: Interconnects two high speed LAN networks over a
geographic distance; usually much slower than a LAN. WAN links are often found over
transmission paths. In figure 4-0, the WAN links connect ECC with CTB and could be carried
across SATCOM or terrestrial transmission equipment.
What is a protocol?
which is a set of logical rules that devices must follow to communicate or A protocol suite is a set of rules that work together to facilitate communication.
What is a standard as it pertains to data networking?
A standard is a protocol in the data world that has been endorsed by the networking industry and
ratified by a standards organization.
What are the layers of the updated TCP/IP model (figure 4-4)?
Application Transport Network Data Link Physical
What are the most common protocols used at the transport layer?
The two most commonly used protocols are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP)
