Flashcards in 6 Day 1 Deck (37):
What is a set of rules that allows computers to establish and maintain useful communications at various levels?
Computers simply connect with each other in a workgroup to share files, printers, and Internet access. There is no server.
There is usually a central server to which all computers logon. The central server can provide various services, including centrally routed Internet access, email, file sharing, and printer access, as well as ensuring security across the network.
Which topology has a concentrator/hub device that acts as a central point for all cabling?
This topology is normally built as a series of devices, daisy chained with successive coaxial cable and appropriate connectors and terminators.
What is the collection of networks owned and managed by the DoD?
DoD Information Network (DoDIN)
What three networks are part of the collection owned by the DoD?
Non-classified Internet Protocol Router Network (NIPRNet)
Secret Internet Protocol Router Network (SIPRNet)
Joint Worldwide Intelligence Communications System (JWICS)
Using the proper formula, how many links are needed to connect seven nodes in a full mesh topology?
What term is used to describe an intranetwork?
Local Area Network (LAN)
What term is used to describe an internetwork?
Wide Are Network (WAN)
What are the two main types of twisted-pair cabling?
What problems does the use of fiber optic cabling eliminate?
Radio Frequency Interference
Which type of fiber optic cabling uses LEDs as a light source?
What replaces the network adapter cable interface so that wireless media can be accessed?
Consists of multiple devices connecting to a single device in order to communicate.
Computers on the network communicate with the central device but not with one another.
What are the two orbits of a satellite:
Combination of voice, data, video, pictures and many other features.
Practical application of a topology and other critical tech to provide a method to get data from one computer to another.
What are polyvinyl chloride (PVC) and plenum?
The two most common fire ratings
Which organization "defines industry-wide standards that promote the use and implementation of technology?"
Which committee was developed to set the standards for networking but later split into subcommittees called working groups?
Formula to determine the number of connections required for a full mesh topology.
