NETWORK+ Terms I's Flashcards
1
Q
An organization responsible for IP addresses, domain names, and protocol parameters. Some functions of IANA, such as domain name assignment, have been devolved into other organizations.
A
IANA (Internet Assigned Numbers
Authority)
2
Q
A network layer Internet protocol documented in RFC 792 that reports errors and provides other information relevant to IP packet processing. Utilities such as ping and tracert use functionality provided by ICMP.
A
ICMP (Internet Control Message
Protocol)
3
Q
The use of one device with access to
the Internet as an access point for
other devices to connect.
A
ICS (Internet Connection Sharing)
4
Q
Some networks use multiple wiring closets. When this is the case, the wiring closet, known as the main distribution frame (MDF), connects to secondary wiring closets, or intermediate distribution frames (IDFs). See also MDF.
A
IDF
5
Q
A software application or hardware device that monitors a network or system for malicious or nonpolicy related activity and reports to a centralized management system.
A
IDS (Intrusion Detection System)
6
Q
IEEE (Institute of Electrical and Electronics Engineers) A professional organization that, among other things, develops standards for networking and communications.
A
IEEE (Institute of Electrical and
Electronics Engineers)
7
Q
IEEE 1394
A
A standard that defines a system for connecting up to 63 devices on an external bus. IEEE 1394 is commonly used with consumer electronic devices such as video cameras and MP3 players. IEEE 1394 is based on a technology developed by Apple Computers called FireWire.
8
Q
A standard that defines the OSI model’s physical and data link layers. This standard allows two IEEE LAN stations to communicate over a LAN or WAN and is often called the internetworking standard.
A
IEEE 802.1
9
Q
An IEEE security standard designed for authenticating wireless devices. This standard uses Extensible Authentication Protocol (EAP) to provide a central authentication server to authe
A
IEEE 802.1X
10
Q
A standard that defines the LLC sublayer of the data link layer for the entire series of protocols covered by the 802.x standards. This standard specifies the adding of header fields, which tell the receiving host which upper layer sent the information.
A
IEEE 802.2
11
Q
A standard that specifies physical layer attributes, such as signaling types, data rates, and topologies, as well as the media access method used. It also defines specifications for the implementation of the physical layer and the MAC sublayer of the data link layer, using CSMA/CD. This standard also includes the original specifications for Fast Ethernet.
A
IEEE 802.3
12
Q
A standard that defines how production machines should communicate. It establishes a common protocol for use in connecting these machines. It also defines specifications for the implementation of the physical layer and the MAC sublayer of the data link layer, using
A
IEEE 802.4
13
Q
A standard used to define token ring. However, it does not specify a particular topology or transmission medium. It provides specifications for the implementation of the physical layer and the MAC sublayer of the data link layer, using a token-passing media access method on a ring topology.
A
IEEE 802.5
14
Q
A standard that defines
the distributed queue dual-bus technology
to transfer high-speed data
between nodes. It provides specifications
for the implementation of
MANs.
A
IEEE 802.6
15
Q
A standard that defines
the design, installation, and testing
of broadband-based communications
and related physical media connectivity.
A
IEEE 802.7
16
Q
A standard that defines the Fiber Optic Technical Advisory Group, which advises the other 802 standards committees on various fiberoptic technologies and standards.
A
IEEE 802.8
17
Q
A standard that defines
the integration of voice and data
transmissions using isochronous
Ethernet.
A
IEEE 802.9
18
Q
A standard that focuses on security issues by defining a standard method for protocols and services to exchange data securely by using encryption mechanisms.
A
IEEE 802.10
19
Q
The original IEEE
wireless standard, which defines
standards for wireless LAN communication.
A
IEEE 802.11
20
Q
A wireless networking standard operating in the 5GHz band. 802.11a supports a maximum theoretical data rate of 54Mbps. Depending on interference, 802.11a could have a range of 150 feet at the lowest speed setting. Higher-speed transmissions would see a lower range. 802.11a uses the CSMA/CA media access method and is incompatible with 802.11b and 802.11g.
A
IEEE 802.11a
21
Q
A commonly deployed IEEE wireless standard that uses the 2.4GHz RF range and offers speeds up to 11Mbps. Under ideal conditions, the transmission range can be as far as 75 meters.
A
IEEE 802.11b
22
Q
An IEEE wireless standard that is backward compatible with 802.11b. 802.11g offers a data rate of 54Mbps. Like 802.11b, 802.11g uses the 2.4GHz RF range
A
IEEE 802.11g
23
Q
The 802.11n standard significantly increase throughput in both the 2.4GHz and 5GHz frequency range. The baseline goal of the standard reaches speeds of 100Mbps, but given the right conditions, 802.11n speeds may reach 600Mbps. In practical operation, 802.11n speeds are much less.
A
IEEE 802.11n
