100basefx Correct Ans - A 100BaseT variant that runs over fiber-optic
cabling. 100BaseFX is generally used for high-speed local area network (LAN)
backbones.
100baseT Correct Ans - Based on the standard from Institute of
Electrical and Electronic Engineers (IEEE) 802.3 Ethernet and uses twisted-
pair cabling, as does 10BaseT Ethernet. However, 100BaseT runs 10 times
faster than 10Base2 and 10Base5, at 100 megabits per second (Mbps).
10base2 Correct Ans - Also known as Thinnet, one of several physical
cabling standards from Institute of Electrical and Electronic Engineers (IEEE)
for IEEE 802.3 Ethernet networks. 10Base2 uses thin RG-58A/U coaxial
cabling for connecting nodes on a bus topology, as does 10Base5.
10base5 Correct Ans - also known as Thicknet, 10Base5 was the
original Ethernet cabling standard. It is called Thicknet because it uses a
coaxial cable approximately 0.4 inch thick.
10baseT Correct Ans - One of several physical cabling standards for
IEEE 802.3 Ethernet local area networks (LAN). 10BaseT networks use
twisted pair cabling for connecting nodes in a star topology.
address resolution protocol (ARP) Correct Ans - The protocol used by
transmission control protocol/Internet protocol (TCP/IP) for address
resolution. Address resolution refers to the ability of a station to resolve
another station's media access control (MAC) (hardware) address given its
Internet protocol (IP) address.
appletalk Correct Ans - Was Apple's proprietary, seven-layer, peer-to-
peer network communications protocol for Macintosh networks. AppleTalk
ran on Apple network topologies, as well as over Ethernet and Token Ring
networks.
, asynchronous transfer mode (ATM) Correct Ans - A cell-switching
network that consists of multiple ATM switches that forward each individual
cell to its final destination. ATM can provide transport services for audio, data,
and video.
Bootstrap Protocol (BOOTP) Correct Ans - Described in RFC (Request
for Comments) 951, is a method in which a diskless workstation or terminal
can obtain an Internet protocol (IP) address from a BOOTP server.
bridge Correct Ans - A hardware device that connects local area
networks (LAN). It can be used to connect LANs of the same type or LANs with
different types of medias. A bridge operates at the Data Link Layer (Layer 2)
of the Open Systems Interconnection reference model (OSI/RM).
bridge router (brouter) Correct Ans - A brouter is an internet working
device that combines the functions of both a bridge and a router. See router.
broadcast Correct Ans - The term broadcast is used in several different
ways in communications and networking. With respect to local area networks
(LAN), the term refers to information (that is, frames) sent to all devices on
the physical segment. For example, a bus topology, in which a common cable
is used to connect devices, is considered a broadcast technology. Another
common use of the term broadcast relates to frames. Broadcast frames
contain a special destination address that instructs all devices on the network
to process the frame.
checksum Correct Ans - s computed by the number of bits in a
transmitted unit of data. A checksum is appended to a data unit as a simple
error-detection method. The receiving node counts the data bits and
compares the result to the checksum to see whether all bits have arrived. If
the numbers match, the transmission was likely complete. Ethernet, Internet
protocol (IP), transmission control protocol (TCP) and user datagram protocol
(UDP) provide checksum count and verification.
collision Correct Ans - Occurs in an Ethernet network when two
frames are put onto the physical medium at the same time and overlap fully or
partially. When a collision occurs, the data on the physical segment is no
longer valid.
