HANDS-ON NETWORKING
FUNDAMENTALS FINAL EXAM Q&A
Internet Connection Sharing (ICS) - Answer-An option offered on Windows computers
that enables one computer connected to the Internet to share its Internet connection
with other computers on the same network. This can be a good Internet access solution
in a home or small office.
iOS - Answer-An operating system developed by Apple for mobile devices such as the
iPhone. Like Apple's Mac OS X for desktop and laptop computers, iOS is based on
Darwin UNIX and incorporates concepts from Mac OS X.
Local Area Network (LAN) - Answer-A series of interconnected computers, printing
devices, and other computer equipment that share hardware and software resources.
The service area usually is limited to a given office area, floor, or building.
Mesh Topology - Answer-A network design in which every node is connected to every
other node, achieving fault tolerance.
Metropolitan Area Network (MAN) - Answer-A network that links multiple LANs in a
large city or metropolitan region.
Network Interface Card (NIC) - Answer-An adapter board or USB device designed to
connect a workstation, server, or other network device to a network medium.
Node - Answer-Any device connected to a network, such as a personal computer,
tablet, mainframe, server, network equipment, or printer. Also called a station.
Open Handset Alliance (OHA) - Answer-An alliance of vendors such as google,
Motorola, Intel, Dell, and T-Mobile that has provided backing for the Android operating
system.
Peer-to-Peer Network - Answer-A network on which any computer can communicate
with other networked computers on an equal (peer) basis without going through an
intermediary, such as a server. _____________ networking enables each computer to
offer and access shared resources, such as files and printers.
Personal Area Network (PAN) - Answer-A network that typically reaches a few meters,
such as up to 10 meters (33 feet, even though some can reach further, and consists of
personal devices such as mobile computers, smartphones, and handheld devices. Can
be wired or wireless.
Private Network - Answer-A network owned and maintained by an organization, such as
a campus network operated by a college.
,Protocol - Answer-Similar to a language, a ______ enables network devices to
communicate and exchange information or data. A _______ is an established guideline
that specifies how networked data is formatted into a packet or a frame, how it is
transmitted, and how it is interpreted at the receiving end.
Public Network - Answer-A network that offers services to members of the public, such
as network services offered by a telecommunications company or a cable TV company.
Ring Topology - Answer-A network design consisting of a continuous path for data with
no logical beginning or ending point, and thus no terminators.
Server - Answer-A computer that provides extensive multi-user access to network
resources, such as shared files, shared disks, and shared printers.
Star-Bus Hybrid Topology - Answer-Also called the star-wired bus topology, a network
design that combines the logical communications of a bus with the physical layout of a
star.
Star-Ring Hybrid Topology - Answer-Also called the star-wired ring topology, a networks
design in with the logical communications are in a ring but the physical layout of the
network is a star.
Star Topology - Answer-The oldest type of network design, this topology consists of
multiple nodes attached to a central hub or switch.
Terminator - Answer-A resistor that is connected to the end of a segment on a bus
network, so that data-carrying signals are absorbed at the point where the segment
stops. Absorbing the signals ensures that they are nit reflected back onto the cable after
they reach the end---thus preventing communication errors.
Topology - Answer-The physical layout of cable and wireless network devices and the
logical path followed by network frames or packets sent on the cable or by wireless
transmissions.
Tree Topology - Answer-(Expanded Star Topology) Offers features of the basic bus
topology combined with features of the star topology. This topology resembles a tree
with a trunk and limbs or represents a root node at the base in a hierarchy of nodes built
on levels off of the root node.
Universal Serial Bus (USB) - Answer-A serial bus, such as in a computer, designed to
support up to 127 discrete devices with data transfer speeds up to 5 Gbits/s (gigabits
per seconds).
, Virtual Private Network (VPN) - Answer-A private network that functions like a tunnel
through a larger network---such as the Internet of an enterprise network---that is
restricted to designated member clients only.
Wide Area Network (WAN) - Answer-A far-reaching system of networks that usually
expands over more than about 48 kilometers or 30 miles and often reaches across
states and continents.
Workstation - Answer-A computer that has its own CPU and may be used as a stand-
alone computer for word processing, spreadsheet creation, or other software
applications. It also may be used to access another computer such as a server via a
network.
Analog - Answer-A type of transmission that can very continuously, as in a wave pattern
with positive and negative voltage levels.
Beaconing - Answer-An error condition on a token ring network at indicates one or more
nodes are not functioning.
Cyclic Redundancy Check (CRC) - Answer-An error detection method that calculates a
value for the total size of the information fields contained in a frame. The value is
inserted near the end of the frame by the Data Link layer on the sending node and
checked by the Data Link layer on the receiving node to determine if a transmission
error has occurred.
Full-Duplex - Answer-The capacity to send and receive signals at the same time on the
same medium.
Half-Duplex - Answer-The ability to send or receive signals on a medium, but not at the
same time
Primitive - Answer-A command used to transfer information from one layer in the OSI
stack to another layer.
Synchronous Communications - Answer-Communications of continuous bursts of data
controlled by a clock signal that starts each burst.
Token Ring - Answer-An access method developed by IBM in the 1970s and which is
still used on some networks. Variations of the technology are used for WANs. This
transport method employs a physical star topology along with the logic of a ring
topology. Although each node is connected to a central hub, the frame travels from
node to node as though there were no starting or end point.
Trunk Line - Answer-A main telecommunications link such as a phone line directly
connecting exchanges or switchboards at a considerable distance apart
