Peer-to-peer networking software - ANSWER -is included with most popular
desktop OSs. Each individual user configures software settings to allow or
disallow the sharing of that computer's resources by other users. There is no central
authority that decides what users may have access to what resources.
A network OS (NOS) - ANSWER -also called a client/server OS, provides
centralized control of all network resources. A network administrator can decide
what each user may see and do on the network. By far, the most common NOS
packages are Microsoft and UNIX/Linux servers.
Which of the following is managed by the OS? - ANSWER -Keyboard input
Screen display
File I/O
Peripheral control
The primary purpose of a device driver is to control hardware under the
supervision of the OS. True or False? - ANSWER -True
Most LANs - ANSWER -use star bus topologies.
Personal Area Networks (PAN) - ANSWER -are small and local. PANs connect
by means of Bluetooth wireless and can connect phones, tablets, mice, keyboards,
and more.
Local Area Networks (LAN) - ANSWER -can range from a few nodes in a home
office, to several hundred nodes in a corporation. However, a LAN is typically
confined to a single building.
,Campus Area networks (CAN) - ANSWER -consist of LANs connected across
multiple buildings, using transmission links owned by the company that owns the
network.
Metropolitan Area Networks (MAN) - ANSWER -are formed by connecting
LANs in several locations across a city or small region. The links between LANs
are typically leased from companies that provide telephony and data services.
Wide Area Networks (WAN) - ANSWER -are essentially the same as MANs, but
span longer distances. A WAN may include sites in the same country or multiple
countries.
Global Area Networks (GAN) - ANSWER -are designed to allow users to have
unlimited uninterrupted network access anywhere around the globe via LAN,
wireless, cellular, and satellite connections.
Which of the following network topologies forms a closed loop? - ANSWER -
Ring topology
Which of the following network topologies connects devices to a shared straight-
line cable? - ANSWER -Bus topology
Twisted pair - ANSWER -is the most common type of copper cable used in
networks.
There are two major ways to limit noise and crosstalk in a cable design: -
ANSWER -Shielding
Cancellation
Coaxial Ethernet networks must obey the "5/4/3 rule:" - ANSWER -Up to five
segments can be connected in a series between transmitter and receiver.
Up to four signal-repeating devices (repeaters, hubs, bridges, or switches) may be
used to connect segments.
A maximum of only three segments can contain Ethernet nodes.
, Coaxial Cabling Characteristics Bandwidth - ANSWER -Broadband coaxial
systems, such as Internet access via cable modems, offer high bandwidth because a
single cable can carry multiple baseband channels.
Coaxial Cabling Characteristics Noise Immunity - ANSWER -The shielding layer
of coaxial cable provides good resistance to electromagnetic interference (EMI)
and radio frequency interference (RFI). The outer braided shield effectively
conducts all outside electrical signals to the ground, protecting the signal on the
inner conductor.
Coaxial Cabling Characteristics Physical Installation - ANSWER -Coaxial cable
is bulky and relatively difficult to install through wire ducts and other spaces
within a building. In addition, a cable break anywhere along a bus can disable the
entire network segment.
Coaxial Cabling Characteristics Security - ANSWER -It is difficult to tap or
intercept a signal on a coaxial cabling system without detection. Any attempt to tap
into the coaxial bus will break or interrupt network traffic.
UTP - ANSWER -is the most popular LAN cabling because it is inexpensive,
light, flexible, and easy to install.
Twisted Pair Cabling Characteristics Bandwidth - ANSWER -As with many other
media, the bandwidth and distance of twisted pairs are interrelated. As the length
of a segment increases, its data rate decreases. The higher the bit rate, the shorter
the span.
Twisted Pair Cabling Characteristics Noise Immunity - ANSWER -Twisted pairs
provide the least immunity to noise of all physical conductors; the twisting
reduces, but does not eliminate, interference. The medium both emits and is
sensitive to EMI and RFI.
Twisted Pair Cabling Characteristics Security - ANSWER -Twisted pair is the
least secure of the common LAN media types. The cable radiates signals, which an
