Test With Complete Solutions
Mesh Topology CORRECT ANSWERS Every node is connected to every other node.
Advantages: Reliable, Fault tolerant, No Traffic
Disadvantages: Expensive
Star Topology CORRECT ANSWERS All nodes are connected to a central hub.
Advantages: Scale-able
Disadvantages: Hub goes down, all computers go down.
Bus Topology CORRECT ANSWERS One main backbone all computers are connected
to.
Advantages: Easy Install
Disadvantages: Traffic, Difficult to find problem areas.
Ring Topology CORRECT ANSWERS Computers are connected on a loop or ring. Data
flows in one direction only.
Advantages: Easy/ Inexpensive
Disadvantages: If one computer goes down they all do
Hybrid Topology CORRECT ANSWERS Combining multiple typologies into one
network
Disadvantages: Fault detection, High Maintenance costs
PAN CORRECT ANSWERS Personal Area Network
good for one house hold and all of its connected devices
LAN CORRECT ANSWERS Local Area Network
Covers a relatively small geographic area such as a building
MAN CORRECT ANSWERS Metropolitan Area Network
, Covers a larger geographic area such Collage Campus
Sometimes called Campus Area Network (CAN)

Short CORRECT ANSWERS -32768 to 32767 (5 places)
Used for image processing
Napier's Bones CORRECT ANSWERS A set of rectangular rods with numbers etched
on them that let users do multiplication by adding the numbers on properly positioned
rods. Precursor to the slide rule.
Schickard's Calculator CORRECT ANSWERS An early mechanical calculator consisting
of a series of gears and spokes representing numerical values.
Babbage CORRECT ANSWERS Analytical Engine & Difference Engine (only
theoretical)
Hollerith CORRECT ANSWERS Invented a machine for tabulating and sorting punched
cards; the first automatic data processing system; utilized for the 1890 census.
UNIVAC CORRECT ANSWERS First commercially viable computer. Stored data on
magnetic tape.
