Network
Network Physical Topology
Mesh
device point-to-poin link to every other devices
advantage
less traffic, robust, secure
disadvantage
need more resource, expensive
Star
each device has a dedicated point-to-point link only to a central controller (hub)
Advantages
less expensive
robustness
easy to install and reconfigure
Disadvantage
single point of failure
Bus
multipoint topology
all devices are linked through a backbone cable
Advantage
Easy of installation
Disadvantage
difficult reconnection and fault isolation
broken of the bus cable stops all transmission
Ring
each device in the ring incorporates a repeater
signal is passed along the ring
Advantages
relatively easy to install and reconfigure
fault isolation is simplifed
Disadvantage
unidirectional traffic
Tree
integrate multiple topologies together
bus + star
advan
point to point wiring for individual segments.
disad
more difficult to configure
backbone line breaks, the entire segment goes down

sequence the transfer of packet
Types of Network Processing
Client/server computing
links two or more computers in arrangement
some machines, called servers provide computing server for user PCs
P2P
client/server distributed processing, which each computer acts as client an server: like torrent
Definition
set of devices (nodes)
connected by communication links
node
