Cards in this deck (21)
- 1LANLocal Area Network
Network in a single building or
several buildings. - 2WANWide Area Network
For all to access the same data source. - 3MANMetro Area Network
it's coverage is between a LAN and WAN - 4PANPersonal Area Network
set up privately for a few people to
connect a small number of
devices together. - 5Physical TopologyThe physical layout of devices
on a network and how the
cables and wires connect
these devices. - 6Logical TopolgyHow data is transmitted
and received between devices
on a network regardless of
their physical connections. - 7TopolgyThe way in which the devices
(nodes) are connected. - 8NodeA device that is connected to
the network - 9Example of nodesComputers, printers, hubs,
switches and routers - 10Physical Bus TopolgyAll nodes are connected to
a single backbone. The
backbone is a single wire that
carries data packets to the nodes.
Terminators must be installed at the
two ends of the backbones. - 11Advantages of Bus TopologiesLess cable required than in other
typologies. - 12Disadvantages of Bus TopologiesUnable to accommodate a large number
of nodes-such as those required for
LAN's a single break in the backbone
disables the entire network. - 13Physical Ring TopologyEach node connects to exactly two
other nodes, forming a complete
ring, which generally circulates
data packets in one direction. Each
node receives data from one node
and transmits to the other. - 14Advantages of Ring TopologiesThere are dirty jokes that can be
made about it... if you're feeling
particularly inventive. Its a two way. - 15Disadvantages of Ring TopologiesIf one cable is broken the entire
network is disabled
to remove or add a node, the
entire network must be stopped
all nodes must be powered
at all times if the network is to
operate. - 16Mesh TopologiesThese include more than one physical
path between pairs of nodes.
Routers are required for mesh
typologies. - 17Advantages of Mesh TopologiesFault tolerance, as packages are
automatically routed around faults.
Can be used in high-speed long distance
connections. - 18Disadvantges of Mesh Topologies.Routers are required to direct each
data packet. - 19Physical Star TopologyAll nodes connect to a central
node via their own dedicated cable. The
central node is the device that connects
all outlying nodes such that they can
transmit and receive packets to
and from each other node. - 20Advantages of Star TopologiesEach node had its own cable and
can be connected and disconnected
without affecting any nodes.
New nodes can be easily added without
first disabling the network.
The process of identifying faults is
made more simple. - 21Disadvantages of Star TopologiesA lot of cabling is required. If a fault
occurs in the central node
then all connected nodes are
also disabled.
