Network topology is a way to connect computers to each
other to form a network computer. In a computer network topology of the
selected type will affect the speed of communication.
1. STAR Topology
Characteristics of Star Topology
1. Each node communicates directly with each node
communicates directly with the concentrator (HUB) concentrator (HUB).
2. If each packet of data that goes into each data
packet When coming into consentrator (HUB) then broadcast throughout very much
connected nodes (eg using 32 port hub), performance (eg using 32 port hub),
then the performance of the network will be more dropped. network will be down.
3. Very easy to develop
4. If one ethernet card is broken, or one of the wires
on the terminal end, the network can still keseluruhhan keseluruhhan network
can still communicate or do not occur down to communicate or not happening down
on the overall network. the overall network.
Advantage Star Topology Star Topology Advantages
1. Pretty easy to change and add and add computers to
the network using a star topology without disrupting ongoing network aktvitas.
2. If one computer on the network is damaged then the
computer is not going to make the whole network star dies.
3. We can use several types of cable we can use several
types of cables in the same network with a hub that can accommodate different
cable types.
Losses Losses Star Topology Star Topology
1. Having a single point of error, lies in the hub. If
the central hub fails, the entire network will fail to operate.
2. Need more cable because all network cables to be
pulled to one central point, so more need more cable than other network
topologies.
3. The number of terminals is limited, depending on the
existing ports on the hub.
4. Heavy data traffic may cause the network to work more
slowly.
2. Topology BUS
BUS Topology Characteristics
1. Node - nodes are connected in series along the cable,
and on both ends of the cable along the cable close to the terminator.
2. Very simple in installation
3. Very economical in cost.
4. Data packets intersect each other at a cable.
5. Not required hub, which is much needed Tconnector on
each ethernet card.
6. The problem that often occurs is if one node is
damaged, then the whole network can be down, so that all nodes can not
communicate in the network.
BUS Topology Advantages
1. Save cables
2. Layout simple cable
3. Easily developed
Losses Topology BUS
when there is a disturbance in the center of the cable
along the whole network will crash.
3. Topology RING
RING topology characteristics
1. Node-Node-node connected in series along the cable,
the network shapes like circles.
2. Very simple in layout like the kind of bus topology.
3. Data packets can flow in one direction (left or
right) so that collisions can be avoided.
4. Faced the same problem with the bus topology, ie: if
one node is damaged then the whole node can not communicate with the network.
5. Type of cable used is usually cable or UTP Patch
Cable (IBM type 6).
Ring Topology Advantages
1. Data flow in one direction so that the collision can
be avoided.
2. Data streams flow faster because it can serve data
from the left or right of the server.
3. Can serve the traffic flow data intensive, because
data can be moved left or right.
4. Time to access data more optimally.
Losses Topology Ring
1. If there is one computer in the ring fails to
function, it will affect the entire network.
2. Increase or decrease the computer will mess up the
network.
3. It is difficult to reconfigure.
4. MESH Topology
Characteristics of Mesh Topology
1. Mesh topology has redundant connections between
existing equipment.
2. Arrangement at any existing equipment in the network
are connected to each other.
3. if the number of devices connected very much, of
course it will be very difficult to control compared to only a few devices are
connected.
Benefits Mesh Topology
1. The main advantage of using mesh topology is fault
tolerance.
2. Ensuring the communication channel capacity, because
it has excess connections.
3. Relatively easy to do troubleshoot.
Losses Mesh Topology
1. The difficulty at the time of installation and
reconfiguration when the number of computers and devices connected in
increasing numbers.
2. Costs to maintain a surplus.
