INTRODUCTION
1.1 Background
Computer
technology is indispensable in helping to improve the performance of a company today. Year after year
people start using a computer that is currently known as the Personal Computer (PC). Originally Personal
Computer used by each person and stand
alone (stand alone). These
computers are not connected to
each other. But people then think that
data processing is a stand-alone in the sense
of a very slow and inefficient. For stand
alone PC, the application
program must be loaded
onto each PC, and the process must move
the PC. To improve
the efficiency and minimize the time required then created a network that is currently
known by the name of the
computer network.
This network is composed
by several methods
known to the network
topology. Some of which are known as the star of
a network or network
and many others.
To know more deeply,
the paper will
explain the types of network
topology, its flaws and how to
workarounds.
1.2 Purpose
Based on the above background, this paper aims to
find out about the
types of network
topologies and
their drawbacks and advantages.

DISCUSSION
2.1 Definition
and Types of Network
Topology
Network topology is a rule or a way to connect one computer to another computer so as to form a network. The network topology can also be defined as a physical picture of the pattern of relationships between network components, which include servers, workstations, Hubs, and cabling.
2.2 Here are the types of
network topologies:
2.2.1. BUS Topology
Bus topology is the initial topology is used to
connect a computer. In this topology each computer will be connected to a long
cable with multiple terminals, and at the end of Kable must end with a
terminator.
BUS Topology Characteristics:
1. Node - nodes are
connected in series along the cable, and the cable at both ends closed with a terminator.
2. Very simple to install.
3. Very economical in cost.
4. Data packets on a cable intersect each other.
5. Not required hub, which is much needed is Tconnector on each ethernet card.
6. Problem that often occurs is that if one node is damaged, then the whole network can be down, so that all nodes can not communicate in the network.
2. Very simple to install.
3. Very economical in cost.
4. Data packets on a cable intersect each other.
5. Not required hub, which is much needed is Tconnector on each ethernet card.
6. Problem that often occurs is that if one node is damaged, then the whole network can be down, so that all nodes can not communicate in the network.

Advantages of Bus Topology
|
1. Traffic
(traffic) would be very slow crowded
buses.
|
1. Simple topology.
|
2. Each barrel connector that is
used as the link weakens the electrical signal is sent, and most will block
the signal to be received correctly.
|
2.
The
cable used to connect a computer-bit computers or
other equipment.
|
3. It is very difficult to
troubleshoot on the bus.
|
3.
They
cost less
than other wiring arrangement.
|
4. Slower than the other
topologies.
|
4.
Quite easy if we want to expand the network on
a bus topology.

2.2.2. STAR Topology
Star topology is a network that
connects each node by using
a centralized interface or called concentrator.
Star topology network with an office in applications typically using an architecture host
based system.
Characteristics of Star
Topology:
1. Each node
communicates directly with the concentrator (HUB).
2. When each incoming data packet to consentrator (HUB) and then in broadcast throughout very much connected nodes (ex. use 32 port hub),
then the performance of the network will be down.
3. Very easily developed.
4. If one ethernet card is broken, or one of the wires in the terminals broke up, then to the overall network can still communicate or do not happen down the entire network.
5. Type of cable used is usually the type of UTP.

2.2.3. RING Topology
Ring Topology is a network topology
form a series of dots , each of which is connected to two other points , so as
to form a circular path to form a ring .
In a ring topology , each point / node serves as a repeater which will amplify the signal along the circulation , meaning that each device work together to receive a signal from the device before then pass them on to the device afterwards , the process of receiving and forwarding the data signal is aided by TOKEN.
In a ring topology , each point / node serves as a repeater which will amplify the signal along the circulation , meaning that each device work together to receive a signal from the device before then pass them on to the device afterwards , the process of receiving and forwarding the data signal is aided by TOKEN.
TOKEN contains information along with the data from the source computer , then the token will pass through the point / node and will check whether the data is used by the information point / node in question , if yes then the token will provide the data requested by the node and then re-run to point / next node in the network . If not then the token will pass through the point / node while bringing the data to get to the point / the next node . This process continues until the data signal peak at the goal ./ the next node. This process continues until the data signal peak at the goal.
Or Ring topologies are used in a network topology
that has high
performance, network bandwidth for time-sensitive features such
as video and audio, or when performance is needed when
the computer is connected to the
network in large numbers.
Characteristics
of
Ring Topology:
1. The nodes
are connected in series along the
cable, the network
forms like circles.
2. Very simple in layout such as the type of bus topology.
3. Data packets can flow in one direction (left or to the right) so that collisions can be avoided.
4. Faced the same problem with the bus topology, ie: if one node is damaged then the entire node can not communicate in the network

4. Faced the same problem with the bus topology, ie: if one node is damaged then the entire node can not communicate in the network
5. Type of
cable used is usually cable
or UTP Patch
Cable (IBM type 6).

Advantages of Ring Topology
|
|
1. Data
flows in one direction so that the collision
can be avoided.
|
|
2. The data stream flows faster because it can serve
data from the left or right
of the server.
|
|
3. Can
serve the traffic flow data is solid,
because data can be moved left or right.

2.2.4 TREE Topology / Topology HIERARCHICAL TREE
TREE Topology / Topology HIERARCHICAL TREE is also referred to as multilevel
network topology, used for interconnection of central with different arrangements. Tree topology is the development of a star topology. At
each Tingkai Tree
topology or node
will be attributable to the central or
concentrator (Hub or Switch) is located
at the beginning of Trafic series.
Characteristics
of Tree Topology :
1. Characteristics of the
tree topology similar to BUS Topology and
Star Topology. So
also with appliances, wires, and installation
techniques.Therefore we will not discuss it in
more detail. If the inter-hub connecting cable broke,
the star network
can still function, only the relationship with the
other tissues will be
disrupted star.
2. At each branch connected to several terminals
in the form of bus or branched again to be complicated.
3. Starting from a point called the
head-end. From the head-end cable is
pulled into
several branches.

2. Connections happen point to point.
|
|
3. Easy management for easy
identification and isolation of faults in
the network.
|
|
4. Easily developed.
|
|
5.
This topology is fairly effective on a smaller area, where the central computer can be connected to different other computer, and
other computers can provide a connection
to the computer at the center they
serve.

2.2.5 Loop topology
Loop topology is the topology
in which the relationship between a serial terminal
in the form of a closed
loop and no one becomes the central terminal.
Loop Topology Characteristics :
1. Is a
cable that both ends are closed, where there are nodes along the cable.
2. Commonly used because it is simple in installation.
3. Signal cables pass through in both directions and possible collision.
4. The biggest problem when the cable broke. If one segment of cable broken, then the whole network is interrupted.

3.1 Conclusions
Network topology is, things that
describe the geometric relationship between the basic elements making up the network
are nodes, links and station.
In the definition of topology is divided into two, namely the physical topology (physical topology), which indicates the position of the physical cabling and topology logical (logical topology) that shows how a medium accessible by the host.
In a comparison between all the topologies that have been described previously, the most well-used topology is the star topology because if one computer is down does not affect the others and the tracking error is very fast and access to other computers more quickly and easily upgraded.
