2. Understanding , a varietyof computernetwork topology ~ We have had
many users device topology network computers, particularly in offices
and so on. Its use is helping to facilitate the access of the data to the
server simultaneously. This is the main reason for the formation of
the computer network topology. And along with the development of
the network is also developing a variety of network topologies that
computer.

3. Understanding the network topology is a technique
to connect one computer to another computer
that assemble into a network, where the network
topology is based on the use of cost, speed of
data access, the size and the level of connectivity
that will affect the quality and efiensi a
network. There are various kinds of network
topology many computers in use today include
Bus Topology, Ring Topology, Star Topology,
Mesh Topology, Linear Topology, each of these
topology types have their own advantages and
the minuts

5. This type of bus topology
uses a single cable, the
entire computer is directly
interconnected using only
one cable. Cable that
connects this network is
using coaxial cables and
attached to the T-
Connector.
1 .Topology Bus
To maximize the use of this network should use
the Fiber Optic cable for stability of resistance
that can transmit the data better.

6. Excess Bus Topology:
1. Easy to be developed
2. Does not require a lot of cable
3. Save the cost of installation of a
bus topology Weaknesses:
Unstable, if one computer is
interrupted then the network will
be disrupted
Error detection rate is very small
Difficult to find interference on
the network

7. This type of ring topology,
all computers are
connected together to
form a circle (ring)
covered and assisted by
token, token contains
information derived from
the source computer will
check whether the
information is used by
the point in question,
if there is then the token will provide data that
requested by the network point and headed to the
next point.

8. all of the computers will receive any signal
flowing information, the information will be
accepted if it is in conformity with the
address, and the signal will be ignored if
the information is not the address itself.
In other words, this process will continue
until the data signal is received at the
destination. Advantages:
1. Do not use a lot of wiring
2.Installation of a low level of complexity
3. Easy installation
4. Not going to happen hit the data

9. 5. Easily designed Disadvantages:
1. sensitive network error
2. Difficult to develop
3. If one point disrupted the entire network of data
communications can be disrupted

10. On the type of star topology, each computer is
directly connected using a hub, where the
function of this Hub is a traffic control all
computers connected.Because it uses the
process of sending and receiving information
directly is what causes the installation costs

11. Advantages: 1. Error detection is performed
2. Change the station easy to do and does not
interfere with other networks
3. Easily control
4. High security level
5. The most flexibleDisadvantages:
Using a lot of wiring
There is a possibility of data collision will
occur which can result in slow network
Network is dependent upon the central
terminal
High network costs
If the computer is the center point of the

12. This tree topology
is a result of the
development of
the star topology
and bus topology
consists of a
collection of star
topology and bus
topology
associated with
1. Tree topology is usually referred to
as the network topology and used
multilevel interconnection between

13. topology of this tree has the same strengths and
weaknesses with a star topology, among others: Pros:
1. Error detection is performed
2 . Changes in the shape of a group is easy to do and
does not interfere with other networks
At this network has several levels with a
specified node hierarchy, the picture is the
higher the position, the higher its
hierarchy. Each node that has a high position
who has a node can set a low position. Data sent
from the central node and then move towards a
low node and leading to higher node first.

14. 3.Easily control Disadvantages:
Using a lot of wiring
Frequent collisions
If the node is higher then the damaged
lower node will be interrupted too
How it works slow

15. Mesh topology is a
series of
interconnected
networks where
each device
absolutely
computers will be
connected directly
to any point other
devices. Each point
has a point that

16. Advantages:
1. Dynamic point in repairing any damage to
computer networks
2. The data is sent directly to the destination
without having to go through another computer
3. The data faster data transmission process

17. 4. If there is damage to one of the
computers will not interfere with other
computer Disadvantages:
The cost to set it up so big.
Need a lot of cable
It should be a lot of I / O ports, each
computer is required n-1 I / O port
and as many as n (n-1) / 2
connections. For example, there are 4
computers will require a cable
connection 4 (4-1) / 2 = 6 cable and
requires 4-1 = 3 ports.

18. This is an extension
of the topology of
a bus topology in
which the main
cables should be
connected to a
computer each
point using the T-
connector. The
topology of this

19. Advantages:
1. Simple network
2. Save the cable
3. Easily expandable Disadvantages:
1. Detection of very small mistakes
2. Safety not guaranteed
3. High data traffic
4. The transfer speed depends on the
number of users, speed down if the
number of users increases That
article understanding of a variety of
computer network topology , hopefully
can provide benefits, greetings
