Various kinds of network topology on a computer
Topolgoi Bus
bus
In bus topology, both unjung network must
be terminated with a terminator. Barrel connector can be used to expand
it. Network consists of only one cable channel that uses a BNC cable.
Computers that want to connect to a network can link himself with mentap
Ethernetnya along the cable. Linear Bus: This layout includes the
general layout. The main cable connects each node, to a single channel
to access the computer with the tip end. Each node is connected to two
other nodes, except the engine at one end of the cable, which each node
is only connected to one another. This topology is often found in client
/ server system, where one of the machines on the network has
functioned as a File Server, which means that the machine is devoted
only to the distribution of data and not normally used for information
processing. Installation Bus network is very simple, inexpensive and
consist of a maximum of 5-7 computers. The difficulty often faced is the
possibility of collisions because the mechanism is relatively simple
network and if one node is broken then would disrupt the entire network
performance and traffic.
* Excellence is the development of a network bus topology or adding new
workstations can be done easily without disrupting the other
workstations. The drawback of this topology is when there is
interference along the center of the whole cable network will be
impaired.
Linear bus topology is a topology widely used in the mushrooming use of
Coaxial cable. By using the T-Connector (with a 50ohm terminator on the
end of the network), then the computer or other network devices can be
easily connected to each other. The main difficulty of using coaxial
cables is difficult to gauge whether the coaxial cable that is used
completely matched or not. Because if not truly be measured properly
will damage the NIC (network interface card) that is used and the
network performance becomes hampered, not reaching maximum capacity.
This topology is also frequently used in fiber optic network with a base
(which later merged with a star topology to connect with clients or
nodes.).

star
Star topology is a form of network topology in the form of convergence
of the central node to each node or user. Star network topology
including network topology with high costs.
Excess
* Damage to one channel will affect only the network on the channel and the station adrift.
* Security level is high.
* Resistant to a busy network traffic.
* Addition and subtraction station can be done easily.
Shortage
* If the node was destroyed, then the entire network will stop.

Topology Ring / The Ring

ring
Ring topology is a network topology where each point is connected to two
other points, forming a circular path to form a ring. In a ring
topology, data communication may be disrupted if a single point of
disorder. FDDI networks anticipate this weakness by sending data
clockwise and counter-clockwise simultaneously.

Mesh Topology

mesh
This network topology to implement fully the relationship between
central. The number of channels should be provided to form a mesh
network is a central number minus 1 (n-1, n = number of central). The
complexity of the network is proportional to the increasing number of
centrally mounted. Thus in addition to less economical also relatively
expensive to operate.

Tree Topology

tree
Network Topology Tree (Tree) network topology is referred to as
multilevel network topology. This topology is typically used for
interconnection between different central denganhirarki. For the lower
hierarchy depicted on the location of low and increasingly higher up the
hierarchy have. This type of network topology suitable for use on a
computer network system.
In the tree network, there are several levels of nodes (node). Central
or higher level node, another node can set a lower level. Data sent to
the central node in advance. For example to move from a computer with a
node-3 node kekomputer-7 as well as in the figure, the data must pass
through node-3, 5 and node-6 before ending at the node-7. Keungguluan
network tree model like this is, can the formation of a group that is
required at all times. For example, companies can form a group
consisting of terminal accounts, as well as on other groups formed for
the sale terminals. The drawback is, if the node is higher then does not
work, then another group who are below it eventually also became
ineffective. The workings of the tree network is relatively slow.

Linear Topology

linear
Computer network with a linear topology usually called a linear bus
topology, this layout includes the general layout. One main cable
connecting each connection point (computer) connected with a connector
called a T connector and the ends must be terminated with a terminator.
Connectors used type BNC (British Naval Connector), actually is the name
of the BNC connector instead of the name of the cord, the cable used is
RG 58 (Thinnet Coaxial Cable). Installation of a linear bus topology is
very simple and inexpensive, but most consist of 5-7 computers.
Connector type consists of
1. BNC cable connector -> To connect the cable to the T connector.
2. BNC T connector -> To connect the cable to the computer.
3. Barrel BNC connector -> To connect two BNC cables.
4. BNC Terminator -> To mark the end of the bus topology.
Advantages and disadvantages of computer networks with a linear bus topology is:
* Benefits, saving the cable, the cable layout is simple, easily
developed, does not need central control, and the addition or reduction
of the terminal can be done without disturbing the operation running.
* Losses, fault detection and isolation is very small, high-density
traffic, lack of data security is assured, the speed will decrease when
the number of users increases, and the required repeater for long
distance
