Computer network topology is a thing that explains the
geometric relationships between the basic elements of network components,
namely links, nodes and stations.
Computer Network Topology is also commonly called a way or
concept to connect several / many computers at once into a network that is
connected to each other.
Each computer network topology will have differences in
various aspects such as differences in the speed of data transmission, ease of
the maintenance process and manufacturing costs (many cables). And each type of
computer network topology also has advantages and disadvantages of each. for
that consult CCNA, which type of network is needed, you need to know about Converged Network, Network Infrastructure,
Wireless Networks, Network Applications, SIP etc. For more information visit

Ring Network Topology
Understanding ring topology is a computer network topology
where each node is connected to two other nodes (1 node is connected to 2
nodes), so it forms a circle (ring). Unlike the bus topology, the ring topology
(ring) has no end stopped. The signal travels around the loop in one direction
and passes through each computer which can act as a repeater to increase the
signal and send it to the next computer.
Bus Network Topology
Bus topology is a transmission method on a network that can
be described as a transmission that uses public buses. Therefore, the BUS
network is classified as joint communication. thus illustrates the bus network
topology.
But in the bus topology only one device is permitted to send
at one point in time. Distribution Access Protocol (DAP) has information about
the station that has to send data. The data that is transmitted has a frame
that will have a network address and source name.
Bus network installation is very simple, inexpensive but has
a maximum of 5-7 computers. There are several difficulties that are often faced
later, the possibility of data collisions because the network mechanism is
relatively simple and if one node is broken it will disrupt the performance and
traffic of the entire network. For that you need to use expert technology such
as CCNA.
Star Network Topology
This topology refers to networks where all nodes are
connected individually to one public hub. the transmission station star is
connected in such a way to a central node that is designed to resemble the
shape of a star. In star network types, data exchange can only be done indirectly
through the central node to all other nodes that are connected.
The essence of Star Topology (star) is a form of network, or
network layout where all devices revolve around a central hub. All computers in
star topology are connected to central devices such as routers, hubs, or
switches. Computers on a network are usually connected by a switch (hub) or
router with a shielded Twisted Pair (STP) cable or 1,527 Twisted Pair (UTP).
This star network topology is like we pull a cable from each
computer to the center of concentration such as a Hub / Switch. Hub (Switch)
will later handle Outgoing traffic to other nodes in a network.
