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 https://www.ccna.com.au/services/converged- networks /.

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.
