Definition Of Network Topologies

What is Network Topologies?

Definition

Network topologies can be defined as structures of a computer network. It is normally refers to how the nodes or computer are connecting and working together within the network to do the data transferring task.

Brief history of network topologies

The sharing of data and information is way more difficult in the early 1960s compared to the sharing system nowadays because each of the computers was physically shared. The researcher had come out with a solution to solve the problem, thus, the computer network was invented. Packet switching, which was the new interaction protocol, had made a big alteration that made the secure voice transmission in military channels became possible. Gently, in the wake of the era transformation, this interaction protocol has become the foundation of the machine to machine communication technologies. Also, it was imposed to the computer networks after some precision.

Examples of Network Topologies

Network topologies can be classified in to four types. For instant, star topology, ring topology, bus topology and mesh topology.

Star Topology

Ring Topology

Bus Topology

Mesh Topology

Among all the network topologies, Star topology is the main topic that will be discussed in the following report.

What is Star Topology?

Definition

Star topology is a network topology which all the nodes are individually connected to a central conduit to do the data transmission.

Description

Star topology is one of the most commonly use network topologies in the market. With the foundation in the switching system of the telephone, it is also known as the most ancient data exchange design method. Each of the nodes connected to the central conduit directly to do the dat...

...y, which all nodes are connection is to a main node that act as the backbone. There are two terminators at both of the end of the main nodes to absorb and clean up the signal. Once the backbone is down, the while network will be unusable too. Star-wired bus topology is another hybrid topology with the combination of bus topology and star topology. All the nodes are basically star-wired, connecting to the central device and uses the single bus data transmission method. Star-wired bus topology has longer distances coverage compared to the standard star or bus topologies. It can be used to interconnect different network segments. One of the disadvantages of using this topology is star-wired bus topology needs more cables and hubs or switches which will cause a bomb to the star-up cost. Modern Ethernet and fast Ethernet are set up base on the star-wired bus topology.
