Network topology
The topology of the network is defined by two types: the
physical topology and the logical topology. While the physical topology talks
more about the geometry and the physical location of the devices in the same
hand, the logical topology refers more to the way in which data communication
or signaling occurs between devices.
What is the network topology?
The topology of the network is the arrangement of the
different elements of the network, such as network links, computers, switches,
nodes, Wi-Fi hotspots, laptops and other network devices in a computer network.
There are two types of network topologies:
Physical network topology and,
Logical network topology
What is a physical topology?
A physical topology defines how all network devices are
physically connected in a computer network. It mostly defines the physical
connections between the devices.
What is a logical topology?
A logical topology defines the logical connectivity of
network devices in a computer network. Therefore, it can happen that devices
connected in a physical topology type have a different underlying logical
topology.
If we elaborate more on the physical topology, it is
essentially the location of the various components of the network in a
computer, such as the location of the devices, the connection between the
devices, the installation of the cables, etc. On the other hand, the logical
connection defines how data flows between devices.
For example, let's say there are five devices (A, B, C, D
and E) that are connected in a row. This configuration of network devices may
look more like a bus topology. But let's say that device A can directly
transmit the data to device E. That means that it looks more like a Circle that
logically is a ring topology, but a bus topology.
We will talk about different types of topologies, physical
and logical, one by one in the next article. If you want articles on a
