Here you will learn network topology introduction, how computers get
connected, bus, star, hub, hybrid, mesh, tree topologies and network physical
design. In Computer Networking �topology� refers to the layout or design of the
connected devices. Network Topologies can be physical or logical. In this
section I will illustrate on the different types of the topologies.
Physical Topology means the physical design of a network including the
devices, location and cable installation.
Logical Topology refers to the fact that how data actually transfers in a
network as opposed to its design.
Topology can be considered as a virtual shape or structure of a network. This
shape actually does not correspond to the actual physical design of the devices
on the computer network. The computers on the home network can be arranged in a
circle shape but it does not necessarily mean that it presents a ring topology.
Topology refers to the way in which the network of computers is connected.
Each topology is suited to specific tasks and has its own advantages and
disadvantages.
The choice of topology is dependent upon
- type and number of equipment being used
- planned applications and rate of data transfers
- required response times
- cost
There are FOUR major competing topologies
Most networking software support all topologies.
