yes, network topology does matter to design a network. as we know that topology is a structure of network. without a topology network cannot be designed. we have to consider which topology to use and what does each topology does. different topology have its different features. if you want most secure connection use full mesh topology
The internet uses a very complex topology, due to the massive number of nodes and the high redundancy that is characteristic of high availability systems like the internet. Different parts of the internet look like different topologies. The internet would be best approximated as a mesh topology. For an image of a simple mesh topology, and a discussion of the different possible network topologies, see the wikipedia article in the links below.
Network topology is the arrangement of the various components that make up the structure of a computer network. Network topology may be depicted in a physical or logical manner.
A ring topology graph will normally indicate the details of a network's structure. In a ring topology graph, information on individual machines will be shown and indicated. This information will include a Media Access Control address, as well as the Internet Protocol address for a network communicating device. Ring topology graphs are meant for understanding the layout of any given network design.
Any topology can be used for a peer-to-peer network. The easiest is probably a star topology but it doesn't have to be.
Star Topology.
network topology
tpology are mainly three types (1) STAR TOPOLOGY,(2)BUS TOPOLOGY,(3)RING TOPOLOGY
Group of devices connected together forms a Network & structure (design) in which they interconnect is called Topology.
Star Topology
The most common LAN topology is that of a "star." In a star topology, each computer, or "node", is connected to a central hub. This is more reliable than a more classical "ring" topology, because a node failing will not bring down the entire network. A bus topology is arguably more reliable, but has poorer performance.
