Session 3 : What is the network building block?

Network Building Blocks


The building blocks that are used to construct network are:
-Nodes
-The Network backbone
-Segments
-Subnets

Nodes
A node is any network device that can connect to the network and can generate, process, or transfer network data.
Network nodes can be either:
~Endpoints:  Nodes that function as the source or the destination of data.
~Redistribution points: Nodes that are devices used to transfer data, such as a network hub or router.




The Network Backbone
The network backbone is the highest-speed transmission path that carries the majority of the network data.




Segment
A segment is any discrete physical subdivision of a network.
A segment is bounded by physical internetworking devices such as hubs, switches, and routers.
Dividing a network into segments can make network performance more efficient.




Subnets 
A subnets is a portion of a network that shares a common network address.
