A network is a set of items, which in Graph Theory are called vertices (or sometimes nodes) with connections between them, called edges
- Social Networks: Patterns of friendships Facebook, LinkedIn
- Information Networks: Network of Citations
- Technological Networks: Electric Power Grids, Network of Airline Routes, Network of Roads, Railways etc
- Biological Networks: Metabolic Networks, Gene Regulatory Networks Ecological Networks (Food Web) Protein Contact Networks
Biochemical reactions can be represented in the form of Network. Each Metabolite is a node. Nodes are connected if they form substrate-product pair in a reaction. I reconstructed Metabolic Networks of 200 Bacterial species and compared their network topology using Graph Theoretical parameters such as Gaint Strong Component, Degree Distribution etc.
