Hey all welcome back to my homework series of crypto school 😃. Today am here in this blog going to do a homework for the professor @yousafharoonkhan. Thank you professor for the beautiful lesson. So let's get started ...

Understanding of centralized and decentralised network is an essential part in crypto currency. I feel it is necessary to know everyone about the advantages and disadvantages of Centralized and decentralised network.

Centralised network

---

• The term center defines all. We all should need to depend on the authorised central one for each and every aspects.

• In centralised network everyone should need to follow the orders in hierarchical structure. One should need to depend one another.

• At a top of the network there is only one authorised group or a person you can raise him a question or he can able to change the data of network.

Decentralised network

---

• Decentralised networks are not a single server it is a combination of multiple nodes.

• Decentralised network has many advantages of centralized networking. Especially data can't be handled by a single person.

• Decentralised network is inverse of centralised network it is not functioning on hierarchical manner.

Comparison between Centralised network and Decentralised network

Authorities:-

In centralised network, it runs on hierarchical structure so there is a sequential order of process. If error occurred mean we can able to raise a question and get an appropriate answer for the the raised questions. But in decentralised network we have no certain central authority. These network run by multiple nodes we can't able to get an appropriate answer in this case I felt centralised network is helpful over decentralised network.

Data security:-

In centralised network the data are stored in the single server hence it can be changed by the appropriate authorities or powerful firewall breaking Technics. It can also be get erased by physical natural factors like wind water and fire. In decentralised network node are running on different many nodes hence data can be retrieved. In this case we find an advantage of decentralised network.

Governance

In Centralised network governance run by a single head authority hence the chain-link will not work completely in active participation but in decentralised network all the participants are a main members hence they involve actively.
