First of all I would like to congratulate you as a new professor. Also thanks for this beautiful Home work Task. I am happy to participate in your Homework Task.
This week Homework Task is about Centralized and decentralized network.

Centralized & Decentralized

source

• Centralized
  In central systems, a single author who control the hole networks. No one can Intervention in this system. Author control all the system, managing the data and permission. Central Author cam make his decision on his own. Bank is the example of central systems. Like Bank author control the hole system. Your account and your money is fully control by bank.
  Social media and search engine also the example of centralized network.

• Decentralized
  Decentralized system organized and distribute data, information , workload across in the network connected servers . Network has separate authority and they can make decision independently

Difference between Decentralization and Centralization system

In the Centralization system, user can not control anything. User account and money are control by Central Author and can't make decision. Whereas, User can control his money in the Decentralized system. The decision can take independently.

User needs documents, confirmations in the central systems. Such as, when you open an bank account you need your documents and other information. On the other hand, in decentralized exchanges you can run without any procedures.

In Centralized system, The single author control the data and managing the data. He can delete or remove the data if he want. However, on the decentralized exchange, Network are connected with different servers. Data are connected with other servers at a time. So it's impossible to delete data.

Decentralized system hard to use but the reliability is high. While it is easy to use in Centralized system but this reliability is very low.

Advantages and Disadvantages of decentralized and centralized system.

Advantages of Decentralized System

• Data keep safe and transfer speed are very fast. The chance are scalability very low.
• Decentralized System provide high security. So it is impossible to hack.
• there are no third party need to access so the transfer are transparency
• User can control and access their fund.
• reliability is high and There is no possibility of data failure.

Disadvantages of Decentralized System

• It's require more more computers and machines to connects with server.
• It is not to use easily.
• User are responsible for their security. It's impossible to recover if user loss their passwords.
• Sometimes there are problems faced when user wants to transfer the money.
• Decentralized System is not so popular.

Advantages of Centralized System.

• Easy to use.
• You can recover your password if you forget it. So you can recover your funds.
• defrauded rate is very law. Because they will keep user's information.
• Centralized System is so popular than Decentralized System.
• Transfer your money easily.

Disadvantages of Centralized System.

• Security is not so good. high hacking rate.
• Transfer fee is very high.
• it's control by single author . So you can not control your fund.
• Data can easily edited and deleted

Which one is better for Business/trading and why?

We already know about the advantages and disadvantages of decentralized and centralized system. For some cases both are good. However, overall for Business or trading Decentralized System is better than Centralized System. The benefits of Decentralized System is, you can check your ability and you can make your own decision. You can also plan how to make your business grow fast. In Decentralized System the decision they take will favorable to the users.

blockchain is decentralized or not?

It is easy to understand to check any blockchain is decentralized or not. 0X blockchain i choice to check. First i go to this sitecoin market

Then i click explorer and click the first option name etherscan.Io then i click this link

When i click here i see this interface. then i click contract address and find this code. Here i can easily find and understand this 0x is a decentralized project.

Conclusion

Thanks to professor @yousafharoonkhan for your lecture. I know many things about decentralized and centralized system.
