Hello steemians, I am very delighted to write my homework post for this week and also using this opportunity to say a very big thank you to prof @yousafharoonkhan for this wonderful lecture this week.

Question 1
Decentralization is the process by which the activities of an organization, particularly those Concerning planning and decision making, are delegated away from a central, authoritative location or group, in other words decentralization is talking away the power from the Supreme level and the state level and giving it to the local level.

Centralized exchanges involves intermediaries such as companies who act as middleman in order to facilitate trading on their platform in exchange for providing this service. Intermediaries collect trading fees

Centralization system

In a centralization system, all users are connected to a central network owner. The central owner store data for which other users can access to and also user information. Centralization is easy to set up and also can be developed quickly.
A centralized system is easy to set up and can be developed quickly.
But this system has an important limitation. If the server crashes, the system no longer works properly and users cannot access the data. Because a centralized system needs a central owner to connect all the other users and devices, the availability of the network turn on to this owner.

Decentralization systems

decentralized systems don’t have one central owner. Decentralization system use multiple central owners, each of which usually stores a copy of the resources users can access.
A decentralized system can be just as unsafe to crashes as a centralized one. However, it is design by more tolerant to faults. In other words, decentralized system generally has multiple authoritative nodes, each of which serves a subset of the total end users.

Question2

Centralization system in an organization involves decision-making in the hands of top management. It shows that all the power, authority is sustain at the topmost level whiles Decentralization system in the other hand is an organization involves decision-making capability through middle management or lower management.
So decision making in decentrilzation system is faster than that in centrilization system.

In terms of finance or cost, the cost is very high in decentralized system and low in centralized system. This is because everything is well planned and budgeted for before setting up and debated on should they be the need to spend more. But in the decentralized system, it is very expensive to set up since it involves settting up several servers.

Another difference is that decentralized system is more secured than centralized system. In the decentralized system, the user has all his passwords and the blockchain has not been hacked unlike in centralized system which has been hacked before. User data in centralized system is at risk because it can be edited by the owner but data in decentralized system cannot the edited or deleted.

Question 3

Advantages of Decentralized

1. Employees are empowered to make their own decisions that will benefit the organisation
2. It also results in a high level of employee satisfaction
3. Decision making is very fast
4. It also boots the productivity of an organization
5. Low-level employees to gain leadership skills which can contribute to the growth of the organization.

Disadvantages of Decentralized

1. The owner is responsible for the security : example, if you lost the keys of your steem blockchain, is not easy to recover it, also to restore the funds because the accounts has value.

2. Liquidity problem that’s is another disadvantage because they are not yet popular to everyone

3. Cost is very high since various servers are set up to ensure maximum security

4. Lack of coordination that’s, each department is given due powerings to delegate their operations adequately.

5. External factors; factors like market fluctuations, government policies and interventions etc.

Advantages of centralized system

1. There is less cost as compared to Decentralized system.
2. There is a change of command in the centralized system.
3. It allows employees to have a well-defined framework within which all work needs to carried out
4. More employees are employed to manage the system leading to employment opportunities.
5. There is a shared vision between the authority and the users.

Disadvantages of centralized system

1. It increases the time taken for decisions to come
2. It may result in biased decision making
3. Records are not accurate
4. The security is very weak and it easy for hackers to hack
5. Decisions making is very slow.

Question 4

Which one is better for Business/trading and why?

Per-by the research I did on decentralized and centralized, the one which is better for business depends on the type of business the user want to go into.
But comparing the two, Decentralized system is good for business and trading. These are the reasons why I choose decentralized system;
Employees are empowered to make their own decision that will benefit the organisation, Decision making is very fast also, decentralization improves motivation and creativity and it can also encourage teamwork and collaborative intelligence and last but not least it also boots the productivity of the organisation.

Question 5

Step1

Go to google page then type:
http://ether scan.io/

Step2

Paste company token contact address in the search book. For the purpose of this article we will use coinbase and click on search

Step3
Click on contract

Step4

Now check contract source code

In a source code if you see distract only administration, self distract in the cording area for this token. Then it indicates that the system is not completely centralized.
Since we didn’t find the above wordings in our coinbase code source then it means that coinbase is fully Decentralized.

In conclusion, decision making is very fast in Decentralizetion and also results in high level employees satisfaction.
I think of it will help expand business since no third party is involved. I therefore stand with decentralization.
Much thanks to @yousafharoonkhan
