DEFINITION OF THE DECENTRALIZED SYSTEM

It is an information system of interconnectivity,where no single person has the sole or ultimate authority.In respect to the concept of info technology and computing, decentralized systems is one that takes the form of networked computers. For instance, the Internet is a decentralized system, although in recent years it is fast becoming highly centralized. The decentralization system can also be seen as an open-source software applications that functions on a peer to peer connection of network, without the use of a central server.

THE DEFINITION OF A CENTRALIZED SYSTEM

A centralized system can be described as system were all users are interconnected to a central network owner or server. The central owner keeps and store data,that other users or clients can make use of or access, including user information system

This user information sometimes include user_ generated content, user profile, and more. A centralized system is very easy to construct or set up and can be developed quickly in little or no time.it could also viewed as an applications software that possesses different client nodes running, functioning, and controlled on a central client-server which is the direct opposite of the decentralized system.

COMPARISON BETWEEN A CENTRALIZED AND A DECENTRALIZED SYSTEM

1This two systems are the direct opposite of each other,in the sense that the Centralized systems are systems that function or make use of the client/server framework, a situation allows one or more client nodes to be directly connected to a central server. The implications of this means that it is controlled by a single entity who decides the fate of the rest based on the authority he owns, while on the other hand in the decentralized, every node creates its own decision. The ultimate behavior of the system is the totality of the decisions made by each individual nodes collectively. Unlike the centralized system,here there is no single entity or authority that collects and responds to the request.

2Decentralized systems can be runned anonymously without you knowing the person involved, and it can be funded and runned,that is, you can run your business and fund it by using a decentralized blockchain without even knowing each other or perhaps yourself, While in a centralized system the client has to identify himself before he or she can enter the system which is done only with the permission of a higher authority.

3Another disparity is that in a centralized system operators can shut down their network when they want and the user may be highly affected, While a decentralized blockchain, if in reality it is truly decentralized, can do no harm that means,it has no tendency to affect its clients.

4It is easier to use a Centralized system than a decentralized system as a decentralized system is not easy to use.

   ***  ADVANTAGES OF A CENTRALIZED SYSTEM***

1THEY ARE EASY TO PHYSICALLY SECURE.
It is easy to secure and maintain the server and client nodes by the reasonor virtue of their location

2It provides one with a Smooth and real personal experiences

3More cost effective for small systems Due to the fact that the central systems take less funds to structure or set up, they possess an edge when it comes to building a small system.

4There is a high possibility of a quick updates this is because there is Only one machine to update.

5It is easy to detach a node from the system.
By removing the connection of the client node out of the server the Node is automatically detached just like that

DISADVANTAGES OF CENTRALIZED SYSTEM

1 The centralized security system over the years have been proven to be weak giving room for hackers to have a fun filled day or roller coaster whenever it comes to hacking.

2The centralized system as the name implies is dictatorial in nature as it does not give room for lower level user to contribute in the decision making process which initiates a atmosphere of unhappiness and frustration.

3 It has also been pointed out that not all users are treated fairly and equally in this system, due to the fact that the system functions under an authority,

4Highly dependent on the whole network connectivity which implies that in an eventuality where the nodes lose it's connectivity the system can fail as there is only one central node present.

5No degradation of system , a situation where an abrupt failure of the entire system will result to a reduced possibility of data backup and so If the server node fails there is no possibility of backup, which leads to lose of data.

ADVANTAGE OF DECENTRALIZED SYSTEM

1It softens or reduces the work load on top executive

2It enhances diversification
Decentralization,gives room for the diversification and facilitation of various products, markets and activites . Unlike a centralised enterprise that gives little or no room for that kind of input.

3It provides delegated authority which enhances speed and effectiveness as division of labour has been proven to be an important component or ingredient for productivity

4 Executive Development
As a result of the decentralized system, in the nature of authority, the executives in the organisation will have the luxury of advancing and developing their intellectual prowess by taking initiative which will make them ready to fill a higher managerial positions,as the growth of the system is highly dependent on skilled personal.

DISADVANTAGES OF DECENTRALIZATION

1The cost of running a decentralized block chain is highly capital intensive

2It is also highly volatile in nature as it subjected to change

3it increases the risk that involves the illegal and indiscriminate transfer of funds that may lead to problems.

4It is highly complex in nature and difficult to set up

5As much as it increase the rate of public awearness and facilitates initiative it also gives room for conflict of interest since all are giving a voice

WHICH IS MORE PREFERABLE

As you have rightly said prof,in your lecture that the both are essential to firms businesses and government agencies as boths are needed in their own way as the fate of both small and big firms are heavily realiant on these systems.

Hoewver if am to pick then the decentralized system will be my option as it is more convenient and private giving you control over what ever you are into. Truth be told I love any platforms that structures the fate and destinies of people in their own hands,so whatever outcome you get is dependent on you and nobody else.

HOW TO KNOW IF THE BLOCK CHAIN IS CENTRALIZED OR DECENTRALIZED

One way of knowing weather the blockchain is centralized or not is by using a Blockchain Explorer.
A blockchain explorer helps to extracts data from a blockchain. It gets the data so that it can be easily analysed and interpreted by everyone who cares to know. This give room or allows users the privilege to see everything that is going on.

Thanks prof @yousafharoonkhan for this wonderful insight i appreciate you greatly thanks so much
