DECENTRALIZED COMPUTING

A decentralized computer system, as opposed to a centralized one, is collection of autonomous computers which communicate with one another to perform a common service. A decentralized system might occupy a single room, but more typically decentralized systems have geographic and organizational diversity.

The world telephone system is the biggest and best example of a decentralized system. It consists of thousands of computers, and almost a billion terminals. Some of the nodes of the system are tiny local PBX's while others are quite large, able to handle many calls per second. Different parts of the system are operated by cooperating organizations with different hardware, different languages and different ideologies. They have agreed to protocols which allow direct dialing from anywhere to anywhere and the consequent automatic routing and billing.

Other examples of decentralized systems can be found in the world travel industry system, inter-connecting travel agents with hotels, airlines, and other reservation systems, and the emerging electronic financial system, connecting financial institutions, businesses and governments.

These systems have the following common features:

* Diverse organizations and organizational procedures,

* Diverse computer architectures, both hardware and software,

* Diverse terminal types,

* Diverse system sizes, from tiny to large, and

* Diverse site environments.

Decentralized computing is a trend in modern day business environments. On the other hand centralized computing was prevalent during the early days of computers. Decentralized computing involves allocation of resources, both hardware and software, to each workstation. In contrast, centralized computing exists when the majority of functions are carried out, or obtained from a remote centralized location.

A decentralized computer system has many benefits over a conventional centralized network. Desktop computers have advanced so rapidly, that their potential performance far exceeds the requirements of most business applications. This results in most desktop computers remaining idle (in relation to their full potential). A decentralized system can utilize the potential of these systems to maximize efficiency. However, it is debatable whether these networks increase overall effectiveness.

All computers have to be updated individually with new software, unlike a centralized computer system. Decentralized systems still enable file sharing and all computers can share peripherals such as printers and scanners as well as modems, allowing all the computers in the network to connect to the internet.

A collection of decentralized computers systems are components of a larger computer network, held together by local stations of equal importance and capability. These systems are capable of running independently of each other.

Cutting people off isn’t strength—It is a trauma response

Your ability to cut people off and self-isolate is not a skill you should be proud of—It is a trauma response Cutting people off and self-isolating may feel like a protective shield, but it is often rooted in unresolved or unhealed trauma and an inability to depend on others. While these behaviors seem like self-preservation, they end up reinforcing isolation and blocking meaningful connections. Confronting these patterns, seeking therapy, and nurturing supportive relationships can help break this unhealthy cycle. Plus, a simple act like planting a jasmine plant can symbolise the start of your journey towards emotional healing. Why do we cut people off and isolate? If you’re someone who prides themselves on “cutting people off” or keeping a tight circle, you might believe it’s a skill—a way to protect yourself from betrayal, hurt, or unnecessary drama. I get it. I’ve been there, too. But here’s the thing: this ability to isolate yourself is not as empowering as it may seem. In fact, i...

Epitome of Equality

First of all This is not to demean any religion.. I am a Hindu by birth, but yes I respect all religions .I offer my daily prayers , fast on holy days , but there was something that was disturbing me . God as per me was a Friend, someone who was by my side always , someone who was a dear friend , but this is not what everyone else thought , for others he was the Judge who gives his verdict always and punishes anyone and everyone . Walk into any temple and you would see , if you have money , you will be treated in a way as if you are the ONLY disciple of the God . I have had too many experiences where I was treated as a second class citizen in the temple . Why? Well I could not afford giving thousands as donation. This is not how it should be , God looks at each one of us with the same divinity .As I mentioned God for me is a friend, so tell me, do we chose friends based on their bank balances? Do we give our verdict on them ? then how can God do it? I know many of us would ...

Does India need communal parties?

I think, it was Tan's post on this blog itself, Republic Day Event, where this question was raised. My answer. YES. we need communal parties even in Independent, Secular India. Now let me take you, back to events before 1947. When India was a colony of the British Empire. The congress party, in its attempt to gain momentum for the independence movement, heavily used Hinduism, an example of which is the famous Ganesh Utsav held in Mumbai every year. Who complains? No one. But at that time, due to various policies of the congress, Muslims started feeling alienated. Jinnah, in these times, got stubborn over the need of Pakistan and he did find a lot of supporters. Congress, up till late 1940's never got bothered by it. And why should we? Who complains? No one. But there were repercussions. The way people were butchered and slaughtered during that brief time when India got partitioned, was even worse than a civil war scenario. All in the name of religion. And there indeed was cr...
