Before you go deeper into understanding what is Ethereum, you have to understand what the internet is. Today, all personal data, passwords and financial information are stored to a great extent on other computers, computers or servers owned by companies such as Amazon, Facebook, and Google.
These settings offer many features that allow business owners to make their business secure. These companies have teams of specialists to help store and secure data and eliminate costs that come with long-term extensions.
Brian Behlendorf Web Server Builder "Apache Web Server" - The central system of information or the Internet has generally been called "apocalyptic sin". Also, the same person with many people believes that the Internet was and should always be decentralized.
A fragmented movement has arisen around the use of new tools, including Blockchain, to help achieve this goal of Internet decentralization.
Ethereum is one of the latest technologies to join this movement.
While Bitcoin aims to make PayPal and online banking in the last box, Ethhereum has the goal of using Blockchain to replace third parties locally and electronically such as those that store data, transfer mortgages and track complex financial instruments.
Ethereum, Unified Universal Computer!
In short, Ethereum wants to be the "universal computer" computer of democratic decentralization ... which we can consider as the new paradigm of servers.
With Ethereum, servers, and clouds are replaced by thousands of so-called "nodes," or "peers" run by volunteers from around the world (thus creating a "decentralized, democratic global computer").
The vision is that Ethereum will make maintenance, documentation, security and data preservation in the hands of the people (Metallurgical"miner"- in the terms of the Blockchain) with their computers from anywhere in the world and enable them to compete for services on top of the Ethereum structure Technology.
As you browse and move between products on an e-commerce application or website, for example, you'll see a variety of color spots that represent everything from banking to fitness to messaging. These applications depend on your company (or another third-party service) to store your credit card information, your application activity, your purchases, and other personal data (you may not really know where to store it), a time that is calculated to be deleted after you but in fact it will remain forever on servers controlled by third parties.
Your choice of applications is also governed by a third party, where Apple and Google control your choice and make you choose specific applications that you can download.
Take an example of online document saving and editing, such as “Evernote or Google Docs”. If you are an author or intellectual property owner, even before you publish it for the first time, Google can know what you intend to publish in the future.
On the Ethereum, according to the data distributed and encoded you control the data alone (because it is encrypted and decrypted by your hand) because you own its own key, also all your creations and all your works have a common key in your name or in the name of your organization cannot change This is because it is registered in the blockchain and encrypted, (no one without your own key cannot open your own network) for the data distributed to the participants in the Ethereum, the unified global computer.

The idea is that no one can control what you own either they change or change what you own as if you have an offline computer and store all your data. Only you can make changes, not any other entity. But Ethereum, the standard universal computer, is available to you at any time and can reach your data from anywhere in the world and across any device you want.
Ethereum, Unified Universal Computer. In theory, it combines the control that people have had over their information in the past with easy access to information that is used in the digital age. Each time you save edits, add or delete notes, each node on the Ethereum, the Unified World Computer, makes the change.
