A blockchain is an encrypted database that connects encrypted data blocks to establish a chronological single-source-of-truth for the information, making it difficult or impossible to edit, hack, or cheat it.The difference between a traditional database and a blockchain is that blockchain is decentralized.

Traditional databases are centralized, which means they are controlled by a single administrator.There is no administration with a Blockchain. It's a peer-to-peer network, which means that everyone is linked to it and that each node has a copy of the current database.

It's a great innovation to use when you need to manage and secure digital interactions or establish a decentralized, shared system of record also this technology that allows cryptocurrencies (Bitcoin).

√ Quantum Computing

° Quantum computers are the latest generation of supercomputers that uses quantum bits rather than the regular binary system. It works with 4 different varieties of 0s and 1s, which enables it to complete processes that would take traditional computers ten thousand years in just 3 minutes.

° A quantum computer could calculate one trillion operations per second!

° These computers are so powerful, they can break through any 256-bit encryption in seconds. They use algorithms that are able to complete seemingly impossible tasks efficiently. Quantum computers are already developed by the largest corporations such as Microsoft, Google, IBM, etc.

✓ Google

Larry Page and Sergey Brin founded Google on September 4, 1998, while both were Ph.D. students at Stanford University in California.

The entire name of GOOGLE, Global Organization of Oriented Group Language of Earth, does not exist.

Google's name is a parody on "googol," a mathematical word for the number 1 followed by 100 zeros. 

The founders' objective, it is said, was to arrange the endless amount of information on the internet.

Google's purpose is to organize the world's information and make it accessible and helpful to everyone. 

As a result, Search makes it simple to find a wide range of information from a variety of sources.

LiFi is a wireless optical networking system that transmits data using light-emitting diodes (LEDs). 

LiFi is made to work with LED light bulbs, which are comparable to those found in many energy-conscious homes and offices. 

LiFi bulbs, on the other hand, are equipped with a chip that modulates light invisibly for optical data communication.

The term was first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh.

LiFi, on the other hand, uses light waves on the electromagnetic spectrum to transport data and is thus safe of damaging radiofrequency radiation.


LiFi's Advantages:

-Significantly faster than Wi-Fi.
-10000 times the radio frequency spectrum.
-More secure because data can't be intercepted unless there's a direct line of sight.
-Prevents riders from piggybacking.
-Removes network interference from nearby networks.
-Doesn't obstruct the flow of information.

√ IT automation is the use of instructions to create a repeatable process that replaces an IT professional's manual work in data centers and cloud deployments.

• Automation repeats a task without the need for human intervention.

√ This is how it works:

• IT automation makes use of software tools to specify and carry out a set of specified actions that are triggered either manually or by an external trigger, such as a shift in IT capacity need.

✓ Edge computing is a form of computing that is done on site or near a particular data source, minimizing the need for data to be processed in a remote data center.

✓ How does it work?

* Edge computing works by capturing and processing information as close to the source of the data or desired event as possible. It relies on sensors, computing devices and machinery to collect data and feed it to edge servers or the cloud.

✓ What is the benefit?
* Speed and latency
* Security
* Cost saving
* Greater Realiblity

✓ Robotic process automation (RPA) is a software technology that enables the creation, deployment, and management of software robots that imitate human activities while dealing with digital systems and software. 

* Software robots, like humans, can grasp what's on a screen, complete the correct keystrokes, navigate systems, discover and retrieve data, and do a variety of prescribed operations. 

However, software robots can do it faster and more reliably than humans, as they do not need to stand up and stretch or take a coffee break.

✓ Advantage of RPA
* Cost-Effective
* Accuracy and Quality
* Consistency
* Improved Analytics
* Increased Customer Satisfaction

On August 6, 1991, the first web page was launched. Tim Berners-Lee created it to provide information on the World Wide Web project. The European Organization for Nuclear Research, CERN, used a NeXT computer to run it. http://info.cern.ch/hypertext/WWW/TheProject was the first web page address. The Web was created to address the demand for automated information sharing among scientists at universities and research organizations around the world.

Reasons why we need to use VPN?

1. Protects your private information-
by masking things like your IP address, location, and search history, you can prevent websites, internet browsers, cable companies, internet service providers (ISPs), and others from tracking you.


2. Avoid bandwidth throttling-
If you've noticed slower internet speeds on different websites and at different times, you may have encountered bandwidth throttling. ISPs — or anyone with administrative access to your network — could be to blame for the slowdown. A VPN can be useful. It can slow down your device by encrypting its internet traffic.

3. Access geo-restricted services such as Netflix-
Some VPNs may be able to access geo-restricted content such as Netflix and other providers*. How? A VPN can change your IP address to make a content provider believe you're browsing in another location or region where access is permitted. Always read the Terms of Service agreements to find out what your streaming service allows and follow those guidelines.

4. Provide network scalability-
As businesses expand, so do the costs of establishing a dedicated private network. Internet-based VPNs allow businesses to tap into existing network lines and network capability, potentially giving remote and international locations better reach and service quality.

Benefits of saving files in the cloud

✓ Anywhere File Access

Cloud storage allows you to access your files from anywhere you have Internet access. 

Given the unstoppable trend of BYOD and the proliferation of mobile devices, this effectively means that workers' productivity will not be harmed by an unnecessary trip back to the office to retrieve documents stored on an office computer.
✓ Automatic Data Backup

Saving files in the cloud is a simple yet effective way to protect against the untimely demise of a failed hard disk drive or a laptop that requires immediate service.
✓ Security

Cloud servers also provide automated backups and snapshots to ensure the safety of your data.
✓ Easy Sharing

You can easily share access to a particular cloud environment or to the complete account with some other user.

✓ Synchronization

You can only access your data from a specific location when using local file storage. 
With cloud storage, everyday devices such as your PC and smartphone can serve as access points. 
Accessing and synchronizing files is simple with any device that has an internet connection.
