Compasses have been used for centuries to help people find their way around. A compass is a simple tool, but it can be beneficial, especially when trying to find your way around a large city. Google Maps has a compass feature that can be very helpful if you're trying to figure out where she is and how to get to your destination.

Web 1.0: Read-only access
The first phase of Internet evolution is Web 1.0, or read-only access. The concept of Web 1.0 is as simple as it gets: an internet that functions as a library. Users can search for information by keyword but cannot add their content to existing websites—the information on web pages isn’t interactive; you can only view what has been provided on those pages.
Web 1.0 was initiated in 1989 with Tim Berners-Lee’s invention of hypertext transfer protocol (HTTP) technology, which is essential to creating a link between pages. The Web has grown significantly since its inception. It now provides users with multimedia content like video and audio clips—content that wasn’t available during Web 1.0—but it remains a non-interactive platform for getting information on specific topics.
Web 2.0: Collaboration tools
Wikis are a great example of Web 2.0 tools; they allow multiple users to edit a page at once without overwriting anyone else’s work. These tools require more effort than other types of Web 2.0 technologies (there is some setup involved), but if you have a group project, or your business requires lots of collaboration with team members around the world, these can be extremely useful—and save you tonnes of time in communication costs!
Online collaboration platforms are a great option for businesses of all sizes; they allow you to easily find people who have relevant skills or knowledge for your business to get help with specific tasks or projects.
Web 3.0: A Semantic Web of Data
Web 3.0 is a new internet that gives power to people without programming knowledge (AKA: users). This website will be decentralized in nature and focused on providing data in semantic ways.
A lot of big data and machine learning algorithms are already based on semantics. For example, Amazon uses product links to organize products in categories that are related by keyword. It makes searching for similar items easier (e.g., Product A = Buyers who bought Product B also bought Product C). When you type questions into search engines, Google uses its Knowledge Graph to return answers instead of webpages with information when you type questions.
On a bigger scale, imagine if smart cities were built where IoT data from all sensors could be interpreted as a semantically connected network of information. For example, If sensor A detects a decrease in water levels and sensor B detects an increase in electricity consumption, they could correlate their findings together to indicate that there is a leak in pipe C that is causing a pump on device D to activate, causing an increase in energy consumption. That would be pretty incredible!
What is blockchain technology?
The blockchain is a public ledger of all Bitcoin transactions that have ever been executed. It is constantly growing as "completed" blocks are added to it with a new set of recordings. The blocks are added to the blockchain in a linear, chronological order through cryptography, and they cannot be altered retroactively without modifying all subsequent blocks.
The blockchain is a distributed database—to achieve independent verification of its chain of ownership, each network node stores its copy of the blockchain. Approximately six times per hour, a new group of accepted transactions, a block, is created, added to the blockchain, and quickly published to all nodes.
