Cryptocurrency* * is a digital or virtual currency that uses cryptography* for security. The most well-known example is Bitcoin* , but there are thousands of alternatives, often called altcoins.
These currencies typically run on a blockchain* , a decentralized ledger that records all transactions across a network.
Every modern website is built on three core technologies: HTML* , CSS* , and JavaScript* . While HTML* structures content, CSS* handles visual styling, and JavaScript* brings interactivity.
In recent years, responsive design and accessibility have become essential components of good web development* .
Classical music* spans several eras, from the Baroque period* to the Romantic era* . Composers like Johann Sebastian Bach* are known for complex fugues, while Ludwig van Beethoven pushed musical boundaries.

Brewing the perfect cup of coffee requires more than just pressing a button. From the grind size to the extraction time* , each step matters.
For example, using a French press* gives a full-bodied taste, while pour-over* methods emphasize clarity. The coffee-to-water ratio* is also crucial—too strong or too weak, and you miss the sweet spot.
Machine learning* * * is a subfield of artificial intelligence* that gives computers the ability to learn without being explicitly programmed. A common method is using neural networks* , which mimic the structure of the human brain.
Other important terms include supervised learning* , where models learn from labeled data, and unsupervised learning* * , where patterns are found without predefined labels. Over time, models improve through a process called training.
Neural networks are a type of machine learning model inspired by the structure of the human brain, composed of layers of interconnected nodes (neurons).
