Qwotable's development is no longer the priority, but some things are still coming.
Qwotable's development has ended, but something new is coming.
Qwotable 3.0 introduces some changes, that are discussed here.
Learn how binary trees organize data, how binary search works, and how to explore trees using different traversal techniques.
Explore the central concepts of information systems, from data, hardware, and software to networks and users. Understand the core structures of the Internet, including end devices, routers, servers, and protocols. Learn about synchronous and asynchronous communication channels, and discover essential security measures such as encryption, authentication, and firewalls that protect data transmission online.
Learn what classes and objects are, how they organize data and behavior in object-oriented programming, and how inheritance helps create relationships between classes.
Discover the basics of cryptology: how data can be encrypted and decrypted using simple methods, the difference between symmetric and asymmetric encryption, and why privacy matters—especially under GDPR regulations in the EU.
Learn what algorithms are, the key principles they follow, and how variables, loops, conditions, and methods work together to solve problems step-by-step.
Data structures organize and manage data efficiently. This guide covered arrays, stacks, and queues, showing how to use them in Java. These basics prepare you for more complex structures like trees.
Learn about the basics of data encoding, from binary numbers and ASCII to color representation with the RGB model. Discover how encoding is used for data compression through algorithms like Huffman coding and Run-length encoding.
