What is Artificial Intelligence (AI)?
Artificial Intelligence refers to machines designed to simulate human intelligence, including tasks like problem-solving, learning, and decision-making.
How is Machine Learning different from Artificial Intelligence?
Machine Learning is a subset of AI focused on algorithms that improve automatically through experience without being explicitly programmed.
What are NLP (Natural Language Processing) algorithms used for?
NLP algorithms help machines understand and generate human language, powering chatbots, translation tools, sentiment analysis, and voice assistants.
What is Quantum Computing, and why is it important?
Quantum computing uses quantum bits (qubits) to perform calculations that would be impossible or take too long on traditional computers. It’s poised to transform cryptography, drug discovery, and AI.
What are Python automation scripts, and what jobs use them?
Python automation scripts are small programs that automate tasks like file handling, web scraping, or system monitoring. They’re widely used in DevOps, QA, cybersecurity, and data engineering roles.
What is DeepSeek AI, and why is China investing in it?
DeepSeek is a Chinese AI initiative developing large language models similar to GPT. China sees it as a strategic asset in competing globally in artificial intelligence.
How do I convert a UNIX timestamp to a readable date?
You can convert a UNIX timestamp using tools like Python’s datetime module, online converters, or command-line tools like date -d @timestamp in Unix/Linux systems.
What’s the difference between Windows 11 Home and Pro?
Windows 11 Pro includes advanced features like BitLocker encryption, Hyper-V virtualization, and remote desktop — which are not available in the Home edition.
What are SRV records in email setup, and do I need them?
SRV records specify services like email, SIP, or chat. They are often used for auto-discovery in corporate environments, especially with Microsoft Exchange or VoIP platforms.
What are the biggest cybersecurity threats in 2025?
In 2025, the biggest cybersecurity threats include AI-driven phishing, deepfake social engineering, supply chain attacks, and cloud misconfigurations.
