What is an ARM processor and how does it differ from x86?
ARM processors use a reduced instruction set (RISC) architecture that prioritizes power efficiency, while x86 processors use a complex instruction set (CISC) optimized for raw performance. ARM dominates mobile devices and is rapidly expanding into laptops and servers — Apple Silicon and AWS Graviton proved ARM can compete with x86 on performance while using significantly less power.

What is retrieval-augmented generation (RAG)?
Retrieval-augmented generation (RAG) is an AI architecture that combines a large language model with an external knowledge base. Instead of relying solely on training data, the model retrieves relevant documents at query time and uses them to generate more accurate, grounded responses. This reduces hallucinations and keeps answers current without retraining.
