Emerging Technologies

TechnologyWhat It Is
BlockchainA decentralised, tamper-resistant digital ledger technology (used in cryptocurrencies)
Quantum ComputingComputing using quantum bits (qubits) that can represent multiple states simultaneously, enabling vastly faster processing for specific problems
Augmented Reality (AR)Overlays digital content onto the real world (e.g., AR filters)
Virtual Reality (VR)Creates a fully immersive, simulated digital environment
5G TechnologyFifth-generation cellular network offering high speed and low latency
Edge ComputingProcessing data closer to where it's generated (the "edge") rather than a centralised cloud server
💡 AR overlays digital elements onto the real world (you still see your surroundings); VR fully replaces your surroundings with a simulated environment.
