What can execute millions of stock purchases and sales between different cities in seconds through high-frequency trading?

• A. Supercomputers
• B. Mobile devices
• C. Personal computers
• D. Quantum computers

Answer: (A)

High-frequency trading relies on processing vast streams of market data and placing orders in extremely small timeframes. The speed comes from immense computational power and highly parallel processing, plus the ability to connect directly to exchanges with ultra-low latency networks. Supercomputers are designed with thousands or millions of processing cores and specialized hardware that can crunch data, run complex trading algorithms, and route massive numbers of orders in parallel. That combination lets them execute millions of transactions across different cities in seconds, outpacing other devices. Mobile devices and personal computers don’t offer the same level of speed, reliability, or throughput needed for such rapid, continuous trading, so they aren’t suited for high-frequency trading. Quantum computers, while powerful for certain problems, aren’t yet practical for real-time, latency-sensitive market operations—the hardware and software ecosystems aren’t aligned for executing live trades with the required immediacy.
