What is the difference between open market operations and quantitative easing in terms of their impact on the economy?

Open market operations involve the buying and selling of government securities by the central bank to control the money supply and interest rates. Quantitative easing, on the other hand, involves the central bank purchasing long-term securities to increase the money supply and stimulate economic activity. While both aim to influence interest rates and economic growth, quantitative easing is more aggressive and is typically used during times of economic crisis.
