Can you explain the difference between a hurricane and a typhoon?

A hurricane is a tropical cyclone that forms over the warm waters of the Atlantic Ocean or Northeast Pacific Ocean. It has sustained winds of 74 mph (119 km/h) or higher, and usually rotates around a center of circulation. Typhoons are similar in many ways to hurricanes but form over the warm waters of the Northwest Pacific Ocean. They have sustained winds of at least 118 mph (190 km/h), and they rotate around a center of circulation.
