Hurricanes are large tropical low pressure areas with winds of 74 miles per hour or greater that occur in the Atlantic or Eastern North Pacific. They occur north of the equator and have a counterclockwise rotation. They are hundreds of miles across.
Tornadoes are small usually very intense low pressure areas that typically originate from rotating thunderstorms (supercells). They are much much smaller than hurricanes--the biggest one ever recorded was only about two and half miles across.
"Cyclone" is a bit confusing because it has three different meanings, all of which are acceptable in their context.
1. It can refer to ANY low pressure area, ranging in size from a dust devil to a hurricane. Normally their winds rotate counterclockwise in the northern hemisphere and clockwise in the southern. This is called "cyclonic" rotation, and the opposite is called "anticyclonic" rotation.
2. It can refer to a large tropical low pressure area occurring in the Indian Ocean or Bay of Bengal. It is exactly the same thing as a hurricane but located in a different place.
3. It can be used as a synonym for a tornado in the US and Canada. Oddly enough, since tornadoes can sometimes rotate clockwise in those locations, it is possible for a "cyclone" to rotate anti-cyclonically. (Silly but true).

Hurricane, Cyclone and Typhoon are the same phenomenon only called by those different terms in different regions of the world. Hurricane is use in America, Typhoon in Asia, Cyclone (or Tropical Cyclone) in Australia and the South Pacific. Cyclones/Typhoons/Hurricanes are usually borne over warm tropical waters and dissipate some time after they make landfall over a continent. A Tornado is born over land and causes damage in a very tight corridor at much higher speeds. A tornado can arrive as quickly as it departs. Note: Hurricanes and Typhoons rotate the in the opposite direction to Cyclones (which are a southern hemisphere thing).

Tornadoes and cyclones are the same thing. Except cyclones might be bigger. Twisters are also the same thing.
Hurricanes are somewhat like tornadoes w/ water. They form a large storm system (normally) that includes high winds (over 100 mph) and rain, along with flooding and high water from the ocean. Hurricanes can progress over land, but they are most deadly on the ocean. The storm can carry heavy rain hundreds of miles inland, and cause thunderstorms and sever flooding.
Tornadoes form on land most of the time, and are most commonly found in the Midwest (AKA "Tornado Alley") They originate in wall clouds.

Cyclones and Tornadoes are basically the same thing. The difference between tornadoes and hurricanes is that hurricanes form over water and get weaker over land, and tornados form over land and sometimes become water spouts, or water tornadoes.

The word "cyclone" technically refers to ANY low pressure system that rotates counterclockwise in the northern hemisphere, or clockwise in the southern hemisphere.
Tornadoes and hurricanes are two different types of cyclones, born and driven by different mechanisms.
