What is the difference between preignition and detonation and how do they cause engine damage?

They are the same thing. They cause damage by applying the force of combustion to the piston before it has reached the top of its stroke, which basically pushes it "backwards"

Why does low octane gas make an engine knock?
Low octane gasoline ignites at a lower temperature/compression than higher octane gasoline causing it to (depending on circumstances) ignite before the spark happens. This "preignition" or "detonation" causes excessively high cylinder pressure in the combustion chambers and at piston-to-connecting-rod near TDC and typically produces a knock noise which. The preignition or "spark knock" can also damage pistons, valves, connecting rods, and bearings. Repairs may require rebuild of the engine.
What is difference between damage and defect?
The difference between damage and defect is damage is when an item is broken or destroyed. A defect is usually a mechanical defect that prevents an item from working correctly.
What is a knock sensor?
A knock sensor is a device that senses detonation. Detonation occurs in the engine when the fuel begins to burn prematurely; it can cause substantial damage to the engine.

What do you check if your 96 Ford Explorer XLT has severe detonation with 87 octane fuel?
Start higher octane fuel and check the timing. If it is severe detonation, serious engine damage has occured.

What is the difference between brain damage and brain injury?
The difference is that one can have a brain injury and not have brain damage. Essentially, brain damage is caused by injury or trauma to the brain. However, not every injury to the brain will cause brain damage.

What is the difference between 1sec and 3sec duration of short-circuit withstand capacity?
The difference between 1 second and 3 seconds is 2 seconds. In terms of short-circuit withstand capacity, it can mean the difference between no damage and damage occurring to the equipment and wiring. Heat rises extremely fast in a short-circuit situation, and you want your protective device to trip before damage is done.
