A 'strut' is an abbreviation of the word 'Macphereson strut - named after its Scottish inventor.

A 'shock' is an abbreviation of the word 'Shock absorber'.

The Macphereson strut is a suspension component that has a 'damper' (or shock absorber) and a heavy duty spring all in the same unit.

The spring allows the vehicle to travel over bumps without the vibrations from the road surface transferring to the vehicle body and the Shock absorber is designed to remove the oscillations in the spring caused by the road surface (it slows it down and stops it from continually bouncing by having a 'Dampening' effect).

A 'Shock absorber or Damper' is a single component that is part of the suspension doing the same job as above but is a separate unit to the road spring which allows it/them to be removed or replaced independently of each other.
