Explanation should include

terms, such as schematic (a simple way to illustrate all the components and connections in a hydraulic system)
symbols, such as
- lines styles that represent hydraulic hoses, pipes, and tube assemblies
- colliding lines (connected or separate)
- component shapes
  - circle - rotary components - motors, pumps
  - diamonds - fluid conditioning components - oil filters, heaters, coolers
  - squares - valve components - relief valves, pressure reducing valves, counterbalance valves
- operator symbols – drawn beside a component symbol to show how that component is controlled – solenoid, spring, mechanical linkage, pneumatic pilot, hydraulic pilot
- miscellaneous symbols – variable adjustment, tank/reservoir, rotation arrow, ball valve, check valve, orifice.
