What is nutrient cycle?

What is clock cycle and what is the difference with it and tick?

• I know the difference between Machine cycle and Clock cycle, and I have done a lot of search. Someone says: On each tick or pulse another operation can be started --- http://bottomupcs.sourceforge.net/csbu/c1453.htm That's mean tick is the same thing with pulse. A cycle generally refers to a clock cycle (a single tick of the internal clock.)  http://superuser.com/a/239182/163308 That's mean clock cycle is the same thing with tick. And another says: Each clock cycle consists of eight clock pulses. ---  http://computermuseum.informatik.uni-stuttgart.de/dev/ibm_5110/technik/en/prozessor.html That's mean clock cycle consists of eight ticks. I am confused.

• Answer:

  It is possible that the definition is architecture-dependent. Very old technology, or technology not found in mainstream processors, may have a different definition of clock cycle and tick. As for the link you found, it is possible that each stage of that particular CPU's execution (Instruction cycles - Execution cycles) consists of some sub-cycles or pure delays that is needed for its logic gates to finish a certain kind of operation. If you see them defined in a certain way in a documentation for some product "X", and that documentation is intended for electrical and electronic (digital hardware) engineers who will work with that product, then you can be sure that whatever unusual definition must be the intended (definitive) definition - just for that product "X".
