Accordning to Reference.com, fetch, decode and execute is the basic operation or instruction cycle of a computer's central processing unit in retrieving instructions from programs through the random access module and hard drive. This process is continuously repeated while a computer is in operation.Know More
Fetch is the first step in a sequence of actions performed by the CPU to determine where a request to execute a program or action originated. It relays a series of binary codes to the hard drive and the RAM to process the fetch code for execution. The fetch code also tells the CPU where a program is stored in the hard drive and transfers the instructions to the RAM for execution.
The next sequence is called the decoding action, in which the CPU identifies which computer components are required and assigns them to execute a requested function. This sequence also identifies and provides the required parameters to execute a request successfully.
The execution sequence is the phase in which the CPU directs components how to complete tasks and continuously communicates with them until instructions gathered from the fetch and decode phases are successfully executed.
To speed up operation, modern CPU architecture incorporates an instruction pipeline designed for multiple instruction-cycle executions at the same time.Learn more about Computer Programming
The rock cycle is the transformation of one type of rock to another through heat, pressure, weathering and erosion. First proposed by James Hutton in the late 18th century, the cycle is an ongoing process that affects the rock that composes mountains as well as rock deep below the Earth’s surface. However, it is important to realize that not all rocks go through every stage of the cycle.Full Answer >
The water cycle consists of three stages. The first is evaporation, as the sun's heat converts liquid water from rivers, lakes and oceans into water vapor. The second stage is condensation. As water vapor rises into the atmosphere, it cools and condenses into droplets of liquid water. Wind currents carry this water as clouds. The third stage is precipitation, in which water falls back to Earth as rain or snow.Full Answer >
A game of fetch relies upon a cat's natural urge to chase and retrieve prey for its young kittens and to carry things in its mouth. Cats are natural-born hunters. They have instincts which make running play irresistible and encourage them to carry prey or toys.Full Answer >
Fetch is the distance that wind has traveled over open water without encountering an obstruction. In normal circumstances, long fetches create larger, more powerful waves than short fetches.Full Answer >
