Answer:
Explanation:To get the best plant growing conditions, the temperature and humidity (moisture in the air) have to be controlled.
The greenhouse therefore has temperature and humidity sensors linked to a computer, and the computer has a control program storing details of the correct temperature and humidity settings. The greenhouse is fitted with a heater, sprinkler and window motor which are also linked to the computer.
If the humidity falls below the values stored in the program, the computer activates the sprinklers and closes the windows. If the temperature falls outside the values stored in the program, the heater is activated by the computer.

gigahertz (GHz )
Explanation:
A “cycle” is technically a pulse synchronized by an internal oscillator, but for our purposes, they're a basic unit that helps understand a CPU's speed
Control Unit – controls all parts of the computer system. It manages the four basic operations of the Fetch Execute Cycle as follows:
Fetch – gets the next program command from the computer’s memory
Decode – deciphers what the program is telling the computer to do
Execute – carries out the requested action
Store – saves the results to a Register or Memory
Arithmetic Logic Unit (ALU) – performs arithmetic and logical operations
Register – saves the most frequently used instructions and data
