System Execution

"System execution" refers to the process of a computer system actively carrying out the instructions of a program, essentially meaning the computer is running the program and performing the actions defined by its code, including interpreting instructions, performing calculations, and managing data to achieve a desired result. 

Key points about system execution:

• Interpretation of instructions:

  The computer reads each instruction in the program and translates it into actions the hardware can understand. 

• Memory allocation:

  During execution, the system allocates memory to store the program's data and instructions. 

• Central Processing Unit (CPU):

  The CPU is the core component responsible for fetching, decoding, and executing instructions one by one. 

• Input/Output operations:

  System execution may involve interacting with external devices like keyboard, mouse, or display to receive input or present results.
