Describe the process of software data processing

Software data processing on a computer is implemented as follows. After starting for execution of a program stored in external non-volatile memory, it is loaded into RAM. The processor sequentially reads program instructions and executes them. The data required for the execution of the command is loaded from external memory into the RAM and the necessary operations are performed on them. The data received during the execution of the command is written by the processor back to the RAM or external memory.
During program execution, the processor can request data from information input devices and send data to information output devices.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
