Correct Answer - Option 2 : Software is loaded into RAM from secondary storage and is then executed by CPU.

Key Terms

Software:

  • The software comprises the entire set of programs, procedures, and routines associated with the operation of a computer system.
  • A set of instructions that directs a computer's hardware to perform a task is called a program, or software program.
  • The operating system (e.g. Mac OS, Microsoft Windows, Android, and various Linux distributions) is a type of software that is used as a platform for running the applications and controls all user interface tools including the display and the keyboard.
  • Computer software has to be "loaded" into the computer's storage (such as the hard drive or memory). Once the software has loaded, the computer is able to execute the software. This involves passing instructions from the application software, through the system software, to the hardware which ultimately receives the instruction as machine code.

RAM:

  • Random-access memory is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code.
  • random-access memory device allows data items to be read or written in almost the same amount of time irrespective of the physical location of data inside the memory.
  • In today's technology, random-access memory takes the form of integrated circuit (IC) chips with MOS (metal-oxide-semiconductor) memory cells. RAM is normally associated with volatile types of memory (such as dynamic random-access memory (DRAM) modules), where stored information is lost if power is removed.

CPU:

  • central processing unit (CPU), also called a central processormain processor, or just processor is the electronic circuitry within a computer that executes instructions that make up a computer program
  • The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. 
  • The computer industry used the term "central processing unit" as early as 1955.
  •  Principal components of a CPU include the arithmetic logic unit (ALU) that performs arithmetic and logic operationsprocessor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory) and execution of instructions by directing the coordinated operations of the ALU, registers and other components.
  • The fundamental operation of most CPUs, regardless of the physical form they take, is to execute a sequence of stored instructions that is called a program. The instructions to be executed are kept in some kind of computer memory. Nearly all CPUs follow the fetch, decode and execute steps in their operation, which are collectively known as the instruction cycle.

Conclusion: 

  • Computer's performance has a lot to do with RAM. The software applications installed on computers depend on Random Access Memory (RAM) to keep them running while working.
  • RAM functions as the computer's short-term or temporary memory. RAM works in conjunction with the central processing unit (CPU). If RAM is the temporary memory, the CPU is the brain of the computer.
  • The CPU chip retrieves data from the RAM. The chip takes those instructions and begins to move and process data through the motherboard in the correct order to its next designated location.
  • A computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed. The function of secondary storage is the long-term retention of data in a computer system.
  • Secondary memory is not accessed directly by the Central Processing Unit(CPU). Instead, data accessed from a secondary memory is first loaded into Random Access Memory(RAM) and is then sent to the Processing Unit.
  • Hence, from this discussion, it is clear that option (2) is correct.
