Final answer:
Virtual memory allows a programmer to view memory as having multiple address spaces. This system enhances flexibility and simplifies programming by simulating additional memory resources.
Step-by-step explanation:
The concept that allows the programmer to view memory as consisting of multiple address spaces is known as virtual memory. Virtual memory is a system that allows a computer to compensate for physical memory shortages, utilizing a portion of the hard drive as though it were additional RAM. It divides the memory into virtual address spaces, which allows each program to operate as if it has its own dedicated memory space.
When using virtual memory, the operating system manages these address spaces, ensuring that each application has access to the memory resources it needs without interfering with other applications. This technique greatly simplifies programming and enhances the overall efficiency and flexibility of the system by providing programs with more memory than might physically be available on the machine.
