What program allows programs to run and can be changed and accessed at any point?
I am assuming the question here is "what enables multitasking?"
That would be the kernel. The kernel has a component called the "process scheduler" which decides what program gets how much time on the CPU and, in the case of SMP, which core.
A CPU core can only run one process at a time. While multiple cores may enable a CPU to run more than one process at a time, a single core can still only do one thing at a time. One of the jobs of the kernel is to use interrupts to preempt a running process to decide what should run on a core next.
This usually happens under two conditions:
1. A process exhausts its timeslice or,
2. Most commonly, a process makes a system call, usually for I/O, which causes the process to preempt itself for system services.
This all happens so fast the user shouldn't notice it. What looks like 8-9 desktop applications running simultaneously on your desktop is actually processes taking turns very quickly on using the CPU.

What is program-visible registers?
Program-visible registers are a set of registers in a CPU that can be accessed and manipulated directly by software programs. These registers typically store data, addresses, or control information that the program needs during execution. Their visibility allows for efficient data handling and faster execution, as operations can be performed directly using these registers rather than accessing slower memory. In contrast, some registers are internal or reserved for the processor's own operations and are not directly accessible by programs.

What is the purpose of storing a program in memory?
Anything stored in memory can be accessed much faster than items stored on the harddrive. This is basically because of the physical composition of memory chips which allows for much faster data-transfer. The tradeoff is the amount of space that memory provides, and the number of programs that end up sharing the memory. So, when a program is stored in memory, its execution is much faster. However, if a program exists ONLY in the memory, and does not store any data on the primary disk, then when you exit a program, all your data will also be destroyed due to active memory management that takes place. Data will not persist when program exists. Hence, you will need to write the data to a file on the hardisk which can be accessed later and loaded into the memory next time when the program runs.
