The operating system does. At least if it supports virtual memory. If your OS does not, (e.g. if you use DOS or another ancient OS) a program can do anything with the RAM. Note that (at least) in the Intel x86 architecture, some (relatively small) areas of memory are not RAM at all. They are usually reserved by the hardware for other stuff like memory-mapped devices or even the BIOS ROM.

RAM, or random access memory.
Random access memory (RAM) is the machine's working memory. All programs and data must be loaded into RAM in order for the central processing unit (CPU) to execute those programs.
An operating system is software that manages computer hardware, software resources, and provides services for computer programs. It serves as an intermediary between users and computer hardware, enabling the execution of programs and the management of resources such as memory, storage, and input/output devices. Examples of operating systems include Windows, macOS, and Linux.

In computing DMA stands for Direct Memory Access, therefore; all modern operating systems and the programs aka software written for them will directly access memory. The memory it accesses is called RAM for Random Access Memory. RAM is volatile, meaning temporary, where the data is lost when a computer is powered off or another program or process writes to the same address or location in the RAM module(s). Google 'Random Access Memory' for more on that.
ram is random access memory and ROM is read only memory
Random Access Memory (RAM) and Processor Controls PC Software.
The computer's Random Access Memory (RAM) temporarily stores data and programs while your computer is on.
Synchronous dynamic random access memory (in other words fast access memory that the computer uses for the operating system/kernal, and running programs)
RAM (Random Access Memory)
Both. The software resides in the nonvolatile memory when it is not being run, and a copy is loaded into main memory when it is being run. Programs have to reside in RAM in order for the CPU to process their instructions.
Software or "programs" are a long list of instructions that "tells" the computer or "hardware" what to do. Without software, computers are useless. Systems software is software that controls a computer. Applications is software that a user uses to carry out a task, like a word processor. Systems software enables applications to use the hardware, organises files, manages memory and many other activities that keep a computer working or operating, hence the name operating systems.
