The CPU registers. If the data is too large to physically store in a register, the register stores the memory address containing the data instead (usually a RAM address but could be any address in the physical address space, including ROM and graphic memory). On a 32-bit system, data registers need to be at least 32-bits long in order to store memory addresses.
Proccessing, mostly every program is run using it.
Hmmm, a CPU (processor) stores no data. RAM or Memory can store data as long as the computer is ON and the Hard Drive can store data indefinately (forever).

Random Access Memory (RAM) is a hardware device that allows information to be stored temporarily.
The central processing unit (CPU) is the part of a computer that processes data. In the past, the CPU itself used to take up a large cabinet that was full of many circuit boards. Nowadays, multiple CPUs fit inside a single chip, and that chip fits onto a single circuit board known as a motherboard.
RAM (Random Access Memory) temporarily stores data and programs that the CPU is actively using, allowing the computer to run faster and multitask efficiently.
The CPU
No data is stored in the CPU. The CPU only performs arithmetic and logical operations. However, the CPU is provided with a small memory unit called cache, which rapidly feeds the CPU with data to calculate.

Data is not stored directly in the CPU; instead, it is processed in the CPU's registers, which are small, fast storage locations for immediate data manipulation. For longer-term storage, data is held in RAM (Random Access Memory) while the CPU is actively processing it. When the CPU needs to access data, it retrieves it from RAM or caches, which are faster memory layers close to the CPU. Non-volatile storage, like SSDs or HDDs, is used for permanent data storage when the system is powered off.
ROM (Read-Only Memory) and RAM (Random Access Memory) interact with the CPU by providing different types of data storage. ROM contains permanent instructions essential for booting the system, while RAM provides temporary storage for data and programs that the CPU actively uses during operation. The CPU retrieves instructions and data from RAM for processing, and it may access ROM for essential firmware instructions if needed. This collaboration ensures that the CPU can execute tasks efficiently by utilizing the fast access speed of RAM and the stable data provided by ROM.
memory range
The registers in a CPU are organized according to their purpose. There are data registers and address registers. The address registers are in charge of pointing out where certain data stores are.
The main component that receives data from the CPU is the system memory (RAM), which temporarily stores data and instructions for quick access by the CPU. Other components that can receive data include input/output devices, such as hard drives, graphics cards, and network interfaces, which facilitate communication between the CPU and the external environment. Additionally, the motherboard's chipset manages data flow between the CPU and these components.
The working space for the CPU, often referred to as memory or RAM (Random Access Memory), is where the CPU stores data and instructions that are actively being processed. This space allows for quick access to information, facilitating efficient computation and multitasking. Additionally, cache memory, a smaller and faster type of volatile memory, helps speed up access to frequently used data and instructions, enhancing overall performance.
The percentage of time the CPU is actively processing data is referred to as the CPU utilization rate. This metric is commonly used to monitor the workload of the CPU and can help identify potential performance issues or bottlenecks in a system.
