When the CPU does computing, it stores information in what first?

The CPU primarily uses registers to store information temporarily while it performs computations. Registers are small, fast storage locations within the CPU itself that hold data, instructions, and addresses that the CPU needs for immediate processing. Because registers are located inside the CPU, they provide the fastest access to data, allowing for quick calculations and operations.

In computing, after the CPU retrieves instructions or data from memory, it may transfer this information into registers to execute operations more efficiently. While caches and RAM also play critical roles in managing data for processing, they operate at different levels. Caches serve as intermediary storage between the CPU and RAM, speeding up data access, but they are not where computations begin. RAM stores larger amounts of data and program instructions temporarily during processing but is slower than registers. Therefore, registers are the first stop for the CPU when performing its computations.
