Where are the programs that control the operation of the processor stored? Where is the data stored while the processor is working with them?

A microcircuit is soldered on the motherboard, which stores programs for the processor. With their help, the processor interacts with hard drives, floppy drives, USB ports, etc. Programs are written to the microcircuit during the manufacture of the motherboard.

To process information, the computer uploads data to the RAM. This memory with several strips (from 1 to 4) is installed in the connectors on the computer motherboard. If this amount of memory is not enough (when many applications are open), then some of them are written to the hard disk; during further work with the application, the data is loaded back into RAM. The process of loading and unloading information greatly slows down the computer, so users try to install more RAM into the system.
