The two basic types of memory in a computer are RAM and ROM. RAM (Random Access Memory) is volatile memory used for temporary storage while the computer is running, enabling quick access to data. ROM (Read-Only Memory) is non-volatile memory that permanently stores critical system information even when the computer is off, like firmware or the BIOS.
