CEVAP:

Random access memory (RAM) is used to store programs that are currently running. It can transfer data much faster than the hard disk since information is accessed randomly instead of sequentially. However, unlike the hard drive, RAM is volatile. If the computer is turned off, all data stored in RAM is lost. Thus, the computer also needs a persistent data storage that retains data when the computer is turned off. Hard disk drives (HDDs) and solid-state drives (SSDs) are the two commonly used types of persistent storage. The SDDs have faster reading and more speed writing systems compared to HDDs. Read only memory (ROM) is a permeant memory. ROM can be read but not erased or overwritten. Firmware is a small and permanent software programmed into a read-only memory.
