Questions and Answers

Which of the following is a key characteristic of RAM (Random Access Memory)?

  • RAM requires special high-current devices to program it
  • RAM allows the CPU to both read and write data (correct)
  • RAM can only be read from, not written to
  • RAM is a non-volatile memory device

    • What is the key difference between RAM and ROM (Read Only Memory) in terms of memory operations?

  • RAM is accessed randomly, while ROM is accessed sequentially
  • RAM can only be written to, while ROM can only be read from
  • RAM requires special programming devices, while ROM is factory programmed
  • RAM is volatile, while ROM is non-volatile (correct)

    • Which type of ROM allows the user to erase and reprogram the memory using electrical signals?

  • EEPROM (Electrically Erasable Programmable ROM) (correct)
  • PROM (Programmable ROM)
  • EPROM (Erasable Programmable ROM)
  • Flash memory
