Is ROM a secondary storage?

  • Score 4.9/5

There is a key difference between memory and storage. Programs are kept on a storage device and copied into the computer's memory before they are executed . Storage is also called secondary storage. Storage and read only memory (ROM) use non-volatile memory

non-volatile memory
Non-volatile memory (NVM) or non-volatile storage is a type of computer memory that can retain stored information even after power is removed. In contrast, volatile memory needs constant power in order to retain data.

Is ROM a secondary memory?

Computer memory is of two basic types – Primary memory(RAM and ROM) and Secondary memory (hard drive, CD, etc). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.

Is ROM a primary or secondary storage device?

Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.

Is ROM a primary storage?

The two main types of primary storage are ROM, which is non-volatile , and RAM, which is volatile . Non-volatile memory keeps its contents even when the computer is switched off.

Is ROM same as secondary storage?

ROM stands for read-only memory, and the name stems from the fact that while data can be read from this type of computer memory, data cannot normally be written to it. ... In that sense it is similar to secondary memory, which is used for long term storage.
