Which of the following will not retain data after the computer is turned off?Multiple ChoiceDVDRAMROMHard drive

To determine which option will not retain data after a computer is turned off, let’s analyze each choice systematically:

1. DVDRAM: This is a type of optical disc that can be rewritten and holds data. It retains data even after the computer is turned off, as it is a physical medium.

2. ROM (Read-Only Memory): ROM is non-volatile memory that retains its data even when the power is turned off. This type of memory is used to store firmware and other essential system instructions.

3. Hard drive: The hard drive is a non-volatile storage device that retains all data when the computer is powered off. It stores data magnetically or on flash memory.

4. Final Conclusion: Based on the analysis, none of the options mentioned (DVDRAM, ROM, Hard drive) lose data when the computer is turned off. However, if this was a trick question, generally, RAM (Random Access Memory, which is not listed) is known for losing data after power loss, but from the provided options, all retain data.

Answer

None of the given options (DVDRAM, ROM, Hard Drive) will not retain data after the computer is turned off. All of them are forms of non-volatile storage.
