Expert Q&A; Done Select all of the following statements that are true. If you don't recall the answers from the lecture, you are welcome to search the course Module slides or use your favorite Internet search engine. O Paper tape cannot be used as memory. Random Access Memory (RAM) is volatile memory that can be read or written at any address. ORegisters are not memory O Some memory is non-volatile meaning that it preserves the values of bits even when power is off Registers are typically the fastest memory in a computer. Machine instructions usually read and write bits from registers Read Only Memory (ROM) cannot be used to store programs because store data. O programs need to be modified (re-written) as they run. ROM is only used to Volatile memory is always faster than non-volatile memory. Faster means than slower memory Some memory is volatile meaning that the values of bits are lost when the O the values stored in memory can be read or written more times per second power is off

Explanation / Answer

1. False. Paper Tape has punched holes to store data, so it is a form of memory.

2. True. Ram is a volatile memory, in which read and write operations take almost same amount of time irrespective of location of data.

3. False. Registers are volatile memory units that are used to store data and are located in the CPU.

4. True. Non-volatile memory is typically used for long time storage of data even after the power is switched off. Most common example of a non volatile memory is Hard Disk Drive.

5. True. Registers are fastest memory in cpu, although they are very small in size.

6.True.  RAM is used for storing temporary operations and running programs while ROM is used to store unchanging data about basic processes because ROM cannot be continuously re-written as it will be highly inefficient.

7. True. Volatile is way faster than non volatile memory.

8. True. Volatile memory only maintain data when the power is switched on. It loses data when power is switched off. Example of volatile memory includes RAM, processor caches.
