During a sudden power outage, one internal memory loses data whilst the other remains unaffected. Identify these two types of internal memory and explain the main difference between

them.

Answer 1

The two types of internal memory you are referring to are volatile memory and non-volatile memory.

1. Volatile Memory: This type of memory requires a constant power supply to maintain the stored information. When there is a power outage, volatile memory loses all its data. The most common example of volatile memory is Random Access Memory (RAM), which is used by computers and devices to temporarily store data that is actively being used or processed.

2. Non-volatile Memory: This type of memory retains its data even when the power is turned off or lost. Non-volatile memory is used for long-term data storage. Common examples include Read-Only Memory (ROM), flash memory (like USB drives and SSDs), and hard drives.

Main Difference: The fundamental difference between volatile and non-volatile memory is their data retention capability during power loss. Volatile memory loses its data when power is lost, while non-volatile memory retains its data even without a power supply. This makes non-volatile memory suitable for long-term storage, while volatile memory is essential for fast data access and processing during operation.
