To answer the question, we need to determine what 'WORM' stands for in computer-related activities. The options provided are:

1. Write On Random Memory
2. Write On Real Memory
3. Write Once Read Many
4. Write Once Read Memory

Explanation:

'WORM' stands for Write Once Read Many. It is a type of data storage technology that allows data to be written to a medium once and read multiple times. This technology is commonly used in optical storage media, such as CDs, DVDs, and certain types of servers and archival systems. Once the data is written, it cannot be altered or deleted, making WORM an effective solution for archives that need to remain unchanged over time.

Let's evaluate why the other options are incorrect:

• Write On Random Memory: This doesn't fit the standardized terms in ICT related to persistent storage. 'Random memory' is not a commonly used term in this context.
• Write On Real Memory: This term does not apply because 'Real Memory' isn't typically associated with WORM. Real memory generally refers to the physical memory (RAM), which is not a WORM technology.
• Write Once Read Memory: Although it sounds similar, this is not the correct full form of WORM. It lacks the 'Many' aspect that distinguishes WORM's purpose.

Therefore, the correct answer is Write Once Read Many.
