Final Answer:
The type of memory that might retain information after being removed from a computer and, therefore, represent a security risk is B. Secondary memory. This the correct option is B.
Step-by-step explanation:
Secondary memory refers to non-volatile storage devices such as hard drives, solid-state drives, or external storage media like USB drives. Unlike volatile memory (such as RAM), which loses its contents when power is turned off, secondary memory retains data even when disconnected from a computer. This characteristic makes secondary memory a potential security risk, as sensitive information stored on these devices can persist and be accessed if the storage medium falls into unauthorized hands.
Data security is a critical concern in various industries, and understanding the nature of different memory types is essential for implementing robust security measures. While real memory, static RAM (SRAM), and dynamic RAM (DRAM) are volatile and lose data when power is removed, secondary memory's non-volatile nature poses a higher risk of data persistence. Organizations must implement secure data disposal practices and encryption methods to mitigate the potential security threats associated with secondary memory, especially when handling sensitive or confidential information.
In conclusion, the selection of secondary memory as the answer highlights the importance of recognizing the different characteristics of memory types in the context of data security. Implementing measures to secure secondary memory devices is crucial for safeguarding sensitive information and preventing unauthorized access or data breaches. This the correct option is B.
