Kernel memory is best described as volatile because it resides in the computer's RAM (Random Access Memory). This type of memory is temporary and is cleared when the system is powered off. Volatile memory contrasts with non-volatile memory, which retains information even when the power is off, such as hard drives or solid-state drives.

Kernel memory is essential for the operating system's core functions, managing processes and system resources real-time. As the system operates, it continuously writes to and reads from kernel memory, which reinforces the notion of its volatile nature. If the system doesn't have power, all the data held in kernel memory is lost, which is a characteristic feature of volatile memories.

Writable memory refers to the ability to change its content, which may be true for kernel memory, but it does not specifically define its volatility. Dynamic typically refers to memory that changes frequently, but again, it does not reflect the key characteristic tied to the loss of stored information after power loss. Therefore, volatile stands out as the most appropriate descriptor for kernel memory.
