Explanation:
All right, computer modeling is a very useful tool for developers and testers because they can help the developmental process of anything. In our case we chose safety car mechanisms, however, they can apply to almost anything. One benefit would be that the testers would safe on research and development expenses by pursuing computer model tests, instead of a test in real life because they would damage cars. However, one drawback is that they could be wrong in a line of code and have an unrealistic test.

Answer:
D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.
Explanation:
Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost. Non-volatile memory has a continuous source of power and does not need to have its memory content periodically refreshed.
