B. The amount of RAM in the device
C. The size of the device’s hard drive
D. The color of the device’s casing
Correct Answer: A. The clock speed of the processor and B. The amount of RAM in the device. Explanation: The computing power of a device is determined by various factors such as the processor clock speed, the number of processor cores, the amount of RAM, and the size of the hard drive or storage capacity. The clock speed of the processor determines how quickly it can perform calculations, while the amount of RAM allows the device to handle more data at once and run more programs simultaneously.
Which of the following statements about Moore’s Law is true?
A. Moore’s Law states that the computing power of devices will increase at a steady rate over time
B. Moore’s Law is no longer applicable as computing power has reached its maximum potential
