Detailed explanation-1: -False. Most computers and electronic devices are digital, not analog. Digital devices use two discrete states: on and off. Analog devices, on the other hand, use a continuous range of values.
Detailed explanation-2: -SLR cameras are much heavier and larger than point-and-shoot cameras. Because the processor in a computer is particularly sensitive to current fluctuations, you always should use a surge protector. Because embedded computers are components in larger products, they usually are small and have limited hardware.
Detailed explanation-3: -Physical servers are easier to manage than virtual servers. Cloud computing uses server virtualization.
