Electronics are characterized by . . . . . . . . A. Low cost B. Low weight and volume C. Reliability D. All of the mentioned

The correct answer is D. All of the mentioned.

Electronics are characterized by low cost, low weight and volume, and reliability.

• Low cost: Electronics are typically much cheaper than their mechanical counterparts. For example, a digital watch is much cheaper than a mechanical watch.
• Low weight and volume: Electronics are typically much lighter and smaller than their mechanical counterparts. For example, a laptop computer is much lighter and smaller than a desktop computer.
• Reliability: Electronics are typically much more reliable than their mechanical counterparts. For example, a digital camera is much more reliable than a film camera.

These characteristics make electronics the preferred choice for many applications.
