Question #1
What is the function of the 'Capacitor' component inside a standard Dynamic RAM (DRAM) cell structure?
A. To convert incoming alternating current lines into stable direct current.
B. To protect the chip traces against high-voltage static electricity shocks.
C. To regulate the internal operating frequency clock of the memory stick.
D. To store an electrical charge that represents a single binary bit value (0 or 1).

Correct Answer: Option D


Explanation:
A single DRAM memory cell consists of one transistor and one capacitor. The capacitor holds an electrical charge to represent a 1 or no charge to represent a 0.
