Which characteristic makes Static RAM (SRAM) different from Dynamic RAM (DRAM)?
A. SRAM is cheaper and denser than DRAM.
B. SRAM is volatile while DRAM is non-volatile.
C. SRAM is slower than DRAM.
D. SRAM uses flip-flops to store data and does not require continuous refreshing.
Answer: Option D
Solution (By JKSSB Mock Tests)
SRAM uses flip-flops to retain data as long as power is supplied, making it faster and eliminating the need for periodic refreshing cycles unlike DRAM.
Explanation:
The control unit within the CPU coordinates data routing and instruction fetching operations between internal storage areas, registers, and system memory.
Explanation:
The read/write head is the component that reads data from and writes data to the platters. The actuator arm moves the head, and the spindle rotates the platters.
Explanation:
CD-RW discs use a phase-change material that can transition between crystalline (reflective) and amorphous (absorbent) states via laser heating to clear or write data.
